There are three kinds of raw materials used in the production of plastic woven bags, one is recycled material, one is translucent material, and the other is brand new material. Among these three kinds of raw materials, the cost of recycled material is the lowest, so many users are using it. In order to ensure the quality, we should pay attention to some problems in the production, especially in the process of wire drawing. What problems should we pay attention to?
When passing through the tee, it should be filtered. When selecting the filter screen, generally 15-30 layers should be selected, because too little will cause unstable material flow, resulting in low product density and too much resistance.
We can also determine through practical experience that after filtering, the material activity can be stabilized and the impurities in it can be filtered out, so that the density of the color printing woven bag will be higher, although the recycled material can be recycled After filtering and processing, the quality of the product is far inferior to that of the woven fabric made of brand-new materials. Its longest outdoor life is about 8 months. If it is used for a long time, it is recommended that you buy brand-new products from the plastic woven bag manufacturer.
