The quality of products is directly related to the selection of raw materials. The quality of raw materials depends on the quality of raw materials and the amount of raw materials added. Therefore, when manufacturing any kind of products, we need to be cautious in the selection of raw materials. Which kind of manufacturer needs a lot of container bags in production, so what’s the standard of material selection for container bags? How can we make container bags with high pressure? Xiaobian wants to share it with you and have a look.
The main raw materials for packing bags are polypropylene, calcium carbonate and anti-aging agents, which are characterized by the anti aging agent: 3,5_ Dimethoxy-4-hydroxybenzoic acid, 3,5_ Dimethoxy-4-hydroxybenzoic acid accounts for 1-5% of the total weight of polypropylene. Calcium carbonate accounts for 5-10% of the total weight of polypropylene, and a UV absorber is added to 3,5-dimethoxy-4-hydroxybenzoic acid, and the UV absorber is o-hydroxybenzophenone. After aging test, the retention rate of warp breaking tensile strength is 70-75%, and that of weft breaking tensile strength is 55-60%. When the packed bag is made of calcium carbonate with 5-10% of polypropylene weight, it has good aging resistance and can be used as raw material for container bags. And it should be noted that the container bags should not be exposed to the sun for a long time, so as to avoid the continuous decrease of tensile strength of polypropylene in container bags.
For container bag manufacturers, only when they produce good quality container bag products, can they enhance their market competitiveness. When making container bags, they should not be careless in the use of raw materials and processing procedures. Only in this way can they produce qualified container bags.
