About multi-layer co-extrusion
Our commonly used meat bags, poultry bags, seafood bags, cheese bags, etc. are basically composite films made of multi-layer films, and then these composite films are used to make packaging bags with different functions.
Multi-layer co-extrusion technology directly uses three or more plastic particles (or plastic powder) as raw materials, and each plastic is melted and plasticized by several extruders, and then fed into a pair of die (or through a distributor , the plastics supplied by each extruder are combined and then supplied to the die), and then further processed to produce a multi-layer composite film. Tipack can even achieve 11-layer co-extrusion at present, so as to meet more functional needs.
It has the advantages of concentrating the advantages of a variety of materials, effectively controlling the cost, realizing the adjustment of the film structure according to the needs, and having a wide range of use. Sealing performance, and there is no need for additional compounding during processing, and it does not involve problems such as printing ink, adhesives and auxiliaries. Therefore, it is a relatively green and cost-effective production technology process, whic
