Plastic woven bag with polypropylene as the main raw material, after extrusion, pull, stretch into flat wire, and then woven, woven and made into bags. Although plastic woven bags are made of a variety of chemical plastics, but its environmental performance is strong, so the damage to people or things is generally small, and the strength of recycling is relatively large;
Plastic woven bag with polypropylene as the main raw material, after extrusion, pull, stretch into flat wire, and then woven, woven and made into bags. Although plastic woven bags are made of a variety of chemical plastics, but its environmental performance is strong, so the damage to people or things is generally small, and the strength of recycling is relatively large;
There are two ways to judge the gloss of woven bags; To improve the surface gloss of plastic woven bag is brightening modification process; The other is to reduce the surface gloss of plastic woven bags for the extinction modification process. In addition to the strict screening of raw materials, the brightening method of plastic woven bags, as well as the later adding brightening method, blending brightening method, shape control brightening method and molding equipment smoothness control, and the secondary processing brightening method and surface coating brightening method; These can judge the merits and demerits of woven bag quality.
Woven bags under sunlight are easy to age and will shorten the service life. Experiments show that the strength of plastic woven bags in the natural environment will be reduced by 25 percent after a week of direct sunlight, and 40 percent after two weeks, so that they can not be used basically. Therefore, the storage of plastic woven bags is particularly important, plastic woven bags should be placed in a cool and clean room storage, transportation should avoid sun and rain, can not be close to the heat source, storage period shall not exceed 18 months.
