Air column bag raw material: PA+PE co-extruded film

Many customers who have used buffer air column bags have known that the buffer air column bag packaging can play a protective buffering role in the circulation process of product transportation, handling, storage, etc., and can replace traditional foam, pearl cotton, etc. in logistics and express delivery. The most ideal packaging material for buffer packaging. Many people have also seen the material introduction of the buffer air column bag and know that the air column bag is produced by PE+PA co-extruded film, which is not only environmentally friendly, but also has efficient buffer performance, but they do not know what kind of material the nylon co-extruded film is, and why is it environmentally friendly?

      Nylon co-extruded film is the use of different plastic materials with different barrier properties. Five/seven layers of co-extruded film can achieve high barrier effect on oxygen, water, carbon dioxide, odor, etc., so nylon co-extruded film has high barrier properties.

Because the main components of nylon co-extruded film are nylon + PE, its PE material is one of the common production materials for plastic packaging bags today. Adding nylon and other materials to it can make it more durable than ordinary plastic packaging. Composite strength, the higher the nylon content, the better the co-extrusion film toughness, but the material will also become hard, so in the production of nylon co-extrusion film, the general nylon content will be lower than the PE content, so five/seven layers The co-extruded film has the characteristics of stretching during processing, there is no delamination and peeling phenomenon, good flexibility, and excellent heat sealing performance.

Compared with glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, seven-layer and nine-layer co-extruded films have a greater cost advantage. Due to the simplicity of the process, the cost of the film product produced can be reduced by 10-20% compared to dry lamination films and other lamination films.

At the same time, the packaging produced by co-extruded film can adopt different structural designs, which can meet your different quality requirements.

Why is nylon co-extruded film an environmentally friendly and pollution-free packaging material? That is because its production raw materials are PE and nylon, and its PE is low-density polyethylene (LDPE). Residual solvent pollution problem, green and environmental protection.
