Wuhan Handern 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 blown film method is divided into flat blow method, up blow method, down blow method, etc. according to the difference of bubble inflation and cooling method. The upper blowing method is the most commonly used method for plastic film forming; the lower blowing method is the simplest production method for highly transparent plastic films. The extrusion blown film method can produce single-layer and multi-layer films. If the process of twice inflating the film bubble is adopted, the extrusion film blowing method can produce biaxially stretched film and heat shrinkable film. The film produced by the extrusion blown film method is cylindrical or sheet film. Commonly used extrusion blown film method to produce film plastic materials, including LDPE, HDPE, L LDPE, PP, EVA, PVC, PA, BS, PVDC, etc. Extruded cast film method, also known as flat film method or "T" shaped film method, is mainly used to produce single-layer or multi-layer sheet film. Extruded cast film is processed by the subsequent stretching process to produce unidirectional and biaxially oriented films, breathable impermeable films, and heat-shrinkable films. It is the fastest-growing film forming technology in recent years. Commonly used extrusion cast film method to produce film plastic materials, mainly LDPE, LLDPE, EVA, PP, PET, PA, etc. www.handern.com Hollow board equipment
      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 pressurizing. The 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
