Bag manufacturing
The bag making process is the last process in the production of plastic bags. This is also the final inspection process, including complaints on film sheet rolls, so it is a very important process. Even though they are produced in an excellent environment, if they are contaminated or fail inspection during this process, it will be completely meaningless.
However, in many cases, the main process is actually carried out by sub-contractors, and many of these companies are home-grown, so it is difficult to maintain the production environment perfectly.
In addition, as the sales are based on the processing fee for each sheet and the processing fee per sheet is around 10￠, profitability can only be improved by increasing the number of sheets. In short, manufacturers aim to improve the productivity as much as possible and pursue speed.
This has a negative impact on the stability of the seals. Basically, there are very few plants that can handle inspections of food and pharmaceutical plants.
