Principles and characteristics of three-layer co-extrusion film blowing machine?

The three-layer co-extrusion blown film machine is a device that extrudes plastic blanks of different colors and properties through an extruder, extrudes them through the film head, and then stacks them together to form a composite film. The three-layer co-extrusion film blowing machine has the following characteristics:

1. Films with a three-layer structure can be produced. By controlling the feed ratio, the proportions of materials in different layers can be adjusted to achieve different performance requirements.

2. Each layer of material has different functional properties, such as moisture-proof layer, oxygen barrier layer and protective layer from the inside to the outside. The purpose is to ensure the quality and shelf life of the packaging.

3. It is efficient, stable and reliable, can produce a large number of high-quality films, and can quickly adapt to market demand.
