About multi - layer co-extrusion film blowing machine related introduction

In order to meet the needs of some special functions of plastic film packaging materials in the production process, a variety of characteristic materials (such as air permeability, waterproof, heat preservation, toughness, etc.) are blown film and co-extruded together to form a multi-functional plastic film, and a multi-layer co-extruded film blowing machine is developed. The purpose of multi-layer co-extrusion film blowing machine is to play the advantages of a variety of materials, to avoid some shortcomings of single material or single layer film blowing machine.

For example, PP and PE co-extrusion film blowing machine, it is the combination of the characteristics of PP material hardness and high brightness of PE material, the production of two characteristics of the combination of film
