The main factors affecting the quality of the coating are: 1. Ink It is necessary to use a pre-film coating product. When printing, it is better to use bright light and quick-drying ink for printing. However, it is not appropriate to put more catalyst in use, otherwise the surface of the ink layer will be crystallized. In addition, ink viscosity, oil content, etc. will affect the coating effect. 2. Adhesive coating The adhesive layer on the BOPP film is required to be thin and uniform. Under the premise of ensuring firm bonding, the precoat film with a thinner adhesive coating should be selected as far as possible, otherwise it will affect the melting effect. Laminated film common problems and solutions 1. The product appears snowflakes (1) The pressure of the rubber roller is not enough and the pressure should be increased appropriately. 2. Product wrinkles (1) The pressure of the rubber roller is so large that the film is deformed and the pressure should be properly reduced. 3. Cut product after crimping (1) If the film tension is too large and the film is stretched and deformed, adjust the tension screw to the film. 4. Insufficient adhesiveness, film release (1) The precoat film exceeds the shelf life and replace the new precoat film.
Major media and medical research continue to remind people that a sedentary lifestyle is closely related to many health risks, such as back or neck pain, high blood pressure, heart disease, and obesity.

(2) The glue on the precoat film is not completely melted and can be solved by the following method.
1 Increase the film temperature properly.
2 increase the contact area between the film and the heating roller, so that at the same speed, the adhesive on the film heat to increase the degree of melting.
3 Reduce the film speed.
(3) Dust and impurities on the coating surface of the precoat film shall be promptly removed.
(2) The surface of the rubber roller is damaged and uneven, and the rubber roller should be replaced.
(3) The pressure imbalance between the rubber roller and the heating roller should be properly adjusted.
(4) The tension on both sides of the film is inconsistent, or there are wavy edges. Replace the film material.
(2) The winding tension is large, so that the film and the paper are deformed at the same time, and the winding tension mechanism should be adjusted.
(3) Humidity in the environment should be controlled at about 60% of the humidity in the production plant.
(4) The drying time is short, and the drying time should be appropriately extended. After the film product is completely dried and cooled on the winding roller, the film is cut.
(2) The ink on the printed matter is not dry, and the drying time of the printed matter should be extended, especially when the special printed matter is coated.
(3) The pressure of the coating film is small, the speed is fast, and the temperature is low. The pressure of the film can be appropriately increased, the speed of the film can be reduced, and the temperature of the film can be increased.
