PA PE film 0414

 

Polyamide (PA)
- Material Properties:
- Barrier Properties: PA (commonly known as Nylon) provides excellent barrier properties against oxygen, aromas, and other gases.
- Strength and Durability: It is strong and durable, offering good puncture resistance and mechanical strength.
- Temperature Resistance: PA can withstand high temperatures, making it suitable for hot-fill and retort applications.

Polyethylene (PE)
- Material Properties:
- Sealability: PE is known for its excellent sealing properties, allowing for easy and secure closure of packaging.
- Flexibility: It is highly flexible and can conform to various shapes and sizes.
- Moisture Barrier: PE provides a good barrier against moisture, ensuring that the contents remain dry and protected.
- Cost-Effective: PE is generally more cost-effective compared to other plastic materials.

PA/PE Film Characteristics
- Combination Benefits:
- Multi-Layer Structure: PA/PE films are typically multi-layered, with each layer contributing specific properties. The PA layer provides the necessary barrier properties, while the PE layer ensures good sealability and flexibility.
- Mechanical Strength: The combination of PA and PE results in a film that is both strong and flexible, making it ideal for packaging applications that require durability and ease of handling.
- Barrier Protection: The PA layer offers excellent protection against oxygen and other gases, which is crucial for preserving the quality and shelf life of water and beer.
- Chemical Resistance: PA/PE films are resistant to a wide range of chemicals, including those commonly found in beverages, ensuring that the packaging does not react with or alter the product inside.
