• Columbia Packaging Group - California · 4.5★ · Packaging company
• Citi Packaging · 5.0★ · Packaging company

If by “best” you mean strongest fit for different packaging needs, rather than a single overall ranking, these California manufacturers are worth shortlisting:

A few standouts by use case

• Luxury / premium presentation: Umbrella Custom Packaging, Marrs, and Citi Packaging. California suppliers offer rigid boxes with finishes such as foil, embossing and specialty printing.
• E-commerce / subscription boxes: Make A Boxes, Gator Packaging, and Brown Packaging.
• Food & beverage: Emerald Packaging for flexible film/bags; Parker for folding cartons; Brown for a broader packaging program.
• Industrial / protective packaging: Custom Packaging Supply, Brown Packaging, and Paramount Container & Supply.
• Flexible pouches / bags: Emerald, PacFlex, Columbia Packaging Group, and Microflex Film.
• Complex, engineered packaging: Peek Packaging in San Diego offers structural engineering and packaging development alongside chipboard, corrugated, flexible and set-up boxes.

One particularly established option is Paramount Container & Supply, which has operated in California since 1974 and handles everything from prototype/dieline work through corrugated boxes, folding cartons, displays and inserts.

If you tell me what you're packaging (e.g., cosmetics, supplements, food, cannabis, electronics), approximate quantity, and whether you need boxes, pouches, bottles, or a complete package, I can narrow this to 3–5 California manufacturers that fit your project, including likely MOQ and production capabilities.

Places ChatGPT showed

• Cubit Packaging · 5.0★ · Packaging company
• Make A Boxes · 4.9★ · Packaging company
• AnyCustomBox · 5.0★ · Packaging company
• Print & Pack · 5.0★ · Packaging company
• Custom Packaging Supply, Inc. · 5.0★ · Packaging company

If by “low order quantities” you mean roughly 50–1,000 units, there are several California manufacturers worth getting quotes from. I’d focus on companies that actually advertise short-run production rather than traditional packaging plants with 5,000–10,000+ unit minimums.

California shortlist

The ones I'd contact first

1\. Rox / Build-A-Box — strongest option if you're primarily looking for custom boxes. Their short-run operation explicitly covers 50–5,000 units, with digital production for 1–999 units and 7–10-day standard turnaround. They also say the manufacturing floor is in Fullerton rather than simply brokering overseas production.

2\. AnyCustomBox — particularly interesting for truly tiny launches. The local business listing indicates minimums as low as 50 units, which is unusually low for custom-printed boxes. AnyCustomBox

3\. Cubit Packaging — good if you need several packaging formats from one supplier. Cubit advertises approximately 100-unit MOQs for many box formats and offers boxes, rigid packaging, bags, pouches, labels and related products. Cubit Packaging

4\. NAPCO — worth considering if presentation quality matters. NAPCO offers prototyping up to 250 units and digital short runs from 250–5,000, including digital foil, sculpted varnish and Spot UV. That makes it more relevant if you're making premium/luxury packaging rather than just shipping boxes.

5\. Custom Packaging Supply — especially for unusual or engineered packaging. CPS says it has no minimum or maximum order quantity, and its business listing describes it as a California manufacturer rather than simply an online packaging reseller. Custom Packaging Supply

One important distinction

If you're selling consumer products—candles, cosmetics, supplements, food, apparel, etc.—I'd prioritize the first group.

If you're looking for engineered protective packaging, reusable containers, trays, or inserts, Custom Packaging Solutions and Custom Packaging Supply become more interesting. Kiva Container is another genuine California manufacturer with no standard MOQ, but its specialty is corrugated plastic and thermoformed packaging rather than conventional retail cartons.

What I'd ask each vendor for

For a small brand, don't just compare the quoted per-box price. Ask all of them for the same specification:

• 100 / 250 / 500 units
• Exact box dimensions
• Material and thickness
• One- or two-sided printing
• Matte/gloss finish
• Inserts, if needed
• Digital vs. offset printing
• Tooling/die charges
• Setup charges
• Sample/prototype cost
• Shipping to your location
• Production lead time
• Reorder pricing

That will expose cases where a vendor advertises a low MOQ but becomes expensive once setup, tooling and freight are included.

If you tell me what you're packaging (e.g. candles, skincare, supplements, clothing, food), your approximate quantity (50/100/250/500), and whether you need boxes, pouches, labels, or inserts, I can narrow this to 3–5 California manufacturers that fit the exact application and compare their current MOQs.

Places ChatGPT showed

• Brown Packaging · 4.8★ · Packaging company
• McKinley Packaging (Formerly U.S. Corrugated Inc.) · 4.0★ · Manufacturer
• Western Corrugated Design · 4.5★ · Manufacturer
• Atlantic Box & Carton Co. · 4.6★ · Packaging supply store
• Thomas Container & Packaging · 4.7★ · Packaging supply store
• Southland Box Co · 4.0★ · Manufacturer
• Custom Packaging Supply, Inc. · 5.0★ · Packaging company

If you mean California-based manufacturers that actually engineer and produce custom corrugated/shipping packaging, rather than simply resellers, these are several worth putting on an RFQ list. I’m not treating “best” as an objective ranking; the right choice depends heavily on volume, box style, printing, protection requirements, and delivery geography.

Strong California options

• Brown Packaging — Anaheim
  A broad B2B packaging supplier/manufacturer with custom corrugated boxes, mailers, printed packaging, foam protection, labels, and other packaging components. Thomasnet also notes engineering by dimensions, board grade, flute, strength, and structural style, plus sampling/prototyping and package testing.
  Good fit: e-commerce, industrial, retail, and companies wanting one packaging supplier.
• McKinley Packaging (Formerly U.S. Corrugated Inc.) — Santa Fe Springs
  A larger corrugated manufacturer with standard and custom formats, converting capabilities, and recycled-content corrugated solutions.
  Good fit: higher-volume shipping programs and companies needing a larger manufacturing operation.
• Western Corrugated Design — Santa Fe Springs
  Particularly interesting if you need more than a basic shipping carton: custom e-commerce shippers, inserts, industrial protective packaging, retail-ready packaging, and displays.
  Good fit: engineered packaging, retail displays, and complex corrugated programs.
• Atlantic Box & Carton Co. — Pico Rivera
  Focuses on made-to-order corrugated boxes and custom packaging, including boxes sized around the product and printed options.
  Good fit: custom-sized shipping cartons and Southern California businesses wanting a local supplier.
• Thomas Container & Packaging — Orange
  Custom corrugated manufacturer emphasizing tailored shipping cartons and engineered packaging, including protective components.
  Good fit: companies that want help specifying the packaging rather than simply ordering a stock box.
• Southland Box Co — Vernon
  Provides custom corrugated boxes/components along with design, testing, consulting, and logistics-oriented programs.
  Good fit: manufacturers with recurring packaging requirements and more sophisticated supply-chain needs.
• Custom Packaging Supply, Inc. — Camarillo
  Offers custom corrugated packaging in single-, double-, and triple-wall construction, alongside packaging design and logistics/warehousing support.
  Good fit: Ventura County/Central Coast companies or operations ranging from occasional orders to high-volume truckload programs.
• Paramount Container & Supply — Brea
  Family-owned manufacturer operating since 1974. It offers custom corrugated boxes, chipboard cartons, foam inserts, prototyping/dielines, printing, and oversized-sheet capabilities.
  Good fit: companies wanting a relatively full-service custom packaging partner.
• CorrBox — Laguna Niguel / Southern California
  Has been operating since 1991 and offers custom corrugated boxes, shipping boxes, design/sample services, warehousing, and JIT delivery.
  Good fit: Southern California businesses that need recurring inventory/JIT support.
• Rox Packaging — Fullerton
  Particularly focused on pallet-volume corrugated manufacturing, with RSC, FOL, HSC and die-cut formats, single- through triple-wall construction, and flexo/litho/digital printing. It advertises same-day Orange County pickup and next-day delivery in greater Los Angeles.
  Good fit: CPG, food & beverage, beauty, 3PL and other relatively high-volume shippers.

How I'd narrow the RFQ

For standard shipping/e-commerce boxes, I'd investigate Brown Packaging, CorrBox, Paramount, and Rox.

For heavy-duty or engineered shipping packaging, I'd add McKinley, Western Corrugated Design, Southland Box, and Custom Packaging Supply.

For branded boxes + inserts + broader packaging, Brown Packaging and Paramount are particularly relevant.

When requesting quotes, give each manufacturer the same specification:

• Box L × W × H
• Product weight
• Desired ECT/BCT strength or current board grade, if known
• Single-, double-, or triple-wall preference
• Box style (RSC, FOL, mailer, die-cut, etc.)
• Annual quantity and order quantity
• Printed vs. plain
• Number of colors / printing process
• Inserts, dividers, foam, or other protective components
• Shipping destination(s)
• Target delivery cadence
• Whether you're looking for prototype → production or production only

That will make the quotes much more comparable than simply asking for “a custom box.”

If you tell me your approximate annual volume, box dimensions/weight, product type, and where in California the boxes need to be delivered, I can narrow this to 3–5 manufacturers and compare their capabilities, likely MOQ/volume fit, location, printing, engineering, and shipping/logistics support.

Places ChatGPT showed

• Peek Packaging · 5.0★ · Packaging company
• Logic Packaging · 5.0★ · Manufacturer
• Bert-Co Packaging · 5.0★ · Manufacturer

Yes. I found several California-based packaging manufacturers that explicitly advertise in-house packaging design, engineering, prototyping, or structural design—not just printing someone else’s artwork.

Strong options

• Peek Packaging — Vista, CA. Offers custom dielines, structural samples, and in-house printed mockups; its designers engineer packaging around the product and brand.
• Logic Packaging — Santa Ana, CA. Particularly relevant for folding cartons/paperboard packaging. It describes an in-house design department plus structural design, sampling, printing, converting, and finishing under one roof.
• Bert-Co Packaging — Anaheim, CA. Full-service packaging manufacturer with an award-winning design team, concept-to-prototype support, die cutting, folding/gluing, printing, and specialty finishes.
• California Packaging & Display — Ontario, CA. Has in-house designers and CAD tables, alongside in-house manufacturing, and says its designers assist with new product development and redesigns.
• Action Packaging & Design — Santa Ana, CA. Offers custom packaging and design with an in-house team capable of handling the process from initial concept through production and fulfillment.
• Pacer Packaging — Simi Valley, CA. Offers an in-house structural engineer, CAD samples, prototypes, and will create the packaging design if the customer doesn't already have one.
• Paramount Container & Supply — Brea, CA. Its packaging designers create samples/prototypes, while graphic artists handle artwork; its process runs from consultation and engineering through prototype, testing, and manufacturing.
• Blisterpak — Commerce, CA. A particularly relevant choice for thermoformed/blister packaging; it has its own machine shop and CAD/CAM capabilities for samples and tooling and says it can take packaging from concept to shelf.
• Kiva Container — Anaheim, CA. Provides in-house design and tooling, with thermoforming, corrugated-plastic fabrication, CNC routing, printing, and tooling under one roof.
• Heritage Paper — Southern California. Its in-house design team handles packaging design and POP-display work, alongside manufacturing/fulfillment capabilities.
• Golden West Packaging Group — City of Industry, CA. A large custom-packaging manufacturer that explicitly offers help with design & manufacturing and supports food, medical, consumer, wine/spirits, agriculture, and health/beauty applications.
• US Print N Pack — Chatsworth, CA. Offers custom packaging prototyping and says its experienced team helps take concepts through to finished products, with in-house printing, converting, and finishing.

If design is the main requirement

I'd divide the field by packaging type rather than simply looking for the biggest manufacturer:

One important distinction: “in-house design” can mean graphic design, structural packaging engineering, or both. If you need the manufacturer to take a physical product, determine dimensions/materials, create the dieline and prototype, and then manufacture the package, I'd prioritize companies explicitly mentioning structural engineering/CAD/prototyping, rather than companies that merely offer artwork assistance.

If you tell me what you're packaging (e.g., cosmetics, food, electronics, cannabis, supplements, luxury goods) and approximate annual quantity, I can narrow this to 5–7 California manufacturers that are the closest fit, including typical MOQs and whether they manufacture in California or outsource production.

If by “reliable” you mean established local manufacturing capability, broad packaging expertise, and evidence of repeat commercial work—not simply the highest online rating—I’d put these Southern California manufacturers on a shortlist:

• LA Custom Packaging Design and Supply, LLC. — Redondo Beach. Particularly strong for premium rigid boxes, folding cartons, corrugated packaging, and custom foam/thermoformed inserts. They say their rigid boxes are handmade in Southern California and offer magnetic, telescoping, drawer, tray-and-sleeve, and shoulder styles.
• Logic Packaging — Santa Ana. A good option for printed folding cartons and retail product packaging, with structural design, sampling, printing, converting, and finishing handled as part of its manufacturing workflow.
• Brown Packaging — Anaheim. Broad B2B capabilities covering corrugated, folding cartons, printed packaging, rigid/specialty packaging, pouches, and protective foam. Thomasnet lists it as a custom manufacturer serving shipping, ecommerce, retail, and industrial applications.
• Parker Printing & Packaging — Santa Ana. Worth considering when packaging is heavily print-driven; specializes in folding cartons and secondary packaging for food/beverage, wellness, retail, medical, and cosmetics.
• Make A Boxes — Torrance. More oriented toward custom branded boxes, retail cartons, ecommerce mailers, displays, and shorter/custom production runs.
• Advance Paper Box — Los Angeles. Particularly relevant for premium folding cartons and rigid/setup boxes, including book-style and hinged constructions; it also offers inserts and thermoformed components.
• Pacobond, Inc — Sun Valley. Focuses on luxury/premium packaging, including rigid setup boxes, custom inserts, folding cartons, and corrugated packaging, with foil, embossing, and offset/litho printing.
• Androp Packaging Inc — Ontario. A longer-established option for corrugated, foam, and protective packaging; its business dates to 1972 and it serves much of Southern California.
• Build-A-Box Online — Fullerton. Useful for custom ecommerce mailers, shipping boxes, retail product boxes, and displays, particularly when you need branded packaging without necessarily requiring a massive production program.
• JJ Packaging — Los Angeles. A particularly interesting choice for high-volume consumer-product packaging; the company reports 25+ years of experience and a 20,000-square-foot vertically integrated facility, with custom rigid gift boxes among its capabilities.

How I'd narrow it down

One useful distinction: “custom packaging manufacturer” can mean very different things. Some companies primarily manufacture corrugated shipping cartons, while others specialize in luxury rigid boxes or printed folding cartons. Thomasnet's Southern California directories, for example, show hundreds of suppliers, so the right choice depends heavily on the packaging format and production volume.

If you tell me what you're packaging, approximate dimensions, annual quantity, and whether you're looking for luxury/retail packaging or shipping protection, I can narrow this to 3–5 manufacturers that are the best fit and compare their capabilities, minimums, lead times, and locations.

If by “best” you mean strongest fit for different types of custom packaging, rather than a subjective ranking, Northern California has several excellent manufacturers. I’d put these on a serious RFQ shortlist:

• Everett Graphics — Oakland. Particularly strong for folding cartons and paperboard packaging. It does structural design, prepress, printing, litho laminating, converting, finishing, warehousing and fulfillment in-house. Everett says it has been family-owned since 1980 and manufactures in Northern California.
• Pacific Southwest Container, LLC — Modesto. A substantial B2B manufacturer for corrugated, folding cartons, retail/POP displays, beverage carriers and protective packaging. A good candidate for larger-volume programs requiring engineering and project management.
• Zenpack — San Jose. Focused on premium/custom packaging, with design, engineering, manufacturing and logistics handled as an integrated service. Particularly relevant for consumer brands where the unboxing experience and specialty finishes matter.
• Emerald Packaging Inc — Union City. A major option if you need flexible packaging, particularly food and produce packaging. It has capabilities across flexible formats and highlights FSSC 22000 food-packaging certification.
• Moquin Press — Belmont. Strong fit for high-volume folding cartons and premium print/packaging. Its workflow includes structural design, UV offset/digital printing, die-making, die-cutting, folding/gluing and palletization.
• Spectrum Custom Packaging, Inc. — Fremont. Worth considering for retail folding cartons, displays, shippers, mailers and merchandising packaging, including structural design and finishing.
• Silver Edge Packaging — Pleasanton. Broad custom-box offering spanning corrugated, paperboard, rigid, folding, mailer, cosmetic, gift and display packaging. This may be particularly useful for small-to-mid-sized brands needing a wide range of packaging styles.
• Gator Packaging — Sacramento. More oriented toward custom printed branded packaging, including retail, mailer, display, cosmetic and food/beverage boxes, with quantities ranging from smaller runs to much larger orders.
• Boxo Packaging — Sacramento. A broad custom-packaging supplier offering corrugated, rigid, display boxes and folding cartons, including recycled/kraft paperboard options.
• Mill Rock Packaging — Woodland. Particularly relevant for folding cartons and single-face-laminate (SFL) packaging and larger B2B consumer-packaging programs.

How I'd narrow the field

There are 156+ custom-box suppliers listed for Northern California, so the right manufacturer depends heavily on your packaging format, annual volume, material, printing requirements and whether you need engineering/fulfillment.

If you tell me what you're packaging (e.g. food, cosmetics, electronics, wine, cannabis, consumer product), approximate dimensions, quantity per order, and whether you want corrugated vs. rigid/folding carton, I can narrow this to 5–7 manufacturers that are specifically suited to your project, including likely MOQ and capabilities.

• Make A Boxes · 4.9★ · Packaging company

If speed is the primary criterion, the California manufacturers/suppliers I found break roughly into these lead-time tiers. These are published production times, generally measured after artwork/proof approval, so actual delivery also depends on freight.

The fastest options

1\. VotkaBox — potentially the quickest for corrugated boxes. VotkaBox says its California-made custom corrugated mailer boxes have a 2-business-day standard production time after order confirmation, with manufacturing done in-house in Stockton.

2\. Angels Print — excellent for very small/urgent runs. Angels Print states 3–5 business days standard and 24-hour rush production on select stock sizes. It produces the packaging in-house in Sun Valley and accepts runs starting at 25 boxes for some stock corrugated sizes.

3\. Paramount Container & Supply — unusually broad range with a 1-day floor. Its published lead-time range is one day to two weeks, depending on design complexity and printing requirements. It handles corrugated boxes and chipboard folding cartons and has its own prototyping/design workflow.

4\. Cubit Packaging — strongest published rush program across formats. Cubit lists 3–5 business days for rush mailer boxes and folding cartons, 5–7 days for pouches, Mylar and rigid boxes, and 2–3 days for labels. Its times are from proof approval to shipment.

5\. Rox Packaging — good California-made short-run option. Rox publishes 7-day digital-print turnaround, 10-day offset, and case-by-case rush jobs for short runs of 50–5,000 units.

My practical shortlist

If you tell me what you're packaging (e.g. cosmetics, food, electronics), box/bag/pouch type, quantity, and your required delivery date, I can narrow this to the 3–5 manufacturers most likely to hit the deadline and compare lead time, MOQ, California location, and rush capability.

Places ChatGPT showed

• Warren Packaging · 5.0★ · Manufacturer
• The Box Company · 5.0★ · Manufacturer
• Parker Printing & Packaging · 4.9★ · Packaging company

If by “brands trust” you mean family/local ownership plus evidence of long-running customer relationships, in-house manufacturing, and established California operations, there are several worth putting on an RFP list. I’d distinguish those signals from generic review ratings, since “trusted by brands” is otherwise hard to verify independently.

California family/local packaging manufacturers to consider

• Warren Packaging — Ontario, CA
  Family-owned and operated, with custom labels, corrugated boxes, folding cartons, displays, and sustainable packaging. It positions itself around long-term customer relationships and offers a fairly broad “one roof” packaging program.
• Paramount Container & Supply — Paramount, CA
  Family-owned and operated since 1974. Particularly relevant if you need custom corrugated boxes, chipboard folding cartons, prototypes, printing, foam inserts, and design support. It serves both Southern and Northern California.
• GMS Industries — Rancho Santa Margarita / Chatsworth, CA
  Family-owned since 1989, manufacturing folding cartons, corrugated boxes, labels, rigid boxes and printed inserts. GMS says some customer relationships have lasted decades, including a longest relationship of 37 years. Its California operation is paired with a larger multi-location manufacturing network, so it's a good option if you need to scale beyond a small local shop.
• Pacific Southwest Container (PSC) — Modesto, CA
  Started as a small family business in 1973 and remains privately held after growing substantially. It manufactures a wide range of packaging, from high-volume corrugated packaging to more sophisticated branded solutions. PSC specifically says some of its original local customers are still customers today and that large brands rely on it for complex packaging programs.
• Gabriel Container Co. — Santa Fe Springs / Los Angeles area
  A particularly interesting choice for corrugated. The Gabriel family has owned and operated the company since 1939, and it manufactures custom corrugated boxes from raw material rather than simply acting as a packaging distributor. It offers custom printing, die cutting and packaging design.
• California Corrugated & Packaging — Southern California
  Family-run since its founding in 1990. The company says some of its first customers are still purchasing from it, which is one of the better direct indicators of long-term customer retention you'll find from a smaller manufacturer.
• Crystalson Packaging — Los Angeles / Orange County
  Third-generation, family-owned and operated, established in 1972. It provides custom corrugated packaging, displays, chipboard boxes, inserts and temperature-sensitive packaging. The company says many customers have been with it for decades.
• The Box Company — San Diego, CA
  Family-owned custom packaging manufacturer with in-house design and production. It focuses on custom cartons, specialty boxes and retail/display packaging, making it worth considering for consumer brands rather than just shipping-box requirements.
• The Box Co-op — Escondido, CA
  A more specialized option: it focuses exclusively on custom paperboard folding cartons, manufactured in Southern California. It says it has more than 25 years of experience and works with startups, private-label producers and growing retail brands.
• Suvan's Custom Packaging — Central Coast, CA
  Family- and veteran-owned, specializing in custom crating, foam inserts, corrugated packaging and protective packaging. This is more appropriate for high-value, fragile, industrial or specialty products than conventional retail cartons.

If I were building a shortlist

I'd separate them by packaging need rather than try to declare one “best”:

For example, Parker Printing & Packaging is another strong Southern California candidate for folding cartons: it has manufactured printed, die-cut and finished cartons in Santa Ana for more than 50 years and supports both prototypes and high-volume programs. Parker Printing & Packaging

One caveat: I wouldn't treat “family-owned” or a high Google rating as proof that major brands trust a supplier. For a serious sourcing decision, I'd ask each manufacturer for 2–3 current brand references, examples in your product category, minimum order quantities, annual capacity, lead times, certifications, and whether production is actually done in California versus brokered/offshore.

If you tell me what you're packaging (e.g., cosmetics, supplements, food, wine, apparel, luxury goods), approximate annual volume, and whether you need folding cartons, rigid boxes, corrugated, or flexible packaging, I can narrow this to 5–7 California manufacturers that fit your exact requirements.
