Causes of uneven deformation of food bags

Let's first analyze the main reasons for the curling and deformation of food packaging bags: 1. The heat resistance of the surface substrate film is poor; 2. The tension matching control of the composite substrate during the compounding process is improper, resulting in its curing and shaping. There is still residual stress, especially when the thickness of the composite film is thin, such failures are more likely to occur; 3. The thickness of the composite film is inconsistent; 4. The cooling is insufficient; 5. The curing time is not enough; 6. In the longitudinal heat sealing knife part, The running track of the composite film is not straight; 7. The heat sealing temperature is too high or the heat sealing time is too long; then we will summarize the countermeasures for these reasons: 1. Re-select the surface substrate film, remember not to be greedy for cheap choices Know a little about the substrate; 2. Adjust the tension of each part of the composite processing equipment, try to make the shrinkage ratio of the two composite substrates the same as possible 3. Adjust the tension of the floating roller during the composite to make the thickness as consistent as possible; 4. Fully cool; 5. Fully mature, but do not make the material overcooked, otherwise it will easily cause adhesion. This degree must be mastered; 6. Select the inner sealing substrate with low temperature heat sealing; 7. Adjust the heat sealing temperature to a suitable temperature .
Every day of the year, there is some city or town in the world that is changing over to for flexible packaging solutions.
Supouches Packaging is the vital link in the supply chain, adding value with efficient and cost-effective service and solutions for our customers and our suppliers.
There are so many factors that businesses have to weigh when producing flexible packaging, and we are not going to pretend to grasp all of them.
There are different types of , mainly flexible packaging solutions and flexible packaging solutions.
