Although the prohibition of solvent-based coating film technology has been promulgated for many years, there are still many small coating plants in my country that continue to use. It is understood that this process mainly has the following problems.
(1) AFFECT THE HEALTH OF OPERATORS, AND HAVE FIRE HAZARDS
Solvent-based coatings, due to the use of benzene-containing solvents, harm the health of operators and cause great pollution to the workshop environment. At the same time, as the concentration of the surrounding organic solvents continues to increase, it is extremely easy to burst into fire due to static electricity generated by the film material. Moreover, to the surrounding environment, the film-coated factory itself is a serious source of pollution with potential dangers.
(2) LAMINATED PAPER AND FILM MATERIALS ARE DIFFICULT TO RECYCLE AND WASTE RESOURCES
It is understood that 80% of the sources of papermaking fibers in our country now rely on recycled waste paper, including paper wool and paper edges. In printed matter, the amount of paper used for book covers is also huge. If a large number of films are used (especially instant-on film materials), and the paper and plastic film cannot be separated, the waste paper and paper edges covered by the film, Paper wool will not be recycled and cannot be degraded, which will bring inestimable economic losses, which is actually a waste of resources.

The automatic conveying mechanism can ensure that the printed matter does not overlap and enter the composite part equidistantly during transmission. Generally, pneumatic or frictional control is used to realize the control. The conveying is accurate and high-precision. It can also meet the above requirements when the printed matter is composited with a small format.

What is the laminating process of the laminating machine? The laminating process is a surface processing technology after printing, and it is also called post-printing plastic, post-printing glue or post-printing film. It refers to the use of a laminating machine to cover a layer of 0.012～0.020mm on the surface of the printed product. Thick transparent plastic film to form a paper-plastic integrated product processing technology. Generally speaking, it can be divided into two types, namely coating film and pre-coating film, according to the process used. According to the different film materials, it can be divided into two types: bright film and matt film.

Laminating technology is widely used in all kinds of packaging and decoration printed matter in our country, books and periodicals of various binding forms, booklets, calendars, maps, etc. It is a very popular printing surface processing technology.
