Laminating machine is a kind of plastic film coated with adhesive and printed with paper as the substrate. After being pressurized by blanket cylinder and heating cylinder, they are combined together to form a paper-plastic product. Its classification can be divided into coating type laminating machine and pre-coating type laminating machine. The coated printed matter has an extra layer of thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter. So how can I reduce the amount of film when covering?



The amount of film used in the laminating machine is mainly related to the operation level, so the general recommendations are:

1. The product to be constructed must be straight. The uneven paper with "fluffed edges" and "tight edges" should be dealt with. "Ruffled" paper can be baked, and "tight edge" paper can be hung.

2. Be sure to wait for the blot to dry before covering, otherwise it will cause blistering or hairiness.

3. Minimize the use of powder spraying when printing, otherwise it will cause emptying and foaming at the pile of powder. The powder spraying should be removed before laminating, the ones with more prints can be hung to remove the powder, and those with less prints can be wiped manually.

4. Pay attention to the direction of paper strands when laminating, especially thick paper, to reduce the curling phenomenon caused by rolling and stretching.
