For the semi-rigid sheet structures and flexible film structures discussed so far, the resins used are both different and partly identical. Semi-rigid sheets mostly use high modulus resins such as HIP...

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 molt...

Analysis of the causes of large noise in the work of plastic sheeting machines: (1) Motor parts 1、Serious wear of rolling bearing for rotor shaft or low precision of bearing. 2、The rotor shaf...

1. Static electricity in plastic films When insulating materials are rubbed together, static electricity is easily generated; the higher the insulation of the object, the easier it is to generate s...

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...

PP (polypropylene), polypropylene, is a light thermoplastic synthetic resin with excellent performance, with chemical resistance, heat resistance, electrical insulation, high strength mechanical prope...

I. Factors affecting the performance of vapour plated silicon oxide barrier packaging films Vapour plating base film, vapour plating method, vapour plating conditions as well as the composition o...

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...
