    Composite plastic woven bag is a plastic woven bag (short cloth) as the base material, after the flow of the composite made of (cloth/film composite for two, cloth/film/paper compound for the triple). They are mainly used in the packaging of fertilizers, synthetic materials, explosives, grain, salt, minerals and other powdered or granular solid materials and flexible items.Plastic Bag Making Machine

    Bag processing is the final process of plastic soft packaging production and processing, if the bag quality is not qualified or consumption is too high, then light is equal to the previous process of naught, heavy to the tourists to the claim for the enterprise's production and operation of a major impact. Bag Machine Hot seal does not completely cause the contents of leakage or deterioration how to do? Reason: The film's anti-pollution heat sealing is bad, mainly is the resin used in the seal layer is unsuitable. Countermeasure: Adopt the film with good anti-pollution heat sealing.

    In general, LDPE has a medium resistance to pollution heat seal, Eva in the VA content is high when a good anti-pollution heat seal, LDPE also has a good anti-pollution heat sealing, ionic resins and metallocene polymers have excellent anti-pollution heat seal.Plastic Bag Making Machine

    What about the warp after the heat seal? Reason: The thickness of the composite film is inconsistent, the heat sealing temperature is too high or the heat sealing time is too long; in the longitudinal heat sealing knife part, the running trajectory of the composite film is uneven, the cooling is not sufficient, the curing time is not enough, the surface substrate film has poor heat resistance, and the tension matching of the composite substrate is improperly controlled, which leads to the residual stress after the ripening and shaping. Especially when the composite film thickness is thinner, this kind of fault is more likely to occur.Plastic Bag Making Machine
