How to choose a plastic woven bag?

PP woven bags are generally made of recycled materials or raw materials, the price of the two raw materials are completely different, from the perspective of the industry, to see whether the material of the woven cloth is recycled, semi-transparent, or new material, the plastic woven bag produced by the new material is of good quality, can be reused, and the plastic woven bag produced by the raw material is used outdoors for more than 8 months. The quality of the woven bag produced with recycled materials is relatively poor, although the plastic woven bag made of recycled materials still has its application space, such as the plastic woven bag with cement, it does not need to use new materials, choose new materials to do or recycled materials to do, can be determined according to their own situation.

What kind of material is used to make woven bags can be roughly identified by the naked eye, and it also needs to be detected if it wants to be accurately identified. If it can be detected, it is generally necessary to detect its appearance quality (whether there is broken wire, length and width size, weight, cleanliness, stitching quality, diameter and latitude, etc.), tensile load (radial and latitude, seam edge and seam bottom), drop test, heat resistance, health performance, etc., it can also be rubbed hard, if there is no crease after flattening the surface and the quality is good, the feel is brittle. You can also look at the thickness, density, pull and look at the tension, the tension of the woven bag containing recycled material is significantly low, if you add a second return material, then the relative tension is lower. The elongation at break is unstable and decreases with the amount of recycled material added.

The brittleness of recycled woven bags has increased significantly, especially the brittleness resistance at low temperature is worse, the impact resistance is decreased, the electrical insulation is decreased, the aging degree is increased, and the speed is accelerated. We can also shake to see if there is debris, the last point is the smell, smell and see, recycled plastic woven bags are made of waste plastics, industrial waste and other processing, the color is mostly cloudy, feel not good and there is a strong plastic taste (bad smell). At the same time, the price of new materials is relatively high, for the packaging of disposable items, it is not cost-effective, the price is high, it will increase the cost of products, for some builders, plastic woven bags made of recycled materials is undoubtedly a good choice, after all, it is not used to dress food, will not cause harm to people.

Why choose pp woven bags: Everyone knows that cement is heavy and that cement will hurt the body and skin, so we have to use plastic woven bags, which can not only be loaded and loaded, but also isolate and prohibit air transmission to prevent its threat to the human body; Everyone knows the importance of food, so we can choose plastic woven bags, we must pack the food, to prevent the food from moisture, rot, but also conducive to food moving and photosynthesis, and prevent rats from biting; Everyone knows the contribution of chemical raw materials to society, our attention to chemical raw materials has always existed, we can not put it into the box, can not be placed in the workshop, neither can be placed in the sun, nor can the wind and rain, so we need to use pp woven bags.
