1. Uneven substrate thickness
The uneven thickness of the base material will inevitably affect the packaging of the Vacuum packing bag. Therefore, the uniform thickness of the base material should be ensured during packaging so that the wrinkling problem of the packaging bag can be effectively avoided during packaging.
2. Substrate unwinding deviation
In order to ensure that it does not deviate during transmission. The best way to solve this problem is to adjust the position of the film, which can effectively avoid the wrinkling problem of Vacuum packing bags.
3. Excessive or insufficient adhesive application
Because the problems caused by coating are relatively easy to solve, consult experienced people to inform them of the normal coating specifications, and then evenly apply the adhesive and adjust the amount of adhesive. This can effectively solve the problem of uneven coating.
4. Insufficient drying of adhesive
Insufficient drying of the adhesive can lead to a decrease in adhesion and displacement of the two composite substrates. So we should make the adhesive fully dry and adjust the process parameters. Reducing the residual amount of solvent will solve the problem.
5. The composite film is directly wound without cooling or insufficient cooling
If the composite film is directly wound without cooling or if the cooling is insufficient, we should wait for the composite film to fully cool before winding.
The reasons for wrinkling of Vacuum packing bags are mainly reflected in the above aspects. If people want to avoid wrinkling of Vacuum packing bags, they should pay attention to the above problems, so as to ensure the integrity of Vacuum packing bags.
