BX650 Woven Bag Inner-Film Laminating Machine

This line can efficiently make the inner surface of tubular woven cloth laminating with the outer surface of tubular iner lining filmstablely by a heating bonding device. The tubular inner lining film is double-layer & co-extrusion blowing film which is 0.03mm to 0.04mm thick. The inner layer of tubular inner lining film is made from Low-Density Polyethylene(LDPE), the outer layer of it(the layer which is bonded to the woven cloth) is made from Ethylene Vinyl Acetate Copolymer(EVA).The woven cloth is mainly made frompolypropylene(PP).

The melting temperature of EVA is lower than the melting temperature of LDPE and PP,and the melting EVA layer can be bonded to the no melting PP woven cloth. We can take advantage of this features to bond and laminate the tubular inner lining film and tubular woven cloth together at appropriate temperature by series of procedures.

The inner lining film can be laminated with the woven bag in a lower temperature,so the bags produced by this line have fantastic characteristics. They are flexible,strong,durable,and have low breakage rate. In the bonding process, the bags are flttened by heating,so the bags are smooth and beautiful. The advantages of common woven bag with separated inner lining film and the advantages of laminating bag all appear in bags produced by this machine. These bags are advanced packing product and they can be used widely in multiple areas.

The cost and price of the bag produced by this line are slightly higher than the same type and same weight common woven bag with separate inner lining film, but its performance is better, its standard is higher. Compared with the common lining film woven bag, these bags can avoid the phenomenon that the inner lining film drop from the woven cloth by crash from putting goods into it. This bag can be produced continually,efficiently,quickly in the production line. It's labor-saving and can be produced with large-scale. In contrast,inserting lining film to tubular woven cloth by handwork or turning outer layer to inner layer by handwork both are disconnected and inefficient. Bags produced by this machine is widely used for packaging of industries such as chemical materials,fertilizer,feed and food,etc.
