How to deal with the quality problem of plastic packaging bag (2)？

We have discussed the sealing problems of coffee packaging bags and the leakage of vacuum packaging bags. In the actual production, plastic packaging bags, whether used or produced, will have a variety of problems. Next, let's see what other problems there are.

First, the emergence of layer phenomenon. Generally speaking, the first thing to consider is that plastic bag manufacturers have problems in the compound link, there may be composite temperature can not reach, there may be composite glue problems, there may be composite time is not enough, and so on. When encountering this problem, you need to communicate with plastic bag manufacturers first.

Two, sealing position or easy to tear position is inappropriate. Most of these problems are caused by the lack of consideration in the design of plastic packaging bags by plastic packaging bag designers. As a result, the sealing part of printed plastic packaging bags seals the product information, resulting in incomplete product information display, or the easy-to-tear position is too close to the middle or the two ends, which brings inconvenience to the use of consumers. Therefore, we need to design the size data of the packaging bag in advance.

Three, the content does not fulfill the obligation to prompt safety. The most common situation is that customers custom-made aluminum foil material high temperature resistant vacuum packaging bags, used to pack cooked food, originally is open bag ready-to-eat food, but some consumers still want to heat food, at this time, if there is no prompt on the outer packaging bag: "No microwave oven heating" words, it may cause safety accidents. There are also some allergen information, heating time and temperature information, and so on. If the printing of plastic bags should be prompted but there is no prompt, it may cause problems. When encountering such problems, we can only give up the use of this batch of plastic bags and re-customize more standard plastic bags.
