Wuhan modern plastic shackle film forming method
      Wuhan Modern Plastic Film has a variety of molding methods, mainly extrusion molding (including extrusion blown film, extrusion casting film method, extrusion composite film method), solution casting molding, calendering molding and secondary molding processing Dry composite membrane method, mechanical processing method, etc. www.handern.com Hollow board equipment
      1. Film extrusion
      Film extrusion is a film forming method that uses an extruder as the main forming equipment. It includes extrusion blown film method, extrusion cast film method, extrusion composite film method, etc. www.handern.com Hollow board equipment. Extrusion film blowing method is divided into flat blowing method, top blowing method, bottom blowing method, etc. according to the difference of bubble inflation and cooling method. The top blowing method is the most commonly used method for plastic film forming; the bottom blowing method is the simplest production method for high transparent plastic film. The extrusion blown film method can produce single-layer and multi-layer films. If the process of twice blowing the film bubble is adopted, the extrusion blown film method can produce biaxially stretched film and heat shrinkable film. The film produced by the extrusion film blowing method is cylindrical or sheet-shaped. Commonly used extrusion blown film production of plastic materials for films, LDPE, HDPE, L LDPE, PP, EVA, PVC, PA, BS, PVDC, etc. Extruded cast film method, also known as flat film method or "T" film method, is mainly used to produce single-layer or multi-layer sheet film. Extruded cast film is processed by subsequent stretching process, which can produce uniaxially stretched and bidirectionally stretched film, breathable impermeable film, and heat shrinkable film. Commonly used extrusion cast film method to produce film plastic materials, mainly LDPE, LLDPE, EVA, PP, PET, PA, etc. www.handern.com
      The extruded composite film method is to apply the extruded hot-melt film directly to the sheet, film material, such as paper, fabric and plastic film, which are continuously conveyed, and then composite the film by cooling and pressing. Extruded composite film does not use solvents, and its extruded hot melt and substrate can be two different materials. The compound materials produced by the extrusion compound method mainly include PE, PA, PET, EVA, EVOH, EAA, high polymer, etc. www.handern.com Hollow board equipment
