Food packaging does much more than hold a product—it protects the food you eat, keeps it safe during transport, slows spoilage, and helps shoppers trust a brand. Good packaging can extend shelf life, prevent contamination, and keep flavors and textures fresh. It also affects how people see your product on the shelf, from quality and sustainability to overall brand image.
In this guide, we’ll walk through the key functions of food packaging, the most common material types, and how to choose the right option for your product. Whether you’re a food manufacturer, brand owner, or packaging buyer, these insights will help you make smarter decisions.
Key Functions of Food Packaging Materials
Food packaging does far more than simply hold a product. It plays several roles that protect food quality and support the entire supply chain.
Containment & transport protection: Packaging keeps food together, prevents spills, and protects products from shocks, pressure, and handling during transport.
Preservation barriers: Good materials block oxygen, moisture, light, and microbes, helping slow spoilage and extend shelf life.
Information, convenience & marketing: Labels provide safety info, nutrition data, and branding that guides shoppers and builds trust.
Sustainability & cost-efficiency: Modern packaging aims to reduce waste, use fewer resources, and support recycling without raising costs.
Common Food Packaging Materials & Their Characteristics
Food packaging comes in many forms, and each material has its own strengths and trade-offs. Understanding these helps you choose the right option for safety, shelf life, sustainability, and cost.
1. Plastics & Flexible Films
Plastics are the most widely used food packaging materials today. They include polyethylene (PE), polypropylene (PP), PET, and multilayer flexible films used for snacks, frozen foods, pouches, and more.
Pros
Lightweight & cost-effective — lowers shipping cost and material use
Highly versatile — can be molded, sealed, laminated, or shaped for many food types
Strong barrier options — multilayer films block oxygen, moisture, and odors well
Cons
Recycling challenges — multilayer films and mixed plastics are harder to recycle
Environmental concerns — growing pressure to reduce plastic waste
Some grades offer weaker heat resistance for hot-fill or microwave use
Plastics remain popular because they deliver strong performance at low cost, but sustainability concerns are pushing brands toward alternatives.
2. Metals: Aluminum, Tinplate, & Steel Cans
Metal packaging is widely used for canned goods, beverages, ready-to-eat meals, and long-shelf-life products.
Pros
Excellent durability — resists crushing, punctures, and heavy transport
Superior barrier protection — blocks oxygen, light, and moisture completely
Long shelf life — ideal for sterilized and preserved foods
Cons
Heavier than plastics — increases shipping costs
Higher material cost compared to paper and some plastics
Limited design flexibility aside from printing and labeling
Metal is one of the most reliable food packaging options—especially when safety, long-term storage, and protection are top priorities.
3. Glass Packaging
Glass jars and bottles are used for sauces, drinks, baby food, gourmet products, and premium items.
Pros
Chemically inert and non-reactive — keeps flavors pure with no leaching
Premium appearance — lets customers see the product clearly
100% recyclable without quality loss
Cons
Fragile and breakable, requiring careful handling
Heavy shipping weight — increases logistics cost
Not always suitable for on-the-go or high-volume SKUs
Glass is ideal when purity, flavor preservation, and premium branding matter most.
4. Paper, Paperboard & Molded Pulp
Paper-based packaging includes cartons, boxes, trays, molded fiber packaging, and wraps often used for bakery items, produce, takeaway, and dry foods.
Pros
Eco-friendly and renewable — aligns with sustainable packaging goals
Lightweight and printable — excellent for branding and labeling
Compostable or recyclable depending on coating type
Cons
Weaker barrier protection — often requires coatings or liners
Moisture-sensitive unless laminated or treated
May tear or deform under heavy loads
Paper-based materials continue to grow in popularity as brands push for greener packaging solutions.
5. Biocomposites & Biodegradable Materials
These include PLA, bagasse, bamboo fiber, starch blends, and other plant-based or compostable options.
Pros
Sustainable and biodegradable, reducing plastic dependency
Lower carbon footprint than petroleum-based plastics
Consumer-friendly branding — aligns with eco-conscious demand
Cons
Not always suitable for high heat (e.g., PLA softens at ~60°C)
Higher cost compared to standard plastics
Limited industrial composting access in some regions
Biocomposites are a strong choice for brands looking to improve sustainability while maintaining functional performance.
How to Choose the Right Packaging Material
Choosing the best packaging starts with understanding your product’s needs, market demands, and environmental impact.
Match material to product type: Liquids, frozen foods, acidic items, and dry goods all need different protection levels.
Check shelf-life & barrier needs: Look at moisture sensitivity, oxygen exposure, and temperature requirements.
Balance cost, performance & sustainability: Compare total lifecycle cost, recyclability, and durability.
Follow regulatory standards: Ensure materials meet food-contact safety rules and regional compliance.
Watch emerging trends: Multi-layer films, smart packaging, and circular-economy materials offer new ways to boost shelf life and reduce waste.

FAQs
What material is used for food packaging?
Food packaging materials include plastics, metals (like aluminum and steel), glass, paper/board, and biocomposites.
What are the 5 packaging materials?
Five standard materials are: plastics, metals, glass, paper/board, and biocomposites/biodegradables.
What are the 4 types of packaging?
Packaging types often refer to primary (direct contact), secondary (grouping), tertiary (bulk transport), and quaternary (distribution systems).
Is plastic #7 safe for food?
Plastic code #7 (“Other”) can include varied resins—some food safe, some not. It’s best used with caution because it may include bisphenol A (BPA) or other additives.
