The main reasons for the poor sticking of the PVC coating film are as follows:
1. Improper selection of the adhesive, improper setting of the amount of glue applied, and wrong proportioning and measurement, the type and amount of adhesive should be re-selected.
2. The diluent contains alcohol and water that consume NO group, so that the hydroxyl group of the main agent does not react, and high-purity acetic acid should be used.
3. There is dust on the surface of the printed matter, wipe it off with a dry cloth.
4. If the ink layer of the printed matter is too thick, the adhesive coating arrangement should be increased and the pressure should be increased.
5. If the ink layer of the printed matter is not fully or completely transparent, it should be hot-pressed again before gluing, and the adhesive with high solid content should be selected, the thickness of the adhesive coating should be increased, and the temperature of the drying tunnel should be increased.
6. The adhesive is absorbed by printing ink and paper, so that the coating amount is insufficient, and the coating amount should be re-formulated and set.
7. The surface treatment of the plastic film is not enough or exceeds the applicable period, which makes the treated surface invalid, and the plastic film should be replaced.
8. If the pressure is too small, the speed of the vehicle is fast, and the temperature is too low, the temperature and pressure of the film should be increased, and the speed of the vehicle should be appropriately reduced.
