1、 Shrinkage phenomenonThe viscoelastic behavior of the polymer melt when the film is cast with a T-shaped die causes the following problems① The width of the film narrows due to the shrinkage phenomenon;(ii) The problem of film stretching, which is the phenomenon of material surge or breakage durin

Sumino Seiko Cast Film Production LineCompared with extruded blown film, extruded cast film has the advantages of good film transparency and thickness uniformity. Cast film resins are mainly polypropylene, polyethylene, and polyamide.In order to manufacture extrusion cast film, in the extruder, the

Antirust film is the abbreviation of VCI antirust film, which is a new generation of innovative high-tech products based on the combination of polymer materials and VCI gas phase antirust technology development. After the rust-proof metal articles are packed and sealed with antirust film (which can

Co-extruded barrier multilayer laminated films are usually made of polyolefin resins, with polyethylene, polypropylene and other plastics being the most widely used. In addition to the moisture-proof function, they often also play the role of heat sealing layer and carrier layer.1. PolyethylenePolye
