PA/PE food packaging film

PA has good oxygen barrier properties, which helps to prevent the oxidation of the packaged products. This is particularly important for food products, as oxygen can cause spoilage, rancidity, and the growth of aerobic microorganisms.

Information

Structure

PA/PE packaging film typically features a multi - layer structure. The PA layer, commonly known as nylon, offers high mechanical strength, excellent puncture resistance, and good gas barrier properties. The PE layer, on the other hand, provides flexibility, heat - sealability, and moisture resistance. The combination of these two materials in a co - extruded or laminated structure results in a film with enhanced overall performance. For example, in a typical co - extruded PA/PE film, the PA layer may be on the outer side to protect against punctures during handling, while the PE layer is on the inner side for heat - sealing and moisture protection.

Barrier Properties

Oxygen Barrier: PA has good oxygen barrier properties, which helps to prevent the oxidation of the packaged products. This is particularly important for food products, as oxygen can cause spoilage, rancidity, and the growth of aerobic microorganisms. By reducing oxygen permeation, PA/PE films can extend the shelf - life of food items such as cured meats, cheeses, and baked goods.

Moisture Barrier: PE is known for its low water vapor permeability. In the PA/PE film, the PE layer acts as an effective moisture barrier, protecting products from moisture - induced damage. This is essential for products that are sensitive to humidity, such as electronics, pharmaceuticals, and some types of food like dried fruits and grains.
