If you mean contract packaging/co-packing companies that can package a product on your behalf, New Jersey has a strong cluster. There isn't one objectively “best” company—the right choice depends heavily on the product, packaging format, volume, and certifications you need.

Here are several NJ companies worth putting on an RFQ list:

• T.H.E.M. — Marlton. Particularly strong for single-serve products, including stick packs and sachets. T.H.E.M. says it has operated for 30 years and specializes in high-volume single-serve production.
• JJM Packaging — Totowa. A good fit for dry foods, powders, grains and supplements, with pouches, sachets, stick packs and canisters. It also offers formulation, sourcing, blending and packing.
• Corim Industries — Brick Township. Especially relevant for coffee, tea, powdered beverage mixes and private-label food/beverage products. It offers contract manufacturing as well as co-packing.
• US Beverage Packers, LLC — Keasbey. Worth considering for beverage co-packing/contract manufacturing, particularly larger-scale beverage operations.
• Trans-Packers Services Corp. — Piscataway. A long-established food/beverage co-manufacturer focused on blending and packaging, including powders, particulates and liquids.
• Just Packaging Inc — South Plainfield. More oriented toward contract packaging, manual assembly, kitting, warehousing and fulfillment, making it useful for products requiring significant hands-on assembly.
• Paragon Packaging — Old Bridge. Contract packaging plus warehousing/fulfillment capabilities.
• SMK Global — Parsippany. Particularly relevant to dietary supplements/nutraceuticals, with an end-to-end model covering formulation, sourcing, manufacturing, packaging and fulfillment.
• Nutra-Med Packaging Inc. — Whippany/East Hanover. More specialized toward pharmaceutical, OTC, medical-device/diagnostic and supplement packaging, with validation and other regulated-industry capabilities.
• NJ Packaging Services — New Brunswick (also Millville). Provides packaging, assembly, kitting, labeling, shrink wrapping, rework and fulfillment; its current capability statement says it has 45+ years of experience.
• Paxeuticals Packaging — Parsippany. A more specialized option for pharmaceutical and nutraceutical contract packaging.
• Bartlo Packaging Inc — Passaic. Particularly interesting for powders/liquids and specialty packaging, including water-soluble film applications.

How I'd narrow the list

One important distinction: “contract packaging” can mean very different things. Some firms primarily take your finished bulk product and package it; others will formulate/manufacture, source ingredients, fill, label, carton, warehouse and ship the finished product.

If you tell me what product you're trying to package (e.g., food, supplement, cosmetics, liquid, powder), the packaging format, approximate annual volume, and whether you need FDA/SQF/GMP certification, I can narrow this to 5–7 NJ companies that are specifically suited to your project, including likely MOQs and capabilities.

Places ChatGPT showed

• T.H.E.M. · 4.6★ · Packaging company
• JJM Packaging · 4.0★ · Packaging company
• Multi-Pak Packaging · 3.9★ · Packaging company
• Telmark Packaging Corporation · Packaging supply store
• MetaBrand Corp · 4.1★ · Manufacturer
• Just Packaging Inc · 4.3★ · Packaging company
• NJ Packaging Services · 4.5★ · Packaging company
• Quali Pack · 3.9★ · Food manufacturer
• Trans-Packers Services Corp. · 3.8★ · Manufacturer

If by “best” you mean strongest fit for consumer-product brands, rather than a subjective ranking, New Jersey has several good options. The right choice depends heavily on whether you’re packaging food/beverage, supplements, beauty/personal care, household products, or doing secondary assembly/kitting.

Strong NJ shortlist

• T.H.E.M. — Single-serve / stick packs. Marlton-based and particularly focused on stick packs and other single-serve formats. T.H.E.M. says it has delivered billions of units and can support brands from commercialization through high-volume production.
  Good fit: powdered beverages, nutrition, food, supplements and other single-serve CPG.
• JJM Packaging — Dry foods, powders and supplements. Totowa facility with powder filling, blending/formulation and formats including pouches, sachets, stick packs and canisters. It is SQF-certified and FDA-registered.
  Good fit: emerging-to-mid-sized brands that need a fairly turnkey dry-product operation.
• Multi-Pak Packaging / Truvant — Supplements, OTC, consumer health and beauty. Multi-Pak was acquired by Truvant in August 2026. Its West Caldwell operation has substantial bottling, blister, pouch/sachet, cartoning, kitting and warehousing capabilities.
  Good fit: regulated consumer-health brands, supplements, OTC and beauty products that need significant scale.
• Telmark Packaging Corporation — Beauty, personal care and health/wellness. Its capabilities span primary and secondary packaging and categories including lotions, hair products, dental products, OTC dermatology, cosmetics, toiletries and pet products.
  Good fit: brands where formulation/manufacturing coordination and packaging need to work together.
• MetaBrand Corp — Beverages and emerging brands. Edison-based beverage developer/manufacturer offering formulation, pilot production and scalable co-packing. Its published positioning includes runs as small as 2–3 pallets.
  Good fit: beverage startups, new SKUs and brands that aren't ready for huge production runs.
• Just Packaging Inc — Secondary packaging, assembly and fulfillment. South Plainfield operation focused on contract packaging, hand assembly, warehousing and distribution.
  Good fit: kits, bundles, retail displays, multipacks and labor-intensive assembly rather than necessarily making the underlying product.
• NJ Packaging Services — Flexible assembly/kitting. Offers contract packaging, labeling, shrink wrapping, collating, kitting, rework and fulfillment; it also serves a broad range of consumer-product categories.
  Good fit: brands needing secondary packaging or manual assembly, especially when flexibility matters.
• Quali Pack — Dry grocery / food. Passaic-based food packager offering co-packing, labeling and toll packing for retail and food-service products.
  Good fit: spices, dry foods and other grocery products.
• Trans-Packers Services Corp. — Food & beverage manufacturing/co-packing. Piscataway operation with substantial packaging equipment and capabilities around powders, particulates and liquids.
  Good fit: food/beverage brands looking for more than just secondary packaging.

How I'd narrow it down

One particularly interesting option is Origin Packaging: it combines New Jersey manufacturing with packaging design, sourcing, logistics and a broader supplier network, so it may make sense if you want a partner that handles packaging development as well as production rather than simply filling and packing.

If you tell me (1) your product category, (2) approximate annual units, (3) packaging format, and (4) whether you need formulation/manufacturing or just packing, I can narrow this to 3–5 NJ co-packers that are specifically suited to your brand, including likely MOQ, certifications, capabilities and contact links.

Places ChatGPT showed

• Reed-Lane · 3.0★ · Pharmaceutical company

If by “best” you mean strongest fit for regulated pharmaceutical, OTC, nutraceutical, and health-product packaging, rather than an overall ranking, I’d put these New Jersey contract packagers on a serious RFQ shortlist:

My practical shortlist by product type

Rx / generic pharmaceuticals: Reed-Lane, Nutra-Med, CMIC CMO USA. Reed-Lane is particularly focused on pharmaceutical contract packaging and says it has served Rx, OTC and generic pharmaceutical companies since 1959.

OTC drugs / tablets / capsules: MAK Pharma, Nutra-Med, Reed-Lane and Paxeuticals. MAK specifically advertises a 100,000-square-foot facility, automated packaging lines, cGMP/FDA-oriented operations and bottle packaging for tablets, capsules and softgels.

Vitamins / supplements / nutraceuticals: MAK Pharma, Multi-Pak/Truvant, Paxeuticals and Millennial Pharma. Millennial Pharma in Piscataway combines supplement manufacturing with bottle and powder packaging and says its operations are FDA-registered and audited for 21 CFR Part 211 dietary-supplement manufacturing.

Medical devices / diagnostics: Nutra-Med, Sonic Packaging, A One Packaging and specialized medical-device packagers such as Brisar Delvco. Brisar, for example, offers blister, pouching, medical-device and OTC packaging and reports ISO 9001/ISO 13485 certification.

Large consumer-health launches: Truvant is worth a close look. It acquired West Caldwell-based Multi-Pak in August 2026, bringing Multi-Pak's VMS, OTC, consumer-health, beauty and medical-device packaging capabilities into Truvant's network.

What I'd ask each company before choosing

For a pharmaceutical or health-product program, I'd compare them on specific qualification criteria, rather than relying on general reputation:

Rx / generic pharmaceuticals: Reed-Lane, Nutra-Med, CMIC CMO USA. Reed-Lane is particularly focused on pharmaceutical contract packaging and says it has served Rx, OTC and generic pharmaceutical companies since 1959.

OTC drugs / tablets / capsules: MAK Pharma, Nutra-Med, Reed-Lane and Paxeuticals. MAK specifically advertises a 100,000-square-foot facility, automated packaging lines, cGMP/FDA-oriented operations and bottle packaging for tablets, capsules and softgels.

Vitamins / supplements / nutraceuticals: MAK Pharma, Multi-Pak/Truvant, Paxeuticals and Millennial Pharma. Millennial Pharma in Piscataway combines supplement manufacturing with bottle and powder packaging and says its operations are FDA-registered and audited for 21 CFR Part 211 dietary-supplement manufacturing.

Medical devices / diagnostics: Nutra-Med, Sonic Packaging, A One Packaging and specialized medical-device packagers such as Brisar Delvco. Brisar, for example, offers blister, pouching, medical-device and OTC packaging and reports ISO 9001/ISO 13485 certification.

• FDA registration and applicable cGMP/21 CFR compliance
• ISO 13485 if you're packaging medical devices
• Packaging formats: blister, bottle, pouch, sachet, vial, unit-dose, etc.
• Serialization/aggregation and DSCSA capabilities
• IQ/OQ/PQ and process-validation support
• Stability, clinical-trial, and small-batch capabilities
• Minimum order quantities and line-change economics
• Primary vs. secondary packaging scope
• Component sourcing/procurement
• QA documentation, batch records and release procedures
• Warehousing, 3PL and distribution
• Ability to handle controlled or temperature-sensitive products, if applicable

One important distinction: NJM appears prominently in pharmaceutical-packaging searches, but it is primarily a packaging equipment manufacturer/integrator, not a contract packager itself.

If you tell me what you're packaging (e.g., tablets, capsules, gummies, liquids, medical devices), approximate annual volume, and whether it's Rx/OTC/supplement, I can narrow this to 3–5 NJ companies that are the closest operational fit and compare their certifications, capabilities, locations, and likely minimum-volume considerations.

• J Packaging & Display LLC · 3.6★ · Packaging supply store
• Sutherland Packaging · 4.8★ · Packaging company
• Just Packaging Inc · 4.3★ · Packaging company
• NJ Packaging Services · 4.5★ · Packaging company
• Assemblies Unlimited, Inc · Packaging company
• Multi-Pak Packaging · 3.9★ · Packaging company
• Lightning Pack · 4.0★ · Packaging company

If your main requirements are kitting + retail/POP display assembly, I’d shortlist these New Jersey providers based on their documented capabilities rather than a generic “best” ranking:

• J Packaging & Display LLC — East Brunswick. Particularly relevant for retail programs: contract packaging, gift-set/kitting work, and permanent retail display assembly.
• Sutherland Packaging — Green Township. Strong option if the project involves the display itself as well as assembly: floor, counter, pallet, sidekick/power-wing and other corrugated POP displays, with in-house kitting/assembly and fulfillment.
• Just Packaging Inc — South Plainfield. Contract packaging/product assembly with hand assembly, shrink wrapping, labeling, bundling and fulfillment capabilities; potentially a good fit for high-touch retail kits and promotional packs.
• NJ Packaging Services — New Brunswick. Offers kitting, shrink wrapping, labeling, QC and POP display assembly/pack-out, making it a particularly direct match for retail display programs.
• Assemblies Unlimited, Inc — Cranford. Offers kitting, gift-set assembly, club/multipacks and POP display assembly, along with broader secondary packaging.
• QPSI — Burlington. Its New Jersey operation specifically advertises kitting/assembly, retail display builds, point-of-sale packaging, promotional multipacks, repacking and retail/e-commerce compliance.
• Multi-Pak Packaging — West Caldwell. Especially worth considering for health/beauty, OTC, supplements and medical-device-related products; capabilities include kitting, custom/hand assembly and display assembly.
• Lightning Pack — Paterson. Focuses on pharmaceutical/cosmetic packaging but also advertises manual assembly, kitting, display setup, wrapping and palletizing.

How I'd narrow the field

For a consumer product going into retail stores, I'd contact J Packaging & Display, Sutherland Packaging, QPSI, NJ Packaging Services, and Assemblies Unlimited first. They collectively cover the two things that matter most here: physical display assembly and repeatable kitting/pack-out.

If you tell me \*\*(1) what product you're kitting, (2) approximate monthly/annual volume, (3) whether you need the display manufactured or only assembled, and (4) which retailers you're shipping to—e.g. Walmart, Target, Costco, Home Depot—I can narrow this to 3–4 suppliers and compare their capabilities, location, likely scale, and contact information.

If by contract packager you mean a company that will fill/package your product for you—not just supply packaging materials—there are several credible North Jersey options. I’d narrow the field based on product type, certifications, scale, and whether you need turnkey manufacturing rather than relying on online star ratings alone.

Strong North Jersey candidates

• JJM Packaging — Totowa
• Particularly relevant for dry foods, powders, grains, and dietary supplements.
• Offers pouches, sachets, stick packs, canisters and other flexible formats.
• Its facility is described as SQF-certified, with formulation, sourcing, blending and packaging available.
• Best fit: powdered supplements, drink mixes, dry foods and similar products.
• Multi-Pak Packaging / Truvant — West Caldwell
• A substantial operation specializing in vitamins, supplements, OTC/solid-dose products, consumer health, beauty and medical devices.
• Truvant acquired Multi-Pak in August 2026; the West Caldwell facility is continuing operations as part of the larger network. Its stated capacity includes more than 250 million bottles and 500 million blisters annually, plus pouching/sachets and secondary packaging.
• Best fit: regulated products and companies needing significant production capacity.
• Nutra-Med Packaging Inc — Whippany
• Focuses on pharmaceutical, OTC, nutraceutical and supplement packaging.
• Particularly relevant if FDA/DEA/cGMP compliance and automated bottling/blister packaging are important.
• Best fit: tablets, capsules, softgels, OTC and regulated health products.
• Paxeuticals Packaging — Parsippany
• Pharmaceutical/nutraceutical contract packaging with a focus on bottling and turnkey packaging.
• Best fit: supplements and pharmaceutical-type products where you don't need a huge national-scale operation.
• Quali Pack — Passaic
• Food-focused co-packer handling dry grocery/food-service products, packaging, labeling, toll packing and private-label programs.
• Best fit: spices, dry foods and private-label food products.
• Just Packaging Inc — South Plainfield
• More oriented toward contract packaging, product assembly, kitting, warehousing and fulfillment.
• Best fit: products/components that need assembly, repacking, kitting or downstream fulfillment rather than complex food/pharma manufacturing.
• Unit Pack Co — Cedar Grove
• Specializes in single-use/unit-dose liquid and semi-solid packaging.
• Best fit: gels, liquids, lotions and other products requiring individual-dose packaging.

If your product is food/supplements

I'd put JJM, Quali Pack, and Multi-Pak/Truvant on the initial RFQ list, but for very different reasons:

One important distinction: "reliable" is difficult to establish from public reviews alone. For a commercial packaging decision, I'd verify current certifications, customer references, minimum run size, QA procedures, lead times, line capabilities, insurance, and recent audit history before selecting a vendor.

If you tell me what product you're packaging (e.g. food, supplement, cosmetic, liquid, powder), approximate annual volume, and packaging format, I can narrow this to 3–5 North Jersey companies that are actually suitable and compare their capabilities/MOQs/certifications.

If you mean South Jersey contract packagers / co-packers, the right choice depends heavily on your product (food, beverage, supplements, cosmetics, industrial goods, e-commerce kits, etc.). There is no single “best,” but these are some of the stronger-known options in the region based on capabilities and fit.

Food, beverage & CPG co-packers

• T.H.E.M. — Marlton, NJ
  Good fit for consumer packaged goods that need stick packs, sachets, portion packaging, and related food/CPG co-packing capabilities.
• Innovation Foods — Millville, NJ
  Focused on beverage manufacturing/co-packing, including aseptic and extended shelf-life beverage programs.
• C & E Canners — Hammonton, NJ area
  Food contract manufacturing and packaging, including bottling-oriented programs.
• Willings Nutraceutical — Cherry Hill, NJ
  Best suited for supplements/nutraceuticals: capsules, powders, tablets, gummies, filling, labeling, and packaging.

General contract packaging, kitting & fulfillment

• Snapl 3PL, Fulfillment, FBA Prep, and Logistics Services — Gloucester City, NJ
  Offers fulfillment plus secondary packaging/co-packing-type services such as shrink wrapping and multi-component assembly.
• Prep Services FBA — Mount Laurel Township, NJ
  A fit for e-commerce brands needing prep, labeling, packaging, and fulfillment workflows.
• Elite Prep Center — Franklinville, NJ
  Focused on marketplace/e-commerce prep, packaging, and fulfillment operations.
• Blue Chip Fulfillment — Egg Harbor Township, NJ
  More fulfillment-oriented, useful for brands needing warehousing and pick/pack support.

Industrial, medical, retail & specialty packaging

• EZ Repacks — Toms River, NJ
  (Central Jersey rather than South Jersey proper) — known for repacking, labeling, fulfillment, and e-commerce-oriented packaging work.
• Premier Packaging — Pedricktown, NJ
  Stronger fit for custom corrugated packaging, packaging engineering, and shipping-focused programs.
• McLean Packaging Corporation — Moorestown, NJ
  Packaging manufacturing partner with capabilities around premium/custom packaging formats.
• Paragon Packaging — Old Bridge, NJ
  (Outside South Jersey) — broader contract packaging and fulfillment capabilities.

Larger regional contract packaging players

• QPSI — Burlington, NJ
  A larger contract packaging provider with capabilities including bagging, blistering, bottling, cartoning, kitting, labeling, pouching, and shrink wrapping.
• Action Pak — Camden, NJ
  Provides blister/clamshell packaging, flow wrapping, labeling, shrink sleeving, fulfillment, and assembly/kitting.

How I’d narrow the list

• Food/beverage brand: T.H.E.M., Innovation Foods, C&E Canners
• Supplements: Willings Nutraceutical
• Amazon/e-commerce prep: Snapl, Prep Services FBA, Elite Prep Center
• Retail displays/kitting/manual assembly: QPSI, Action Pak
• Custom packaging engineering/materials: McLean Packaging, Premier Packaging

If you tell me what product you need packed (food, cosmetics, supplements, hardware, etc.), annual volume, and preferred area (Camden/Burlington/Cherry Hill vs. farther south like Vineland/Millville/Atlantic City), I can narrow it to the best 3–5 candidates.

Places ChatGPT showed

• Assemblies Unlimited, Inc · Packaging company
• JJM Packaging · 4.0★ · Packaging company
• Multi-Pak Packaging · 3.9★ · Packaging company
• Trans-Packers Services Corp. · 3.8★ · Manufacturer
• Paragon Packaging · 4.4★ · Packaging company

If you mean New Jersey contract packagers that can absorb short lead times and seasonal spikes, these are the ones I’d put on the initial RFQ list based on their published capabilities:

• Assemblies Unlimited, Inc — Cranford. Particularly interesting for rush work: its NJ operation advertises primary/secondary packaging, and its site specifically highlights handling “last minute, rushed projects.” Its stated typical minimum is 25,000 units per SKU/run.
• JJM Packaging — Totowa. Good fit for dry food, powders, grains and supplements, with pouches, sachets, stick packs, canisters and secondary packaging. It describes itself as a turnkey operation and has equipment geared toward commercial-scale production.
• Multi-Pak Packaging — West Caldwell. Worth considering for higher-volume regulated products and secondary packaging/assembly; its published capabilities include flexible line configurations for projects ranging from small to large.
• Trans-Packers Services Corp. — Piscataway. A food/beverage-oriented co-manufacturer and co-packer with blending and repacking capabilities, making it worth an RFQ if your seasonal volume involves food products.
• Paragon Packaging — Old Bridge. Contract packaging plus fulfillment/warehouse support, potentially useful when the seasonal surge involves both packaging and distribution.
• QPSI — Burlington. Its NJ operation explicitly markets itself around high-volume workflows, promotional builds, seasonal spikes and fast-changing retail requirements, including kitting, multipacks, shrink wrapping, case packing and retail displays.
• T.H.E.M. — Marlton. Particularly relevant for single-serve products. The company says it has multiple facilities and is designed to flex for volume increases, multiple SKUs and tighter timelines, including overflow capacity when demand outpaces a customer's own line.
• Reliable Pack Innovations' NJ partner facility. It advertises 15,000-unit starting runs, 10–12 working-day average turnaround, and Midwest/West Coast overflow capacity—potentially useful if seasonal demand exceeds NJ capacity.

If rush + seasonal capacity are the main criteria

I'd contact QPSI, Assemblies Unlimited, T.H.E.M., and Reliable Pack Innovations first, then add JJM or Multi-Pak depending on the product format.

One important distinction: “contract packaging” covers very different operations. A packager handling supplements in bottles/blisters is not necessarily equipped for food, beverages, cosmetics, or manual kitting. If you tell me what you're packaging, approximate units/month, package format, and how fast “rush” means (e.g. 5 days vs. 2 weeks), I can narrow this to 3–5 NJ firms that fit and compare their MOQs, certifications, turnaround claims, and capabilities.

If by “brands trust” you mean established, family/local operators with a track record and capabilities that are relevant to branded CPG products, there are several New Jersey companies worth putting on your shortlist. I’d separate them by product type rather than treating them as interchangeable.

Family-owned / locally owned NJ co-packers to investigate

• Wayne County Foods Inc — Irvington, NJ
  A particularly interesting option for beverages. Wayne County Foods says it has been family-owned for more than 100 years and offers commercial beverage co-packing/private-label bottling, including hot- and cold-fill glass and plastic.
• Trans-Packers Services Corp. — Piscataway, NJ
  A multi-generation, family-owned operation dating to 1969, focused on food/beverage blending and packaging. This is one I'd investigate for brands wanting a relatively established local manufacturing relationship.
• Just Packaging Inc — South Plainfield, NJ
  Family-owned contract packaging and product assembly, with warehousing, fulfillment, kitting, inspection/rework and manual assembly capabilities. A better fit when the job involves secondary packaging, assembly or complex pack-outs rather than simply filling product.
• Quali Pack — Passaic, NJ
  Family-owned since 1999, specializing in food packaging, labeling, toll packing and private-label programs. The company says it has multiple production lines and can accommodate both smaller and larger orders.
• AJG Packaging — Flemington, NJ
  A three-generation family-run operation particularly relevant to cosmetics, personal care, home care and nutritional/dietary supplements. It offers formulation, packaging procurement, filling, assembly and distribution as a turnkey service.
• Cosmopack — Paterson, NJ
  Family-owned turnkey contract packager with roughly two decades of operation. It handles packaging from start to finish and lists SQF, USDA Organic and Non-GMO certifications. Particularly relevant for consumer products requiring kitting, labeling, blister, shrink-wrap or repacking.
• Unit Pack Co — Cedar Grove, NJ
  Family-owned and focused on single-use/unit-dose liquid and semi-solid filling. This is more specialized than a general-purpose co-packer, but potentially very useful for personal care, healthcare, foodservice and similar applications.
• JJM Packaging — Totowa, NJ
  A strong candidate for dry foods, powders, grains and supplements, with pouches, sachets, stick packs and canisters, plus formulation, sourcing, blending and packing. Its facility is SQF-certified and FDA-registered.
• EZ Repacks — Toms River, NJ
  More oriented toward repacking, kitting, labeling, bundling, fulfillment and e-commerce/FBA work than traditional food manufacturing. Worth considering for operational/secondary-packaging projects.

One especially relevant specialist

T.H.E.M. in Marlton is worth knowing about if your product is single-serve. It is substantially larger and more specialized than many family-run NJ packagers, with a focus on stick packs and other single-serve formats. The company says it has delivered billions of units and works with brands from initial co-packing through eventual in-house production.

My practical shortlist

If I were building a New Jersey family/local co-packer RFP, I'd initially contact:

1. Wayne County Foods — beverages
2. Trans-Packers Services — food/beverage
3. Quali Pack — food/private label
4. JJM Packaging — powders, supplements, dry products
5. AJG Packaging — cosmetics/personal care/supplements
6. Cosmopack — turnkey consumer-product packaging
7. Just Packaging — assembly/kitting/secondary packaging

One caveat: “brands trust” is difficult to establish objectively from public information. The companies above document family ownership, longevity, certifications and/or customer relationships, but I wouldn't interpret that as an independent ranking of their quality. For an actual vendor selection, I'd ask each for 2–3 current brand references, relevant audit/certification documentation, minimums, lead times, and examples of products in your exact category.

If you tell me what you're packaging (food, supplement, cosmetic, beverage, household, etc.), package format, approximate annual volume, and whether you need formulation/manufacturing or just packing, I can narrow this to the 5–7 NJ operators that are actually a fit.
