When plastic film is extruded and moulded, the film blank extruded from the moulding die is generally stretched in order to increase the strength and improve the transparency of the finished product. In practice, also film extrusion stretch moulding refers to the stretch moulding of film sheets form

Plastic film refers to polymer synthetic materials as the main raw material, and other auxiliary materials in a certain proportion of uniform mixing, in the plastic moulding machinery and equipment for a certain thickness (thickness of 0.01 ~ 0.25mm), the width and unlimited length of the surface of

First, solvent-free composite process status and its developmentAfter the 1980s, solvent-free laminating process in foreign industrial developed countries is growing rapidly, the application of dry laminating is significantly reduced (especially in Europe, after the 1980s, the new solvent-free lamin

Flat film method step by step bi-directional stretching process as follows: raw materials → extrusion → casting → longitudinal stretching → cutting edge → corona treatment → winding → large film rolls → aging → slitting → finished product.Thick film for stretching should be amorphous, process to ach
