Food Packaging Materials 101: What Every Business Should Know

Direct vs Indirect Food Contact

The first question to ask is whether the food touches the material. The answer shapes which materials and which rules apply.

• Direct contact. The food touches the board, the paper or the coating. Examples are a burger in a paper wrap, fries in a paper cone or a pizza on a box lid. The material must be suitable for food, and any coating, ink or adhesive that can touch the food has to be too.
• Indirect contact. Another layer sits between the food and the board. Examples are cereal in an inner bag inside a carton, or candy in a foil wrapper inside a box. The outer pack still matters, but the inner layer does the contact work.

Many food packs are a mix: a printed carton on the outside, a liner on the inside, and a plastic or foil layer where a barrier is needed. When you ask a supplier for a quote, say which parts of the pack the food will touch.

Common Food Packaging Materials

The table sums up the materials you will meet most often. Each one is a trade-off between cost, protection, look and end of life.

Paper-Based Materials

Paper-based packaging is the common choice for takeaway, bakery, confectionery and dry food. Paperboard prints in full color and folds into cartons, sleeves and gable boxes. Corrugated board is stronger and insulating, so it is used for pizza and takeaway boxes and for outer shipping cartons. Plain paper is not a barrier to oil or water, so many paper food packs add a liner, a grease-resistant paper or a thin coating. See our food packaging range, gable boxes, pillow boxes and folding cartons.

Greaseproof and Wrapping Papers

Greaseproof paper is a dense paper that stops oil from soaking through. It is used to wrap burgers and sandwiches and to line baskets and boxes for fried food and pastries. How the paper resists oil depends on the paper and its treatment, so ask your supplier. Our greaseproof paper page explains what to consider.

Plastics

Plastics give some of the strongest barriers at low weight, and they can be clear so the food shows. Common types in food packaging are PET (bottles and clear trays), PP (tubs and microwaveable containers), PE (films and bags) and PS (clamshells and cups). Plastics are the usual choice for wet, fresh or long-life foods. The trade-off is end of life: recycling depends on the type and on local programs.

Aluminum, Glass and Metal

These are the heavy, high-barrier options. Aluminum foil blocks light, air and moisture, which is why snacks and chocolate use it. Glass is inert and reusable but heavy and breakable. Metal tins and cans last on a shelf for a long time and are widely recycled. They cost more to ship and to make than paper.

Compostable and Plant-Based Materials

Some food packs use plant-based plastics or fiber materials such as bagasse and molded pulp. They can suit events and food service where waste is collected for composting. They need a real composting route to deliver any benefit. Our guide to biodegradable packaging materials explains the terms.

How to Choose by Food Type

Use this as a starting point. Each food asks something different of the pack.

Dry Foods

Cereal, crackers, nuts and snacks need protection from moisture and air so they stay crisp. A paperboard carton looks good on a shelf, but it is the inner bag or liner that does the barrier work. For long shelf life, ask about a barrier film.

Greasy and Oily Foods

Fries, fried chicken, pastries and burgers leave oil on the pack. Greaseproof paper, a grease-resistant liner or a coated board stops it soaking through and staining the outside. Tell your supplier how oily the food is.

Hot Foods

Hot meals give off steam. A tightly closed box keeps heat in but can make crisp food soggy, so vents help. Corrugated board insulates and keeps its shape. Check that any coating or liner suits the temperature.

Cold and Frozen Foods

Condensation can soften plain board. Moisture-resistant board or a coating helps. For frozen food, ask the supplier what the pack is rated for.

Liquids and Wet Foods

Sauces, soups and drinks need a leak-proof layer: a sealed liner, a coated cup, a pouch or a rigid container. Plain board alone will soak through.

Barrier Needs and Shelf Life

A barrier is what stops something getting in or out of the pack. Four things matter most.

• Moisture. Too much and the food goes soft or moldy; too little and it dries out.
• Oxygen. Air makes fats go stale and spoils many foods.
• Light. Light can fade color and affect flavor.
• Grease. Oil can soak through paper and stain the outside.

How strong the barrier has to be depends on shelf life. A bakery item eaten the same day needs a clean, grease-resistant wrap, and a snack on a shelf for months needs a high-barrier layer. Packaging does not make food last forever. Storage, temperature and the food itself matter just as much. If shelf life is critical, test the real food in the real pack.

Takeaway vs Retail Packaging

Takeaway and retail packs do different jobs.

For takeaway ideas, see our takeaway boxes and paper cones. For shelf-ready packs, see our tuck boxes and our industry pages on bakery boxes, candy and chocolate boxes and coffee and tea boxes.

Labeling and Regulations to Check

Food packaging is regulated, and the rules depend on where you sell. The points below are general starting points, not legal advice. Check the rules for your market and, if needed, ask a food-safety adviser.

• Food-contact rules. Materials that touch food must be suitable for that use. In the United States, the Food and Drug Administration regulates substances used in food contact. The European Union and other regions have their own frameworks.
• Chemical restrictions. Some US states restrict certain chemicals, such as PFAS, in food packaging. Ask the supplier for a statement about the materials and coatings used.
• Labeling. Packaged food usually has to show things such as the name of the food, ingredients, allergens, net quantity and the producer's details. Rules differ by country and by product.
• Claims. Words such as "organic", "natural" or "recyclable" can be regulated, so use them only if you can back them up.
• Facility and process rules. If you produce food, the place you make and pack it may have its own requirements.

Whatever you need, get it in writing from the supplier, and keep the document. If you need a certificate or a statement for a pack, tell us which one and we will confirm whether we can supply it.

Sustainability Trade-Offs in Food Packaging

Packaging has an environmental cost, and so does wasted food. Often the second is bigger, so a pack that keeps food fresh for longer can be the greener choice even if it uses more material. The right balance depends on the food.

• Paper-based packs are widely recycled when clean, but food and grease contaminate paper, and coatings can make recycling harder. See our guide on whether cardboard gets recycled.
• Plastic has strong barriers and low weight, but recycling depends on the type and the program.
• Compostable packs only help where composting collection accepts them.
• Reusable packs, such as tins and glass jars, last longer but cost more to ship.
• Right-sizing the pack saves material in every case.

What We Can Do for Food Packaging

We make food packaging printed with your brand, including takeaway boxes, paper cones, gable boxes, paper bags, folding cartons, cups, lids and greaseproof paper. Our boxes are paper-based: paperboard in white or brown kraft, and corrugated board for mailers and shipping boxes. We do not make claims about food-safety certification on this page. Tell us the food, how it is packed, whether it touches the board, whether it is hot or cold and how long it must last, and we confirm what is possible and send a quote.

Examples

These are examples to show the thinking, not case studies.

A Bakery Selling Cookies

Cookies are dry, a little oily and eaten within days. A paperboard box with a greaseproof liner or a window with a food-grade film, plus a paper bag for carrying, fits the job. Keep the print simple and check the grease resistance with real cookies.

A Takeaway Restaurant

Hot meals need steam to escape and sauces to stay put. A sturdy takeaway box with a vent and a liner, and a paper bag with a handle for delivery, works well. Test stacking and a ten-minute ride in a delivery bag.

A Snack Brand on a Retail Shelf

A snack may need months of shelf life, so the barrier is the inner film or foil layer. A printed carton on the outside carries the brand and the label. Ask the supplier how the carton and the inner pack work together.

A Checklist for Choosing Food Packaging

• I know whether the food is dry, greasy, hot, cold or liquid.
• I know whether the food touches the board or an inner layer does.
• I know the shelf life I need and how the pack will be stored.
• I checked the food-contact, chemical and labeling rules for my market.
• I asked my supplier for written confirmation of what I need.
• I tested the real food in a sample of the pack.
• I measured the pack to fit the food. Our measuring guide shows how.

Common Mistakes

• Using plain paperboard for oily or wet food with no liner.
• Not telling the supplier that the food touches the board.
• Skipping a test with the real food.
• Assuming a pack that is fine in one country meets the rules in another.
• Choosing a pack for looks and ignoring the barrier.
• Making environmental claims on the pack that you cannot document.
