Woven inner bag (3) has an isotactic material, syndiotactic and atactic material was three configurations, industrial products as a main component was isotactic polypropylene also includes a small amount of propylene and copolymers, including ethylene. Usually translucent colorless solid, odorless, non-toxic, is the lightest of the common plastic. corrosion resistance, tensile strength of 30MPa, strength, rigidity and transparency better than polyethylene. The disadvantage is poor low temperature impact resistance mortar plastic bags, representing a too easy to aging of PVC stretch film production cut filaments findings and new technologies split fibers. 1950s, O · B · Rasmussen, through research, the use of stretch film extrusion methods and equipment bags, began producing woven fibers. By 1965, Europe began the industrial production of the one-way stretch flat, for the production of industrial packaging bags. Xiong Xin Yu plastic bags factory strict product quality, professional quality control team, our customers can buy. Woven tensile load. Tensile load, also known as tensile strength, tensile strength. For the warp and weave Booker withstand tensile load zonal both directions, so that the warp and weft tensile load. 4. width. Various woven bag width directly affect processes. For tube by folding cloth, said width, equal to the circumference of a long break by half. Width retraction rate of feed with plastic bags, all woven weaving width after coiling, in unrolled cutting, printing, stitching, the width of the bag should be made slightly smaller than the width of the take-up when we called back width shrink. Stone is a warm encounter explosive dangerous goods, high packaging requirements. There is a multi-layer plastic container bags of white snakeskin bags made of composite materials can be packaged dangerous goods like calcium carbide. Capacity of one ton, the bag from the outside, the inside of three layers, the outer plastic woven bag for Fumo, the inner is polythene film, the middle four to five adapt like calcium carbide composite material consisting of special packaging. This Container has good sealing, high strength and low cost compared to traditional metal pail, reducing transport costs more than 10%, one of only ten powder losses, economic greatly increased.
