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 of ...

All films made from thermoplastics share a common problem: special production techniques must be used to achieve a uniform thickness. Unlike extruded tubes and sheets, extruded films can have large va...

Nanjing Sumino Seiko co-extruded barrier composite films are usually made from a combination of barrier plastics, polyolefin plastics (moisture-proof plastics, generally also used as heat sealing laye...

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...
