Why is laminated film critical to food packaging?
Laminated film packaging is versatile and durable for food packaging. Its one-layered structure blocks air, oxygen, and light, preserves product freshness and flavor, withstands humidity and extreme temperatures, and extends shelf life. Customized printing visual characteristics can boost a company’s packaging brand, making laminated film popular in food packaging.
Additionally, biodegradable laminating films are the future of food packaging. Cutting-edge technology and eco-friendly techniques make these materials durable, protective, and environmentally beneficial.
Laminated films preserve product quality and shelf life.
Laminated films prevent food from spoiling. It works in three ways:
Moisture/oxygen/light barrier
Moisture resistance: Norberus uses EVA-coated laminates to prevent mold in baked goods and snacks. Polypropylene films can reduce water vapor transfer by 90%, prolonging shelf life by 30-50%.
Oxygen barrier: Aluminum foil laminates delay meat and dairy oxidation. According to the Food Packaging Forum, oxygen barrier films can improve fresh fruit shelf life by 2-4 weeks.
UV protection: Transparent films with UV blockers maintain the color and nutrients of coffee and juice.
Composite films limit moisture, oxygen, and light, preventing food spoilage, oxidation, and nutritional loss. Light, moisture, and oxygen barrier qualities of aluminum laminated films extend food shelf life, making them essential in the food business.
Laminated films preserve flavor and freshness.
Laminated films preserve flavor and texture. Example:
Laminate-lined coffee bags retain their aroma for 12 months, compared to 3-6 months for unlined bags.
Cheese packaged on PVDC-coated film had a 60% lower rancidity rate after 60 days than unlaminated cheese.
Prevent contamination and harm.
Puncture resistance: Nylon-reinforced films safeguard fragile foods during shipping. Data shows they reduce chip and cereal breakage by 40-60%.
Tamper-resistant: Sealing visible films protects products. A 2023 survey found that 72% of consumers shun tampered packaging.
According to Packaging Digest, laminate packaging extends perishable food shelf life by 2-5 times.
Laminated films prevent food contamination and damage during shipping. They include multiple layers for strength and puncture resistance, keeping food intact. The film’s thicker structure avoids ripping and damaging products with sharp edges or corners.
Sustainable laminates’ future
Biodegradable laminates revolutionize the industry:
PLA films: Made from corn starch, these break down in 6-12 months, compared to hundreds of years for typical polymers.
Water-soluble films: Polysack uses PVOH coatings to make compostable packaging that breaks down in 24 hours under industrial composting conditions.
Laminate films improve brand image and appearance.
Laminating films benefit food packaging by protecting it, extending shelf life, and improving appearance. They keep products fresh by resisting moisture and oxygen. They also support personalized designs that attract consumers and distinguish brands on shelves.
Customizable colors/graphics/textures
Laminates can be personalized with colors, images, and textures. This customization lets firms build eye-catching packaging that complements their image.
Bold, distinctive designs: Laminate films let you print brilliant colors, complicated patterns, and metallic or imitation leather textures.
Our pouch manufacturing services include customizable printing with up to ten colors, UV, matte, tactile film, and other processes.
Anti-scratch/anti-fouling
Laminating films with anti-scratch and anti-fouling properties keep packaging looking professional. These coatings prevent fingerprints and smudges and keep the packaging looking good. Electronics and luxury products are packaged with laminating films.

Composite Film for Food Packaging
Materials and technological innovations
Laminating films for food packaging incorporate advanced materials and processes that combine functionality, sustainability, and high quality. They utilize multilayer composites, sustainable alternatives, and advanced lamination processes to meet industry needs.
Multilayer composites (PE/PET/aluminum foil)
Multilayer composites in laminating films typically comprise polyethylene (PE), polyethylene terephthalate (PET), and aluminum foil. Each material has unique properties:
Polyethylene (PE): Flexible and moisture resistant.
Polyethylene terephthalate (PET) provides strength, transparency, and gas barrier properties.
Aluminum foil provides an effective barrier to light, oxygen, and moisture.
These materials are combined to create composite films with superior barrier properties, mechanical strength, and flexibility. For example, a typical construction might include a layer of PET (for stability), a layer of aluminum foil (for barrier protection), and a layer of PE (for flexibility and sealing).
For example, the three-layer polyethylene/aluminum foil/polyethylene film used in coffee bags can keep out oxygen for up to 12 months while ensuring breathability for the coffee beans.
Films that can come into direct contact with products (especially food and pharmaceuticals), PE films, CPP films, and VMCPP films can be put directly into the innermost layer to contact food. They are safe but require the raw material film to be food-grade.
Sustainable alternatives (biodegradable films)
The food packaging industry increasingly adopts sustainable options, such as biodegradable films, to minimize environmental impact. Biodegradable films are made from polylactic acid (PLA) derived from renewable resources such as corn starch. These films can break down naturally, reducing plastic waste.
Polylactic acid (PLA): a biodegradable polymer derived from renewable resources. It has good barrier properties and is compostable.
Paper Matrix Composites: combines paper with biodegradable polymers to create a sustainable packaging solution.
Environmentally Friendly Ingredients:
PBAT (polybutylene terephthalate adipate) breaks down into harmless compounds in compost.
PHA (Polyhydroxyalkanoate): naturally produced by bacteria and fully biodegradable.
rPET (recycled PET): repurposes plastic bottles into durable packaging.
According to Grand View Research, the global biodegradable packaging market was $1.1 billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 6.6% from 2021 to 2028.
Advanced Lamination Processes
Advanced lamination processes are critical to producing high-quality laminating films. Standard lamination methods include hot melt lamination and solvent-free lamination:
Hot-melt lamination: Heat melts the adhesive between two film layers. This method is fast and provides a strong bond.
Solvent-free lamination: This method uses an adhesive that reacts and cures without solvents. It is more environmentally friendly and is becoming increasingly popular due to its low environmental impact.
These processes ensure that the layers of the laminating film are firmly bonded, providing excellent barrier properties and durability. The choice of lamination process depends on the specific requirements of the packaging application, such as the type of product being packaged and the desired shelf life.
