Co-base barrier laminate films are barrier films produced by a co-extrusion lamination process. The co-extrusion lamination process is a molding method in which two or more different plastics are molten and plasticized by two or more extruders, respectively, into a pair of dies, and the paper cups a

Analysis of the causes of large noise in the work of plastic sheeting machines:(1) Motor parts1、Serious wear of rolling bearing for rotor shaft or low precision of bearing.2、The rotor shaft is bent and deformed.3, Carbon brush installation work position is incorrect.4、The rotor shaft end wind blade

1. Static electricity in plastic filmsWhen insulating materials are rubbed together, static electricity is easily generated; the higher the insulation of the object, the easier it is to generate static electricity. Plastic products usually belong to highly insulating substances, especially packaging

Hot melt adhesives are a mixture of basic polymers, tackifying resins (tackifiers), waxes and antioxidants. In order to improve their adhesion, fluidity, heat resistance, cold resistance and toughness, a certain amount of plasticizers, fillers and other low molecular polymers can also be added as ap

PP (polypropylene), polypropylene, is a light thermoplastic synthetic resin with excellent performance, with chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good abrasion resistance processing properties. However, most of what we see on the market
