Food Packaging Materials Explained: Types, Uses, and Key Differences

Paper, plastic, PLA, kraft—on the surface, food packaging materials look similar. But in real-world use, choosing the wrong option often leads to leaking containers, soggy food, failed deliveries, or products that don’t survive transport.

Many food brands source their food packaging supplies based on habit, price, or appearance, only to discover later that the material does not perform under real conditions.

Why does one package work perfectly for a hot meal, while another fails during delivery?

Why does “eco-friendly” packaging sometimes cost more but still cause customer complaints?

The truth is that food packaging materials behave very differently under heat, cold, moisture, and pressure. Without understanding these differences, packaging decisions become guesswork instead of strategy.

1. Classification of Food Packaging Materials

Food packaging materials can be broadly categorized based on their raw materials, performance properties, and environmental impact.

1.1 Paper-Based Food Packaging Materials

Paper-based materials are widely used in paper cup packaging, including paper coffee cups and disposable paper cups for food & beverage, especially for hot drinks, cold beverages, and single-serve applications. They come from wood fibers and include cardboard, kraft board, and coated papers. These materials are lightweight and offer excellent printability, making them ideal for boxes used in dry foods like cereals, cookies, and baked goods. Paper packaging allows breathability, which helps prevent moisture buildup in certain products. However, without treatment, it absorbs liquids easily, so coatings are often added for better water resistance. In recent years, the use of recycled paper has increased significantly, helping conserve resources and appeal to eco-conscious consumers.

1.2 Kraft Paper Food Packaging

Kraft paper is produced using the sulfate process, which preserves long fibers and gives the material superior strength and tear resistance. It typically features a natural brown appearance that conveys an eco-friendly, minimalist aesthetic.
Kraft paper is widely used for paper food boxes, takeaway food containers, anddisposable food packaging boxes in the foodservice industry. Its strength and tear resistance make it suitable for both dine-in and takeaway applications.
When coated, kraft paper provides effective grease resistance, making it ideal for oily foods such as fried chicken, burgers, and pastries. It is biodegradable and recyclable, making it a preferred choice for brands focused on sustainability.

1.3 Plastic Food Packaging Materials (PE and Related Types)

Polyethylene (PE) is one of the most common plastics in food packaging, including low-density PE (LDPE) and high-density PE (HDPE). PE films are flexible and resistant to low temperatures, commonly used for freezer bags, cling wraps, and bottles. They provide excellent barriers against moisture and oxygen, keeping food fresh longer at a low cost. PE is suitable for fresh produce, meats, and frozen products. Multi-layer PE composites further enhance preservation capabilities.

 1.4 Biodegradable Food Packaging Materials (PLA and Alternatives)

Polylactic acid (PLA) is derived from renewable resources like corn starch, making it a leading biodegradable plastic alternative. It offers high transparency similar to traditional plastics and is used for cups, trays, and films. PLA can break down in industrial composting facilities, reducing long-term environmental impact. Other alternatives include PHA (polyhydroxyalkanoates) and starch-based materials, ideal for short-shelf-life foods.

1.5 Other Common Food Packaging Materials

In addition to the main categories, other materials are used for specific applications:

• Aluminum foil provides excellent barrier properties for long-shelf-life and sterilized foods.
• Glass packaging offers premium protection, chemical stability, and high-end appeal.
• Composite materials combine paper, plastic, and aluminum layers for vacuum packaging, aseptic cartons, and cans.

2. Food Safety and Protection from Packaging Materials

One of the primary functions of food packaging is to protect food from external factors that can affect quality and safety.

2.1 Barrier Against Air, Moisture, and Grease

Food packaging materials must create effective barriers to protect contents from external elements like oxygen, water vapor, and grease. Oxygen exposure can cause oxidation, leading to rancidity in fats and loss of flavor in many products. Moisture barriers prevent sogginess in dry goods or drying out in moist items, while grease resistance is crucial for fried or oily foods.

Polyethylene (PE) excels here with its strong moisture and oxygen barrier properties, making it ideal for fresh produce and frozen items. Paper-based materials often require coatings, such as wax or polymer layers, to achieve similar protection without becoming soggy. Kraft paper, when coated, offers good grease resistance for takeout foods. PLA provides moderate barriers but performs well in short-shelf-life applications. Multi-layer composites combine these strengths for optimal protection. Overall, the choice of barrier depends on the food type and required shelf life.

2.2 Preventing Contamination During Storage and Transport

Packaging plays a key role in shielding food from physical damage, dust, insects, and microbial contamination throughout the supply chain. Strong materials like kraft paper resist tears and punctures during handling and shipping. Sealed PE bags block external contaminants effectively, especially in vacuum or modified atmosphere packaging (MAP) that removes oxygen to inhibit bacterial growth. Paper packaging allows some breathability, which benefits fresh produce by preventing mold, but needs careful sealing. Coatings on kraft or paper enhance durability against impacts. Transportation stresses, such as stacking or temperature fluctuations, require robust designs to maintain integrity. Proper sealing techniques, like heat sealing for plastics, ensure no entry points for pollutants. In global supply chains, compliant packaging reduces risks of recalls due to contamination.

2.3 Food-Grade Standards and Compliance

Food packaging materials must meet stringent regulatory standards to prevent the migration of hazardous substances.

• United States: FDA 21 CFR regulations require food contact materials to be safe and compliant.
• European Union: (EC) No 1935/2004 and (EU) No 10/2011 regulations regulate food contact plastics and are scheduled for update in 2025, further tightening chemical restrictions.
• China: The GB 4806 series of standards regulate food contact materials.

PFAS and other hazardous substances are subject to increasingly stringent restrictions globally. Manufacturers must provide a Declaration of Compliance (DoC) and conduct migration testing to ensure product safety.

3. Sustainability and Environmental Impact of Food Packaging Materials

 3.1 Recyclable and Compostable Packaging Materials

Recyclability and compostability are central to sustainable packaging. Paper and kraft paper are highly recyclable, with established global recycling streams reaching over 80% in some regions. PLA is industrially compostable, breaking down in facilities but not always in home setups. Bagasse from sugarcane is both recyclable and compostable. Mono-material designs, like pure PE, improve recycling rates over composites. Certifications like EN 13432 for compostability guide proper disposal. Many brands shift to these to meet circular economy goals. Challenges include contamination in recycling streams from food residues.

3.2 Reducing Plastic Waste in Food Packaging

Traditional plastics contribute significantly to global waste, prompting reductions through alternatives and regulations. The EU’s PPWR in 2025 mandates recyclability and reuse targets, cutting single-use plastics. Brands adopt bio-based options to lower fossil fuel dependency. Extended Producer Responsibility (EPR) laws in multiple countries make companies accountable for end-of-life management. Innovations like thinner films reduce material use while maintaining performance. Consumer pressure drives reusable systems in foodservice.

3.3 Environmental Impact Comparison by Material Type

Life-cycle assessments compare impacts across materials. Paper and kraft have lower carbon footprints but higher water usage in production. PE relies on fossil fuels, leading to persistent pollution and higher greenhouse gases. PLA from renewable sources reduces emissions but requires industrial composting for full benefits. Studies show biodegradables like PLA-coated kraft can have lower overall impacts when properly disposed. Recycled content further lowers footprints for all types.

3.4 Trends Toward Greener Food Packaging Solutions

In 2025, trends include mono-materials for easier recycling, algae-based plastics, and smart coatings for better barriers.
