I believe that there are many food manufacturers who have encountered more or less rolling packaging packaging and deformed deformation. After using plastic food packaging bag packaging products, the overall roll -ups, twisting of bags, uneven packaging, etc. What are the main reasons for these problems, how should we solve it? Let's briefly introduce these issues:
First of all, the main causes of packaging rolling, deformation, etc.:
1. Poor heat -resistant heat resistance to surface substrates;
2. The tension matching of the composite substrate during the composite process is not properly controlled, resulting in the remnant stress after the maturity and setting, especially when the thickness of the composite membrane is thinner than the thickness of the composite membrane is more likely to occur.
3. The thickness of the composite membrane is inconsistent;
4. Insufficient cooling;
5. Insufficient maturity time;
6. In the vertical heat -sealing knife, the running trajectory of the composite film is not straight;
7. The temperature of the heat seal is too high or the hot sealing time is too long;
Now that we already know the reason, we should make corresponding adjustments to this to avoid unnecessary losses. Here are some of the response methods we summarize:
1. Re -select the surface substrate thin film, remember not to be greedy and cheap to choose a slightly knowledgeable bottom material;
2. Adjust the tension of each part of the composite processing equipment, and try to make the two substrates of the compound compound shrinkage rates equal;
3. Adjust the tension of floating rollers during the compound, so as to be as consistent as possible;
4. Full cooling;
5. Fully mature, but it is not familiar to the materials, otherwise it is easy to cause adhesion. This degree must be mastered;
6. Select internal seal substrates with low temperature and heat sealing;
7. Adjust the heat sealed temperature to the appropriate temperature.
