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

The majority of laminate films are made from plastic, but can also be made from paper, metal foil (usually aluminium) or fabric. In co-extruded films, all layers are extruded together at the same time, so there are no other non-plastic materials such as aluminium foil or paper.Coextruded films can b
