Raw materials of air column bag: Nylon Co-Extruded Film

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

Let's analyze the production raw materials of air column bag .

Nylon co-extruded film is the use of different plastic materials with different barrier functions. 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 function.

Nylon co-extruded film is mainly composed of two kinds of materials: nylon + PE. Its PE material is one of the most common production materials for plastic packaging bags. Adding nylon and other materials in between can make it have the ability to surpass ordinary plastic packaging. Composite strength, the higher the nylon content, the better the co-extrusion film resistance, but the material will also become hard, so in the production of nylon co-extruded film, the nylon content is generally 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 function.

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

At the same time, the packaging produced by the co-extrusion film can choose different structural designs to meet your different quality requirements.

Why is nylon co-extruded film environmentally friendly and does not pollute the packaging material? That is because its production materials are PE and nylon, and its PE is low density polyethylene (LDPE). The product is non-toxic, tasteless, odorless, and milky white particles, so no Residual solvent pollution problem, green and environmental protection.
