1 Bubbles after lamination, bubbles after aging.

①Due to the high barrier properties of the film, the CO2 gas generated during the curing of the adhesive remains in the composite film, and there are bubbles in the unprinted areas. The amount of curing agent should be increased to allow the adhesive to cure during drying.

②Ethyl acetate in the adhesive is a good solvent for ink binders. The adhesive dissolves the ink, and there are only bubbles on the ink. Avoid water from penetrating into the adhesive and increase the drying temperature of the adhesive to reduce the dissolution of the ink.

2 Irregular wrinkles and bubbles on the composite film

①Uneven film thickness, avoid using films with uneven thickness.

②The film is stretched too much, the shaping is insufficient, the same thermal shrinkage, and due to moisture absorption, the film is deformed. The moisture absorption deformation of the film should be prevented, the printing winding tension should be reduced, and the tension during lamination should not be too high.

3 Regular bubbles and wrinkles on the composite film

Reason: The mesh on the mesh roller is broken, the rubber roller is damaged and dented, there is dirt on the laminating roller, and there is a deviation between the substrate speed and the mesh roller speed, and the film thickness is deviated.

Solution: The mesh roller should be checked, replaced or repaired; check whether the rubber roller is damaged, replace or repair; clean the laminating roller.

4 Foreign objects are included in the composite film, and there are bubbles

Reason: Dust and rubber particles are mixed in the adhesive, dust is attached to the film, and the roller is not clean.

Solution: The adhesive and film should be cleaned, pay attention to environmental sanitation, and clean the roller.

5 Orange peel occurs on the composite film

Reason: Fine powder is mixed in at high temperature, and orange peel is formed under heat and pressure. Anti-static lamination, in the binder, the anti-static agent agglomerates and orange peel occurs.

Solution: Do not use powder coating, reduce the insulation temperature and winding pressure, and prevent the anti-static agent from agglomerating.
