1) The first and second layers of the label do not fit together, and there are air bubbles between the films. This is because the lamination environment is not good.

2) There are bubbles in the film and the product because the film and the product are incompatible.

Solution:

1) Increase the injection temperature

2) There are too many additives in the product material. Reduce the additives and try to ensure that the same material is used.
