The products produced by plastic packaging bag manufacturers can be used in many industries, but we have found that bag leakage occurs during use. What is the reason for this phenomenon?

You can generally start from the appearance of the product. If the shape of the product is irregular, the cause of this situation is that external squeezing causes new air leakage and damages the product. At this time, it needs to be replaced immediately, which affects our use. Secondly, we need to check whether there is uneven thickness in the appearance of the product. The carrying capacity may be different, causing air leakage in some areas. This phenomenon generally does not appear in regular aluminum foil package manufacturers.

Plastic packaging bags need to be placed in a suitable environment, which can extend the life of the product and save us a lot of costs.
