When people buy cosmetics, they usually see some special bags. The texture of these bags is very durable, generally not easy to be damaged, and the bags do not have any odor and processing marks, and the performance is stable during use. It does not contain toxic substances. More importantly, there is a sealing port on the bag, which can be sealed through the sealing port during use. This bag is actually called a ziplock bag. Nowadays, self-styled packaging bags are not only widely used in the cosmetics industry, but the application of packaging bags can be seen everywhere in the electronic processing industry and food sales.
People pay attention to the application of ziplock bags mainly by taking advantage of the waterproof and moisture-proof characteristics of the packaging bags. Therefore, many manufacturers use ziplock bags for storage when producing electronic components. After sealing the seals, external air and moisture can be avoided. The gas enters the inside of the bag, so the waterproof and moisture-proof effect of the bag is excellent, and it is one of the reasons why the self-sealing bag has been widely valued by users.
