PLA PBS PBAT Starch Straw Sheet Extrusion Line is suitable for PLA (PLA) and modified PLA. The whole machine is controlled by PLC, and functions such as actual parameter setting, data operation, feedback, and alarm are automated. Using multi-extruder co-extrusion technology, multi-layer co-extrusion composite PLA or starch sheets can be produced. Widely used in thermoforming, printing, metal packaging, etc
Plastic Extruder manufacturer, PVC Rigid Sheet Extrusion Line adopts conical twin-screw extruder according to the characteristics of transparent PVC material, combined with the GWELL hopper, screen changer, melt pump enables the product to achieve highly transparent product, and the product will not turn to be hardened in the cold temperature of 30 degrees below zero.
single-layer or multi-layer sheet extrusion machine Its one of the most advanced production lines with matured technology and stability in Compared with other same kind equipment, it s over 30% higher in overall efficiency. This line is suitable for PS, PP, PE as well. PETG sheet PETG is called low temperature PET, it s a new environment-friendly packing material with features such as high luster, good transparency, excellent barrier property, self-adhesion, which is used for glue bonding and high-frequency processing. CPET sheet CPET is a kind of modified PET, with good resistance to high temperature, It is usually used for package in microwave oven. PET stereoscopic optical grating sheet It can be used as top grade package for cosmetics, common goods such as stationery, advertisements, posters and all kinds of cards. PLA sheet PLA is a kind of line shape Aliphatic Polyesters. PLA can be used in rigid package of fruits, vegetables, eggs, cooked food and roast food, also can be usedfor packaging of sandwich, biscuit and some other packages like fresh flower.
Features of Dwell s EPE(EVA/POE/EVA) solar film extrusion line:
Film Layers structure: According to the finished film, EVA/POE/EVA film has three layers(EPE film). It will be based on the customer requirements, EPE solar film extrusion line can also produce EVA or POE single layer.
China EVA / POE / EPE solar film is used for solar cell encapsulation. After lamination and curing, it is bonded and sealed. It plays the role of high light transmittance, preventing water vapor penetration, high and low-temperature resistance, and ultraviolet light resistance to ensure the stable and efficient use of battery modules. It is a durable and reliable packaging material. The EVA / POE / EPE packaging film extrusion line of Dwell machinery is in a leading position in the world.
Advantages of the Dwell EPE(EVA/POE/EVA) solar film extrusion line
If producing EPE film, the line speed of the EPE solar film extrusion line can reach 12m/min-15m/min, if EVA, can reach15-18m/min, and if POE, can reach 10-13m/min.
Cooling parts to ensure shrinkage rate is less than 3%.
DWELL special winder to ensure micro-tension, and achieve automatic winding and cutting.
Comparison of the Dwell EPE(EVA/POE/EVA) solar film and EVA solar film and POE solar film
1.Transparent EVA solar film: with high light transmittance, it is used for bonding glass and cells; The raw materials are EVA resin and various modifiers, which are cheaper.
2.White EVA solar film: compared with transparent EVA solar film, the pretreatment of white fillers such as titanium dioxide is added. It has a strong barrier, low light transmittance, and high reflectivity, which can improve the power generation of components. It has strong resistance to damp-heat aging and ultraviolet aging and can inhibit the aging and cracking of the back sheet.
3.Poe solar film: Poe solar film has a higher water vapor barrier rate and stronger anti-PID performance so the module can be used for a long time. It is the main packaging adhesive film of a double-sided double glass module and film module at present. 4.EPE(EVA/POE/EVA)solar film: It has both the anti-PID performance of POE and lamination efficiency of EVA solar film and reduces the use of POE particles to achieve cost reduction and efficiency increase. At present, it is mainly used in high-efficiency components.
