Packaging Materials: The Complete Guide to Box Stocks
The stock is what your box is made of. It sets how strong it is, how it prints, how luxe it feels, how green it is, and how much it costs.
It is a separate pick from the box style (the shape). The same mailer can be made in a range of stocks. This guide covers every stock you will pick from – the four main ones plus the specialty and eco picks. You get weights, eco notes, cost, and a clear way to pick. All are open on our custom printed boxes for any product with no die or plate fees.
Key takeaways
- Cardstock (SBS) – bright and printable; the standard for retail cartons.
- Kraft – natural, easy to recycle, and economical.
- Corrugated – strong and protective; made for shipping.
- Rigid – thick and luxurious; for premium and gift products.
- Specialty & eco – recycled, FSC, food-grade, and molded fiber for specific needs.
What is a packaging material, exactly?
A packaging stock is the sheet your box is cut, folded, and printed from. Most custom boxes use paper. They differ in three ways.
The fibers and how they are bleached set the color and print top. The plies or thickness set strength and feel. Any coat or flute sets guard. Get those three right and the box looks luxe, guards the goods, and costs no more than it needs to.
What is cardstock (SBS paperboard)?
Cardstock – often SBS, or solid bleached sulfate – is a smooth, bright-white paperboard. It takes vivid print well. That is why it is the go-to for retail folding cartons: beauty, supplements, packaged foods, and more.
It is light, ships flat, and is the cheapest stock at higher counts. Food-safe versions work for direct food contact.
Best for: retail shelf products and large-run runs. Common in folding cartons for retail products and custom printed cosmetic boxes. Deep dive: SBS cardstock guide.
What is kraft?
Kraft is an unbleached paperboard with a natural brown look and high tear strength. It is easy to recycle, often made with recycled content, and signals an honest, eco brand. That is why it is a hit with organic, artisan, and refill-first brands.
It prints well in an earthy palette. A white under-print lets bright colors pop on the brown stock.
Best for: natural and green brands. See kraft boxes for natural brands and custom kraft paper for packaging; deep dive: kraft paperboard guide.
What is corrugated?
Corrugated board has a wavy, fluted layer between flat liners. That flute gives it strength and cushion. Great for shipping.
It is the stock behind strong shipping boxes and online mailers. It guards heavy or fragile goods in transit. It is also widely easy to recycle. Most day-to-day “cardboard boxes” for shipping are corrugated.
Best for: shipping, heavy items, and protective outer boxes. See strong corrugated shipping boxes, easy to recycle cardboard shipping boxes, and mailer boxes for online shipping; deep dive: corrugated and shipping boxes guide.
What is rigid chipboard?
Rigid board (thick chipboard wrapped in printed paper) is the heavy pick. It does not fold flat. It ships pre-formed. That is what gives it a solid, luxe feel.
It is the top-tier stock, and the priciest. It is saved for goods where the unboxing is part of the value. Think magnetic-close and two-piece gift boxes.
Best for: luxury, gifting, and high price points. See premium rigid gift boxes and magnetic closure gift boxes.
What specialty and eco materials are there?
Beyond the four main stocks, a few specialty picks solve set needs:
- Recycled-content board – SBS or kraft made with used-fiber recycled fiber to cut virgin material, with the same print quality.
- FSC-backed stock – well-sourced paper for brands that want a recognized seal on the box.
- Food-grade board – SBS and kraft rated for direct food contact, with grease-safe options for bakery and oily foods. See our food-safe packaging guide.
- Molded fiber / paper pulp – for protective inserts and trays that are easy to recycle and compost-ready, an alternative to foam.
- Window film (PET or PVC) – a clear patch over a die-cut opening so shoppers see the product. PET is a common food-safe pick.
Quick comparison
| Material | Strength | Feel | Best for |
|---|---|---|---|
| Cardstock (SBS) | Light–medium | Smooth, bright | Retail cartons |
| Kraft | Medium | Natural, textured | Eco & artisan brands |
| Corrugated | High | Sturdy, plain and tough | Shipping & heavy goods |
| Rigid chipboard | high | Solid, luxurious | Premium & gifting |
Cardboard vs. corrugated: what's the difference?
People use “cardboard” for almost any paper box, but it is a loose term. In real life, a thin printed retail box is paperboard (cardstock). A strong shipping box is corrugated. That is the one with the fluted inner layer. If a box needs to live through the mail, you want corrugated.
Which material should you choose?
Three questions point you to the answer:
- Does it ship on its own? If yes, lean corrugated for protection.
- Is it sold on a shelf? Cardstock prints the brightest for retail.
- How premium is it? Rigid for luxury; kraft for natural and economical.

How do weight, thickness, and grades work?
Each stock comes in a range of thickness. It changes both the feel and the cost. Paperboard is measured in caliper (points, where 1 pt = 0.001 inch) or GSM (grams per square meter). A heavier board feels more solid. But it costs more and adds shipping weight.
Corrugated is graded by flute. Big flutes (like C) give more cushion and stack strength. Fine flutes (like E and F) give a smoother top for print. It is also graded by single- vs double-wall build for heavier loads. We pick the right weight for your product. So it feels right without over-paying. Full breakdown: paper weights and thickness explained.
Coated or uncoated stock?
One choice quietly shapes the whole look of a box. That choice: coated or uncoated stock. A coated board has a thin clay layer on top. It holds ink on top of the paper instead of letting it soak in.
That gives you sharper edges, deeper color, and a slight sheen. It is why bright retail cartons most often start from a coated one-side (C1S) or two-side (C2S) sheet.
An uncoated board has no such layer. So ink soaks in for a softer, flatter, more hand-feel look. That is the natural look most people link to kraft and to top-tier clean brands. Uncoated stock is also easier to write or stamp on. That helps for boxes that get hand-labeled or dated.
Neither is better in the abstract. Coated wins when you need punchy photo color and a wipe-safe surface. Uncoated wins when you want a warm, quiet, hand-made feel. If you are not sure, tell us how the box should feel in the hand. We will steer the stock to match.
How does material affect printing and finishes?
The stock is the canvas. So it shapes how finishes land. Bright SBS holds the sharpest full-color CMYK and Pantone print. It also shows foil, spot UV, and embossing clearly.
Kraft mutes color. A white under-print brings back the pop. It pairs well with a matte, hand-made look. Corrugated takes good print on fine flutes. But it fits bold, simple art best.
Rigid board carries the richest finishes – soft-touch, foil, and deep emboss – because the top is wrapped printed paper. See our box finishes guide for what each finish does.
Which material fits each industry and use case?
| Industry / use | Common material | Why |
|---|---|---|
| Cosmetics & beauty | SBS cardstock | Bright, crisp color for shelf and PR – see cosmetic boxes for beauty brands |
| Food & bakery | Food-grade SBS or kraft | Direct-contact safe, grease-safe options – see food-safe boxes for direct contact |

| CBD & supplements | SBS or kraft | Panel space for compliance copy – see CBD packaging with compliance panels |
How green is each material?
All paper stocks are easy to recycle, but they differ. Uncoated kraft and SBS are curbside easy to recycle and breaks down. Corrugated is one of the most-recycled stocks in the US and has high recycled content.
Recycled-content and FSC-backed boards let you make a solid sourcing claim. Molded fiber inserts swap out foam for a fully easy to recycle build. Heavy lamination and mixed stocks cut recycling, so for an eco run keep coats light and pick soy-based inks. Compare end-of-life options in our easy to recycle vs compost-ready guide and our green packaging guide.
What does each material cost?
From cheapest to priciest at the same size: kraft and SBS cardstock are the most low-cost and ship flat. Corrugated costs a bit more for the extra board and bulk. Rigid is the priciest. It is thick and mostly hand-built.
The bigger cost levers are count (price drops fast with volume), finishes, and inserts – not just the base stock. We never charge die, plate, or set-up fees. So switching to a custom size or shape does not add tool cost. See the full breakdown in our packaging cost guide.
Should you test the material before you commit?
A screen can never fully show how a stock will feel or how heavy it reads in the hand. It also can not show how a color sits on brown kraft vs bright white board. So put the real stock in front of you before a full run.
The easy way: ask for a plain sample of the stock and weight you want. Hold it, fold it, and see how it holds a crease. If color match or a finish matters – a foil touch, a soft-touch coat, a set Pantone – ask for a printed proof on the real run stock, not a stock swatch. The same ink looks quite different on coated, uncoated, and kraft.
It also helps to think through the box’s whole trip. A carton that just sits on a shelf can be lighter than one tossed in a mailbag, held by carriers, and maybe reused by the buyer. Share those points up front. We will pick a weight that lives through the trip without paying for board you do not need.
What common material mistakes should you avoid?
- Using paperboard for shipping. A pretty SBS carton will show up crushed if mailed on its own. Ship it inside corrugated.
- Over-speccing rigid. Rigid is gorgeous but costly; many "premium" looks are in reach with SBS plus a soft-touch and foil finish.
- Forgetting food-grade. Direct food contact needs a food-grade board and inks – standard stock is not on its own food-safe.
- Heavy lamination on an "eco" box. A thick plastic laminate can make a kraft box non-easy to recycle, cutting the message.
- Printing bright color on raw kraft. Without a white under-print, colors look muddy on brown stock.
What are the expert tips?
- Match the stock weight to the product weight. A light product in heavy board wastes money and shipping.
- Order a real sample of the stock and finish before a large run. Screens lie about feel and color.
- For a green claim, lead with the material (kraft/recycled/FSC) and keep the finishes easy to recycle.
- If you ship and sell on a shelf, use two stocks: a corrugated shipper around a printed retail carton.

Frequently asked questions about packaging materials
What is SBS cardstock?
SBS (solid bleached sulfate) is a smooth, bright-white paperboard that prints vividly. It is the standard material for retail folding cartons, with food-grade versions available.
Is kraft or corrugated stronger?
Corrugated is stronger thanks to its fluted layer, which is why it is used for shipping. Kraft paperboard is sturdy for cartons and wraps but is not built for heavy shipping on its own.
What do GSM, points, and caliper mean?
They all describe how thick or heavy a board is. GSM is grams per square meter, while points and caliper measure thickness in thousandths of an inch. A higher number means a heavier, more solid board that costs and weighs more.
Which packaging material is cheapest?
Kraft and SBS cardstock are the most economical per unit and ship flat. Corrugated costs a little more for the extra board, and rigid chipboard is the most expensive because it is thick and hand-built. Quantity affects price more than the base stock.
Which packaging material is most eco-friendly?
Kraft and recycled paperboard are common green choices, and corrugated is highly easy to recycle. Keep coatings minimal and choose soy-based inks to keep a box easy to recycle – see our green packaging guide.
Can I combine two materials for one product?
Yes, and many brands do. A common setup is a printed SBS or kraft retail carton shipped inside a corrugated mailer, so you get shelf appeal and shipping protection together.
Are your boards food-safe?
We offer food-grade SBS and kraft rated for direct food contact, with grease-safe options for bakery and oily foods. Standard stock is not on its own food-safe, so confirm food-grade for eaten products.
Can you print on all of these materials?
Yes. We print full color on cardstock, kraft, corrugated, and rigid board, with Pantone matching and finishes available on each.
Why is packaging material choice so important for a product launch?
Because the wrong material either damages your product or damages your brand. Ship a fragile jar in a folding carton alone and it arrives broken. Wrap a prestige serum in single-wall corrugated and it reads cheap. The material sets sturdiness, print quality, shelf feel, freight cost, and eco story. Get it right up front and you save on returns, complaints, and design rework across every reorder.
How do I choose the right packaging material for my product?
Answer three questions. What is the product weight and fragility? – light retail = paperboard, heavy or fragile = corrugated, prestige hero = rigid. How does it ship? – DTC alone needs a shipper-grade outer, wholesale in master cartons can use a lighter retail carton.
What is the price point and shelf? – premium finishes need smooth SBS or rigid; natural clean-beauty suits kraft. Tell us those three and we spec a material.
Which packaging material is best for e-commerce shipping?
Corrugated, in almost every case. The fluted middle layer soaks up shock and stack pressure that flat paperboard or kraft cannot. Single-wall corrugated handles most light-to-medium DTC orders. Double-wall (BC or AC flute) handles heavy or fragile. Many brands run a printed folding carton for shelf appeal inside a plain corrugated shipper for the mile-long trip through carriers.
What are the 4 types of packaging material?
The four main packaging-material families are paper and paperboard (SBS cardstock, kraft, corrugated, rigid chipboard — the dominant family for folding cartons and shipping), plastic (PET, HDPE, PP, LDPE, PCR plastics — used for bottles, jars, pouches, films, and clamshells), glass (used for bottles, jars, and prestige cosmetic primary packaging), and metal (aluminum tubes, tinplate cans, steel aerosols — used for food cans, drink cans, cosmetic tubes).
Secondary and tertiary families include wood (crates, pallets), textile (fabric wraps, cotton drawstring bags), and bioplastics (PLA, PHA). Most retail packaging combines two or three materials: paper outer carton, plastic or glass primary, and a thin plastic or wax inner liner.
What is mono-material packaging?
Mono-material packaging is packaging made entirely from a single material family (all PE, all PP, all paper, all aluminum) so it enters a single recycling stream without separation. It’s the opposite of multi-material composites (foil-lined plastic pouches, plastic-laminated paperboard) that are technically recyclable but almost never are in practice.
Mono-material has become a 2024–2026 compliance target for brands selling into the EU under PPWR (Packaging and Packaging Waste Regulation) and California under SB 54. Common mono-material formats: all-paper (uncoated SBS or kraft with water-based coating), all-PE pouches (replacing PE/PET laminates), all-aluminum tubes with aluminum caps.
What is secondary packaging material?
Secondary packaging is the layer that groups and protects primary packaging — the printed carton around a cosmetic bottle, the shrink wrap around a 12-pack of soda cans, the display tray that holds 24 lip balms on a shelf. Primary packaging touches the product directly; secondary packaging holds primary units together for shipping, display, or multi-pack sale; tertiary packaging (shipping cases, pallets, stretch wrap) holds secondary units for freight.
Common secondary materials: paperboard folding cartons, corrugated display trays, printed sleeves, and shrink-wrap collations.
What is rigid packaging material?
Rigid packaging material is any packaging that holds its shape without external support — glass bottles, aluminum cans, HDPE jars, PET bottles, metal tins, and rigid chipboard boxes. It’s the opposite of flexible packaging (pouches, films, bags, wraps) that collapses when empty.
Rigid packaging offers better product protection, stackability, and premium shelf feel; flexible packaging offers lower material weight, lower freight cost, and typically lower unit cost. The 2026 trend is "rigid where premium matters, flexible where cost and sustainability matter."
What is transport packaging material?
Transport packaging — also called tertiary packaging — is the shipping-stage packaging that moves retail-ready units from producer to retailer or end buyer. Common transport materials: double-wall corrugated shipping cases, wooden pallets, stretch wrap, strapping, edge protectors, and void-fill (air pillows, kraft paper, molded pulp).
It’s functional, rarely printed, and is almost always recycled or returned to the supply chain. For e-commerce, transport packaging doubles as the unboxing experience, so DTC brands often upgrade the corrugated shipper with 1-color inside print or a branded tape.
Which packaging material is most sustainable?
Uncoated kraft paperboard with water-based coating and soy-based inks is the single most-recyclable, lowest-impact option for retail cartons — it enters curbside paper streams, has 50–100% recycled content options, and biodegrades if it escapes the recycling loop.
For primary containers, aluminum and glass have the highest recycling rates (aluminum ~75%, glass ~33% in the US) but higher freight carbon than plastic. The 2026 consensus: ranked by typical lifecycle impact for retail packaging, from lowest to highest: paper < aluminum < PCR plastic < glass < virgin plastic < multi-material composite. "Most sustainable" also depends on how the shopper disposes of it — the greenest material in a landfill performs worse than the second-greenest in a recycling bin.
What is the cheapest packaging material?
Thin kraft paperboard (200–300 GSM, uncoated) and single-wall corrugated are the cheapest commercially-available packaging materials by raw stock cost — typically $0.08–$0.30 per retail-sized carton at 1,000-unit runs. Flexible plastic films (LDPE poly mailers) run even lower on a per-unit basis ($0.05–$0.20) but have higher environmental cost.
In practice at the 100–500 unit MOQ, the difference between "cheapest" (kraft) and "mid-priced" (SBS with CMYK print) is often 10–20% of total unit cost once you factor in printing, tooling, and finishing — so brands rarely optimize for raw-stock cost alone.
How do you calculate packaging material cost?
Four inputs: (1) flat sheet size — the unfolded dieline dimensions (e.g., 24 × 18 inches for a 6 × 4 × 3-inch tuck-end carton), (2) stock cost per square meter or thousand sheets — from the paperboard supplier, (3) sheet yield — how many cartons fit on a parent sheet (reduces waste), and (4) print + finish + die-cut + assembly cost — typically 60–80% of total unit cost.
Formula: unit material cost = (flat sheet area × stock cost per sq.m) / sheet yield. Total unit cost = unit material + unit print + unit finish + unit assembly + tooling amortized. At PV we quote all-in (no tooling split-out) so the quote is directly comparable to competitors with die/plate/setup fees.
See our packaging cost guide.
How do you calculate GSM of packaging material?
GSM (grams per square meter) is measured by weighing a cut sample of known area and scaling. Standard lab method: cut a 10 × 10 cm (0.01 sq.m) sample on a precision cutter, weigh on a 0.001 g scale, multiply the weight in grams by 100 to get GSM.
Example: a 10 × 10 cm sample weighing 3.5 g is 350 GSM paperboard. Field method without a scale: GSM ≈ caliper (in mm) × density (0.7–0.8 for typical SBS and kraft) × 1,000. A 0.5 mm board at 0.75 density ≈ 375 GSM.
See our paper weights and thickness guide.
What is the best packaging material for soap?
Printed kraft paperboard (300–350 GSM) for the outer carton with a cold-process-cure-friendly sleeve or shrink band on bare bars. Kraft reads artisan, is curbside-recyclable, and photographs cleanly for Instagram and Shopify. For moisture-sensitive soaps (cold-process, M&P with glycerin), add a thin wax-paper inner wrap or a food-grade PE lining.
Fragrance-forward and luxury bars often move to SBS with foil or soft-touch; cold-process indies dominate kraft. See our soap packaging guide.
What is the hard glossy packaging material?
The hard, glossy packaging material people usually mean is coated SBS paperboard (C1S or C2S) or UV-coated paperboard — smooth white stock with a clay or UV-cured coating that reflects light sharply and holds vivid print. Alternative hard-glossy formats: injection-molded ABS or acrylic (used for high-end cosmetic jars and compacts), rigid chipboard wrapped in gloss-laminated paper (used for prestige gift boxes), and tinplate steel with a gloss lacquer (used for cookie tins and gift boxes).
Why is cardboard a good packaging material?
Six reasons cardboard dominates packaging: (1) recyclable at curbside in >95% of US municipalities, (2) biodegradable if it escapes the recycling loop, (3) renewable from sustainably-managed forests (FSC-certified sources), (4) printable at high resolution for CMYK and Pantone, (5) die-cuttable into virtually any shape with no tooling cost at PV, and (6) economical — cheapest retail-ready substrate by a wide margin.
The limitation: no moisture or oil barrier without added coating.
Which packaging material is best for biscuits (cookies)?
Food-grade SBS paperboard (350–400 GSM) with a grease-resistant PFAS-free coating and an optional window film. For export, add a food-grade PET inner tray or an aluminum-foil moisture barrier bag inside the carton. Cookie packaging has to resist crumbs, oil (butter, chocolate), and crush pressure in transit — so most commercial cookie packaging is layered: outer printed carton, inner food-grade tray, optional moisture barrier.
What is plastic packaging material?
Plastic packaging material covers several families: PET (polyethylene terephthalate — soda bottles, cosmetic bottles, clamshells), HDPE (high-density polyethylene — milk jugs, detergent bottles, cosmetic jars), LDPE (low-density polyethylene — poly mailers, shrink wrap, bags), PP (polypropylene — yogurt cups, bottle caps, flexible pouches), PS (polystyrene — foam clamshells, cups — being phased out), PVC (vinyl — limited to specialty use), and bioplastics (PLA, PHA — compostable alternatives for cups and films).
PCR versions of PET, HDPE, and PP are commercially available at 30–100% recycled content.
What is the most common packaging material used?
By weight, corrugated cardboard is the single most-used packaging material globally — dominant for shipping, retail-ready display, and e-commerce. By unit count, flexible plastic films (poly mailers, pouches, wraps) edge out paper for sheer volume of individual units.
For retail cartons specifically, SBS cardstock and kraft paperboard dominate — folding cartons remain the standard retail format for cosmetics, food, supplements, and consumer electronics.
What packaging material is recyclable?
Readily recyclable in US curbside streams: uncoated paper and paperboard (SBS, kraft, corrugated), aluminum, steel/tinplate, PET #1, HDPE #2, and glass (where accepted). Harder to recycle: PP #5 (accepted in <50% of municipalities), LDPE #4 films (require drop-off), multi-material composites (plastic-laminated paperboard, foil-lined pouches).
Non-recyclable in most streams: PS #6 foam, mixed plastics #7, metalized films. For a verifiable "recyclable" claim under FTC Green Guides, confirm the specific material and that it’s accepted in a substantial majority of US recycling programs.
How do you recycle packaging material?
Three steps per material family: paper and paperboard — flatten the box, remove tape and labels, place in curbside paper or cardboard bin; plastic — rinse the container, replace the cap (modern facilities now accept caps-on), place in curbside recycling bin, follow local plastic-code rules; glass — rinse, remove non-glass lids, place in curbside glass bin where accepted (many US cities no longer accept glass curbside); metal — rinse aluminum and steel cans, crush if practical, place in curbside metal bin.
Multi-material composites (foil pouches, laminated cartons) usually must go to specialty drop-off programs like TerraCycle.
How do you choose packaging material for a product?
Six questions: (1) Does it ship on its own? → corrugated outer. (2) Is it displayed on a shelf? → printed SBS or kraft carton. (3) Does it contain food or cosmetics touching product directly? → food-grade or MoCRA-compliant stock. (4) What’s the price point? → rigid for premium, SBS for mid, kraft for value/eco. (5) What’s the sustainability goal? → kraft or FSC-certified SBS, mono-material, water-based coatings. (6) What’s the volume? → low MOQ favors paper (no plastic-mold tooling); high MOQ opens up injection-molded plastic and glass.
Share the answers on your quote request and we’ll spec a material.
How do you overcome packaging material shortages?
Three practical moves when supply chain tightens: (1) Substitute within a material family — swap kraft for recycled SBS, swap virgin PET for PCR PET, swap single-wall corrugated for double-wall. (2) Build 2–4 weeks of safety stock on your highest-volume SKU dielines so a 2-week shortage doesn’t stock-out customer-facing SKUs. (3) Diversify suppliers — qualify a second packaging supplier on your top SKU so a single-supplier outage doesn’t halt production.
US-based suppliers like PV typically have shorter supply chains and are less exposed to overseas freight disruption than import-dependent competitors.
