With the rapid development of the plastics industry, plastics machinery has also evolved significantly, and at the same time, there are various plastic film preparation processes followed by continuou...

1. Shrinkage phenomenon The viscoelastic behaviour of the polymer melt when the film is calendered with a T-die head causes (i) problems such as the shrinkage phenomenon, where the width of the ...

Extrusion cast laminators, which some manufacturers and users in the industry are used to calling film laminators, are also called extrusion laminators, cast machines, extrusion cast machines, cast la...

Plastic film, especially BOPP and other biaxially oriented film, there is an obvious molecular orientation, in a state of stress concentration, when there is no cut, it is difficult to tear, but once ...

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...
