Polyamide (PA) films are one of the key types of barrier films, frequently used in the food industry and many other sectors. Thanks to their strong performance, especially in vacuum packaging applications, they offer effective solutions for both manufacturers and consumers.

In the packaging industry, PA films are produced using either cast or blown extrusion technologies. Due to their high barrier functionality, they are commonly used in structures such as PAPE, PEPAPE, or BOPA.

🔧 Key Properties of PA Films

• Lower elastic modulus compared to PET films

• Strong barrier against moisture, odors, and oxygen

• Good thermal resistance

• High radiation resistance

• Moderate chemical resistance – not extremely strong, but effective against many chemicals

📦 Common Applications of PA Films

• Packaging of meat, fish, and other products requiring strong barrier properties

• Medical packaging and sterile environments

• Sterilization and retort processes

• Hot-melt adhesive packaging applications

• Vacuum packaging for food and non-food products
