How PET film optimizes product quality1. Bow phenomenonAt the entrance of the stenter machine, the transverse traction film is in a straight line, while at the exit of the capping machine, the film star and the same curved shape. Bow phenomena cause differences in lateral properties. The expansion o

Co-extrusion tubular film co-extrusion flat film filmThe co-based barrier composite film refers to the barrier film produced by the co-extrusion composite process. The co-extrusion composite process is to put two or more different plastics through two or more extruders, respectively melt and plastic

Characteristics of co-extrusion filmIn the processing of the film, one raw material is extruded onto another film that has been made or different types of films have been made, and the adhesive is used to bond each other to form a multi-layer film. This product called a composite membrane. Co-extrus

Sheet machine extrusion The plastic sheet produced by the extrusion method has good mechanical properties and optical properties, and has the characteristics of light volume, good light transmission, heat preservation, sound insulation, and convenient installation. It can be used as structural mater

Anti-rust film production process Antirust film is the abbreviation of VCI antirust film (VCI antirust film), which is a new generation of innovative high-tech products based on the combination of polymer materials and VCI vapor phase antirust technology development. After the antirust metal article
