What kind of material is processed in the textured vacuum packaging bag, which is compressed by several layers of material composite?

Textured vacuum packaging bags are processed by seven-layer co-extruded film, seven-layer co-extruded film is made of environmentally friendly materials using physical hot melt method of a multi-layer co-extruded without the need for multi-layer laminating, is a purely green packaging materials, suitable for a variety of food packaging.

Seven-layer co-extruded film co-extrusion technology directly using more than three kinds of plastic particles as raw materials, seven-layer co-extruded film more than five-layer symmetric structure of ABCBA and seven-layer, such as PA or EVOH for the barrier layer, PE for the heat sealing layer, through several sets of the extruder respectively so that each kind of plastic melting and plastics, for a pair of mouth mould, and then after further processing, the production of multi-layer composite film.

Seven-layer co-extruded film co-extrusion technology is different from dry composite and other composite technologies, it does not need to first make the plastic particles into a film-like intermediate products, multi-layer co-extrusion technology represents the direction of economic and environmental protection. It is a high quality food packaging material.
