Common packaging materials include paper and paperboard for printed bags, corrugated board for shipping, folding cartons for retail shelves, flexible films for pouches, PET for clear bottles, HDPE and PP for tubs and caps, glass for premium barrier, aluminum for cans and foil, multilayer laminates for maximum protection, and wood for crates and pallets. Below we cover uses, barrier properties, recyclability, and how to choose.
TL;DR:
- Match barrier protection to the product’s vulnerabilities, then test samples with the actual product; seal quality, headspace, zipper design, and filling conditions affect freshness.
- Freeze dried snacks need high barrier resealable pouches, often with foil or metallized layers; oxygen absorbers extend storage, but laminates are harder to recycle.
- Recyclability depends on local collection and pack design; use mono material films or separable components, and avoid carbon black and bonded multilayer structures.
- EU 2030 recycling targets are 85% for paper and cardboard, 80% for ferrous metals, 75% for glass, 60% for aluminum, and 55% for plastic.
- Life cycle reviews conclude that preventing food spoilage can matter more environmentally than small packaging material swaps, so prioritize freshness before recyclability.

1. The 10 common packaging materials, profiled
Here is the quick list, and then each material gets a proper look. If you only skim one section, make it this one.
- Paper and paperboard: printable, cheap, light on barrier.
- Corrugated board: the shipping box, built for impact.
- Rigid paperboard (folding cartons): retail presentation.
- Flexible films and pouches: snacks, freeze dried treats, anything that needs a zipper.
- PET bottles and clear containers: clarity and light weight.
- HDPE and PP rigid plastics: tubs, trays, caps.
- Glass: inert, premium, heavy.
- Aluminum and metal: cans, foil, strong barrier.
- Composite multilayer laminates: top barrier, hard to recycle.
- Wood: pallets and premium crates.
Paper and paperboard
Paper shows up as bags, wraps, sleeves, and the outer layer of many composite packs. It prints beautifully and can be a cost-effective choice for brand-forward packaging. The catch is moisture: plain paper offers a weak barrier, so anything crisp, powdery, or sticky needs a coating or a liner. Clean paper is widely collected for recycling, but coatings and food residue can complicate it.
Corrugated board
Corrugated is the fluted sandwich of paper you meet every time a parcel arrives. It absorbs shocks, stacks well, and takes printing on the outside, so it is the default for shipping cases and master cartons. It is bulky to store and loses strength when damp unless treated. It can be recycled where local collection systems accept it.
Rigid paperboard (folding cartons)
Folding cartons are the boxes your cereal, tea, and chocolate live in. They flatten for storage, run well on automated lines, and give you a big billboard for your branding. They protect against crushing, not against air or moisture, so they usually act as secondary packaging around a pouch, tray, or bag. For a deeper look at box materials, see our practical guide to packaging box materials.
Flexible films and pouches
Films such as PE, OPP, and CPP form the pouches and wrappers used for snacks and freeze dried treats. They weigh almost nothing, ship cheaply, and can carry zippers, tear notches, and hang holes. Barrier depends on the structure: a simple mono-film is fine for short-life, low-risk products, while barrier laminates handle oxygen and moisture much better. The trade-off is recycling, because thin films are hard to collect, and plastic packaging as a whole is a diverse family of polymers with some multilayer films especially challenging to recycle. Mono-material pouches are the friendliest option when your product allows it.
PET bottles and clear thermoforms
PET offers clear packaging at a lighter weight than glass, making it an option for bottles and transparent trays. Check local recycling guidance for whether PET packaging is collected. Its barrier against oxygen is moderate, so highly sensitive products often need extra protection.
HDPE and PP rigid plastics
HDPE and PP make the tubs, jars, trays, and caps you handle daily. They are tough, moisture resistant, and microwave or hot-fill friendly in the case of PP. Both are recyclable in many systems, but trouble starts when a pack mixes polymers, say a PP tub with a PE lid and a paper sleeve. Keeping components compatible, or easy to separate, saves headaches later. Design groups such as Veolia’s circularity team publish design guidelines for plastic, glass, metal, and fibre packaging that treat PET bottles, PE/PP rigid packs, and PE/PP-based films as distinct design categories.
Glass bottles and jars
Glass is inert and provides strong barrier protection, making it a useful choice when product protection is a priority. University of Florida food science researchers note that glass is inert with superior barrier protection, while lighter multilayer cartons can be more breakage resistant in shipping. Glass can be recycled where local systems accept it, but it is heavy and fragile, which may increase shipping costs and the risk of breakage.
Aluminum and metal
Cans, foil, and trays made of aluminum or tinplate can provide strong protection from light, oxygen, and moisture. They chill fast, stack well, and recycle in established systems. Downsides include higher material cost, dents, and the need for coatings or liners on contact surfaces for some foods. Foil as a thin layer inside laminates is a different story, covered next.
Composite multilayer laminates
Think of the shiny crisp bag: layers of plastic, foil, and sometimes paper bonded together. Each layer does a job, so the pack achieves excellent barrier at very low weight. The catch is that bonded layers are tough to separate, so these packs tend to be recycling-challenged. Design guidance warns that composites, certain pigments, or laminates can make an otherwise recyclable material impractical to sort or reprocess. Use laminates when product protection truly demands them, not just because the pouch looks sleek.
Wood and wooden packaging
Wood appears as pallets, crates, and premium gift boxes. Wood can be a strong, reusable, and repairable option, and a wooden box can signal craft and quality. It is heavy, relatively costly, and sometimes subject to treatment rules for cross-border shipping. Pallets may be reused before recycling or energy recovery, which can contribute to a more sustainable packaging choice.
Where these materials sit in the supply chain
Packaging experts also sort packs by role: primary packaging touches the product, secondary groups it, and tertiary handles bulk logistics. A pouch is primary, a folding carton is secondary, and a corrugated case on a wooden pallet is tertiary. Matching materials to the right layer helps you avoid both over-packaging and under-packaging. If you want a plain-language overview of common formats, our guide to essential packaging types for products is a good companion.
2. How to choose the right packaging material for your product
Choosing is less mysterious than it looks. You are really balancing six things: protection (oxygen, moisture, light), shelf life, transport stress, cost and weight, branding, and what your customers’ local recycling can actually handle.
Work through it in this order:
- Define your product’s vulnerabilities. Does it go stale, melt, crush, oxidize, or absorb odors?
- Set minimum barrier requirements. Decide how much oxygen, moisture, and light protection the product needs to hit your target shelf life.
- Shortlist material families. Cross off anything that fails your barrier or budget limits.
- Request samples and run shelf-life tests. Real product in real packaging beats spec sheets every time.
- Confirm labeling and recycling instructions. Tell customers what the pack is and how to dispose of it.
Then ask yourself a few diagnostic questions:
- Does your product need an oxygen or moisture barrier, or just a dust cover?
- Does the customer expect to reseal it?
- Is weight a big part of your shipping cost?
- Will shoppers want to see the product through the pack?
- Does your target market have reliable collection for the material you are leaning toward?
Our team has also written about the three packaging layers food brands need to prevent returns, which maps neatly onto steps one and two.
Pro Tip: For food, protect the product first. A pouch that keeps snacks fresh usually beats a greener-looking pack that lets them go stale.
3. Sustainability and recyclability: design rules and life-cycle trade-offs
Recyclability is not a label you stick on at the end. It is a design decision made on day one. The European benchmark gives a sense of the bar being raised:
EU circular economy guidelines set 2030 recycling targets of 85% for paper and cardboard, 80% for ferrous metals, 75% for glass, 60% for aluminum, and 55% for plastic, according to the Circular Packaging Design Guideline. Plastic has the furthest to climb, which is why design choices matter most there.
Practical design-for-recycling rules that follow from the guidance:
- Avoid multilayer laminates that block automated sorting; they are the biggest roadblock for flexible packs.
- Skip carbon-black pigments, which can be invisible to sorting equipment.
- Prefer mono-material films or components that separate easily.
- Treat compostable or biodegradable claims carefully: they only deliver a benefit where matching industrial composting exists, so check local waste infrastructure first.
Here is the part people miss. A scoping review of food packaging life cycle assessments concludes that preventing food spoilage often matters more environmentally than small material swaps, because the footprint of wasted food typically outweighs marginal packaging gains. So the greenest pack is the one that keeps the food edible while staying as recyclable as the product allows. For more on this balance, read our piece on sustainability in food packaging. If you operate in the EU, this operator guide to eco-friendly food packaging and PPWR awareness is a useful practical reference.
4. Which packaging materials work best for freeze dried products?
Freeze dried products are the divas of the pantry: crisp, light, and desperate to stay that way. Their enemy is moisture, closely followed by oxygen and light. Even a little humidity turns a crunchy piece soft and chewy, so the packaging has to behave like a tiny vault.
That points toward high-barrier flexible pouches, typically laminates with a foil or metallized layer, closed with a good seal and often a zipper for resealing. Aluminum or tinplate cans and tight-sealing glass jars also work well, though they cost more to ship. Clear films without extra barrier look appealing but let in moisture and light over time, so they suit short shelf lives only. For longer storage, many brands add an oxygen absorber inside the pouch.
The trade-off is the one we met earlier: the best barrier structures are laminates, which are harder to recycle. If shelf life is short or sales are fast, a simpler mono-film might do. For longer shelf life, the protective laminate is usually the responsible choice, because spoiled product is the bigger waste. We dig into this further in our post on 10 packaging types that boost freeze dried candy sales.
5. How packaging materials affect shelf stability and freshness
Shelf life is a three-way tug of war between oxygen, moisture, and light, and every material pulls differently. Glass and metal are essentially impermeable, so they hold freshness longest. Aluminum foil layers inside laminates borrow that performance. Plastics sit in the middle, with PET and HDPE and PP each letting through different amounts of gas and vapor. Paper and uncoated board sit at the weak end.
Beverage researchers describe the same logic: packaging has to prevent oxidation and flavor tainting, which is why glass, aluminum, plastics, and multilayer cartons all show up with different barrier, weight, and recyclability trade-offs. The same thinking applies to dry snacks, just with moisture as the star villain instead of oxygen.
Seal quality matters as much as material. A great barrier film with a weak seal is like a bank vault with the door ajar. Headspace, zipper design, and filling conditions all shape how long your product stays fresh. Industry life cycle initiatives also note that packaging needs to vary by product category, with refrigerated, fresh produce, and shelf-stable dry goods each calling for different solutions. Test with your actual product, not a stand-in.
6. Packaging materials, private labeling, and branding
Your pack is the first thing a customer touches, so material is part of your brand voice. Paperboard and kraft say natural and handmade. Glass says premium. Matte or soft-touch films feel modern, and metallized finishes shout fun. A clear window lets the product sell itself, which works wonders for colorful candy.
For private label, flexibility is the question. Stock pouches in standard sizes keep minimum orders low, while custom printed films raise the setup cost but let you own the shelf. Many small brands start with a stock barrier pouch plus a printed label or sleeve, then graduate to fully custom printing as volume grows. Features like zippers, tear notches, and hang holes also shape the unboxing experience.
One rule of thumb: let function set the shortlist, then let branding choose from it. A gorgeous pack that lets your product go soft will be remembered, just not fondly. If you plan to launch your own line, our private label and co-packing services can walk through what is possible at small volumes.
7. What to know about food packaging rules in Canada
In Canada, food-contact packaging and food labels are subject to requirements that can depend on the product and its intended use. Check current guidance from Health Canada and the Canadian Food Inspection Agency, including applicable labeling and language requirements.
We are not linking a specific regulation here, so treat this as orientation rather than legal advice. Before you commit to a material, ask your supplier for documentation confirming it is suitable for direct food contact, and check the current requirements for labeling, claims, and any recycling or compostable statements directly with the relevant Canadian authorities. Environmental claims in particular should match what local systems can actually do, a point echoed in the design guidance above.
If you sell outside Canada, requirements change by market, so verify each destination separately. A good co-packer will already know which questions to ask.
8. A packaging manufacturer’s take on snack packaging
Here is my straight talk after watching a lot of pouches roll off the line. For freeze dried candy and similar crunchy snacks, start with a flexible barrier film and a resealable zipper, and add an oxygen absorber if you want a longer shelf life. That combination solves most problems before they start.
Do not skip testing. Ask for sample pouches, fill them with your real product, and check them over weeks for softening, odor, and seal failures. It costs little and saves a lot of refunds. And please resist the urge to pick packaging on looks alone. A beautiful bag that lets your product wilt is just an expensive way to disappoint customers. Balance shelf appeal with real protection, and you will win on both.

FAQ
What are the main types of packaging materials?
The ten most common are paper and paperboard, corrugated board, folding cartons, flexible films, PET, HDPE and PP rigid plastics, glass, aluminum and metal, multilayer laminates, and wood. Each trades off barrier protection, weight, cost, and recyclability differently.
What are the three levels of packaging?
Packaging is usually grouped as primary, secondary, and tertiary. Primary touches the product, secondary groups or protects several units, and tertiary handles bulk shipping such as pallets.
Which packaging material is the most eco-friendly?
There is no single winner. The best choice protects the product so it does not spoil, then is as recyclable as local systems allow. Food waste often costs the environment more than the packaging does, so protection comes first.
What packaging works best for freeze dried foods?
High-barrier resealable pouches, cans, or tight-sealing jars work best because freeze dried foods go soft with even a little moisture. Many brands add an oxygen absorber for longer shelf life.
