The conventional automatic laminating machine technology on the market adopts the method of laminating film with glue. Moreover, the automatic laminating method of the automatic laminating machine is different. The PE film with high-pressure polyethylene as the main material is used. After the special treatment of the film, the PE film can be heat-melted and loaded on the color printing paper. After being processed by the automatic laminating machine, it will not be bubbled after being rubbed hard, and it can withstand high temperatures of about 20 degrees to 120 degrees. , In the process of automatic laminating without glue, a layer of auxiliary materials is inserted between the heating roller and the PE film, and they are passed through the automatic laminating machine together, and then the automatic laminating products are removed from the auxiliary materials. Due to the different materials used, the same kind of PE film can produce light film, matte or other effects. First of all, high-pressure polyethylene is blown into PE film as the main material because of its easy-to-obtain hot melt and plasticity.
The advantages of fully automatic laminating technology are obvious.
First, if he doesn't use glue, the cost is reduced a lot, and the reduction is very obvious, especially for the matt film and the laser film, the cost is basically reduced by about 10%.
The second is that it is absolutely safe and environmentally friendly. The harmful gases that are easily volatilized in the past are very harmful to the human body during use. At the same time, after experiments, the product is placed in a 5% caustic soda solution at 80°C. With gentle stirring, the self-adhesive indentation will cause separation of the film and paper. The film will float up and the paper will sink. It is easy to recycle, so it is a product with a higher green level.
Third, since the glue layer is 0.002～0.003mm after fully automatic laminating and gluing and drying to the initial drying, it will appear that the film is not compacted when encountering the powder on the printing paper, and the product will appear uncompacted and fine. snowflake". However, the automatic laminating film without glue will not. Because the film used in this technology is 0.017～0.02mm thick, it becomes the glue of this thickness in the hot melt state, so it only needs less than half of the pressure to make it casually. No "snowflakes" are produced, so there is no need to rub powder.

The phenomenon of wrinkles in the film, in fact, this kind of problem is common, and because of this, the problem of wrinkles in the film of the film laminator has also become a problem that has been discussed in the post-press processing industry. Next, let's discuss the next thing about the film laminator. Causes and solutions for wrinkles in the film.

What are the characteristics of the ready-to-coat laminating machine?
1. The base and wall panels are constructed of cast iron and are not deformed to ensure that their accuracy will not be affected during use and maintenance and replacement of parts.
2. The gluing roller and the rubber-limiting roller are made with precision, and the concentricity error of the roller surface is controlled within 0.01mm to ensure uniform gluing and save the amount of glue.
