2.Detailed description of PVDF solar plate back film production line

PVC

PVC transparent sheet have many advantages of fire-resistance, high quality, low cost , high transparent, good surface, no spot, less water wave, high strike resistance, easy to mould and etc. it applys to different kinds of packing, vacuuming and case, such as tools, toys, electrics, food, medicine and clothes.

PVC Transparent Soft Sheet Extrusion Line

PVC transparent soft sheet is product instead of the traditional door curtain. It is soft, clear, insulation, safe, environmental protection, acid resistance, no peculiar smell, easy to clean, and etc, also can be used in cold and heat insulation, save energy, wind proof, sound proof, table pad, daylighting, industrial damping, safety warning, protect surface, these application used in refrigeration, foodstuff, printing, weaving, electrics, instrument, medicine, storage. It has good effect on insulation for electricity, and harmful light.

pp/ps sheet extrusion production line is common for single-extruder single-layer sheet production line and double-extruder co-extrusion three-layer sheet production line. There are also multi-extruder co-extrusion multi-layer production line, which can process 7-9 layers of composite sheet at most, such as high-barrier evoh multi-layer co-extrusion production line. This type of extrusion line can process pp, ps, pe and other polyolefin materials.

gwell pp/ps sheet production line:

multi-extruder co-extrusion technology is adopted to produce multi-layer co-extrusion composite pp and ps sheet, such as aba, abcba, abcdcba and other multi-layer structure, which is widely used in heat forming, printing, hardware packaging, electronic tray, flocking, food, clothing, tools, toys, stationery pieces, decorative pieces and so on.

* equipped with precise distributor, evenly layered, adjustable proportion of each layer, digital precise control.

Gwell highly transparent PVC soft curtain production line adopts single screw extruder with PVC granules. The unique screw structure, combined with the Gwell vacuum hopper, enables the product to achieve highly transparent effect, and the product will not harden in the cold temperature of 30 degrees below zero. Auxiliary design adhering to the principle of multi-purpose machine, in the case of no need to make any changes to the equipment, can produce three different patterns of PVC curtain without shutting down the machine.
