1, has a good fluidity good flow properties to film uniformity, film thickness uniformly coated. Since the coating die long woven bags plant in Hebei, especially reentry coated on both sides of the long die once, double head, wide tarpaulin with a die, the material melt flow in the die long distance, through time relatively long resistance in the die is large, do not choose a good resin flow can cause a film of uneven thickness ranging from Hebei bags, flow rate, temperature of the die lip is not like, there will be a partial first Cooling lose viscoelastic Hebei bags prices, and woven adhesive is not strong. Flowability index is a measure of the melt index M1, in general, the polyethylene is 4 ~ 15g / 10min, polypropylene 7 ~ 30g / 10min more appropriate. 17, after the cloth take the small roll diameter, (if manual transmission) tension to run. 18, when changing specifications, rubber roller and a pressure roller surface prior decontamination. Hebei bags, Xin Yu packaging, Hebei bags provided by Xiong Yu Xin plastic packaging plant.
