The window sticking process of the window sticking machine is mainly used in the packaging of carton, gift box, window sticker envelope, etc., so that the product has visibility in the package; the contact between the printed matter and the plastic film is completely dependent on the action of the adhesive, so The performance of the adhesive has a crucial influence on the quality of the finished product; the following is an analysis of the influence of the adhesive on the window bonding process of the window bonding machine:
1. The proportion of binder and thinning water. It must be formulated in strict accordance with the requirements of the film and adhesive, otherwise it will also cause poor adhesion.
2. The viscosity of the adhesive. If the viscosity of the adhesive is too high, its castability and wettability will be reduced, and the adhesive coating will be uneven, which will cause the coating layer to smudge and degumming after lamination. On the other hand, if the viscosity of the adhesive is too thin, the solvent in the adhesive cannot be fully volatilized during drying, which reduces the solid content of the adhesive.
3. The coating thickness of the adhesive. If the coating amount of the adhesive is too small and the thickness is too thin, the adhesive force will be insufficient and the film will fall off easily. However, if the coating layer is too thick, the impact will be even worse: the evaporation of the solvent in the adhesive is slowed down, and the product is easy to foam after being placed; affected by the water content of the paper, wrinkles appear at the window after the paper fiber shrinks, and even in the The rubber ring is extruded at the window sticking machine process. All of these will cause fatal damage to the quality of the coating.
The use of the window sticking machine improves the production operation efficiency. It is used in the packaging product industry. The mechanized production gradually replaces the manual production operation, which greatly improves the quality of the operating products and the consistency of the products. The use of window stickers has a great advantage in production.
