PP.HIPS.PE.EVA.EVAOH Single Layer Multi-Layers Composite Sheet Production Line
PP, HIPS, PET, EVA, EVAOH Composite Sheet produced by JINHU PP, HIPS, PET, EVA, EVAOH Composite Sheet Production line has characteristics such as high intensity, good temperature resistance, enhanced rigidity, flame retardant, improving toughness and good anti-corrosion performance. JINHU multi-layers composite sheet production line is capable of continuously producing mono-layer or multi-layer PP/HIPS/PET/EVA/EVAOH sheet with thickness of 0.2mm to 2mm and width of 600mm to 1800mm.
PP, HIPS, PET, EVA, EVAOH Composite Sheet is suitable for product packaging, food packaging, stationery, printing, gifts and handicrafts manufacturing in various industries.
In sheet production line, raw materials are fed into barrel of the extruder through hopper. Resins comes into contact with screw through the feed throat which is an opening near the rear of the barrel of extruder. After that, rotating screw forces the resin forward into the heated barrel. The molten plastic exit from front of the barrel and enters the die through screen pack/breaker plate. The screen pack and breaker plate create back pressure in the barrel which is required for uniform melting and proper mixing of the polymer. When molten plastic enters into the die, the die gives the final shape. Then product cooling process is achieved by pulling the extrudate through a set of cooling rolls. In sheet production line, these cooling rolls provides necessary cooling as well as determine sheet thickness and surface texture.
HIPS sheet has improved physical properties, high strength, low weight ratio (the length of PVC is 34% less than the HIPS sheet with same specifications and weight) and high efficiency.
