The conventional automatic laminating machine technology on the market adopts the method of laminating with glue, and 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 is stopped, the PE film can be hot-melted on the color printing paper. After being processed by the automatic laminating machine, it will not bubble when it is rubbed hard, and can withstand high temperatures of about 20 to 120 degrees. In the process of non-glue automatic laminating, a layer of auxiliary materials is placed between the heating roller and the PE film, and passes 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 make light film, matt or other effects. First of all, high-pressure polyethylene blow molding PE film as the main material, that is because of its easy to obtain hot melt and plasticity.
The advantages of fully automatic laminating technology are obvious
First, if he does not use glue, the cost will be reduced a lot, and it is obviously reduced. Especially for the matt film and the laser film, the cost is basically reduced by about 10%.
The second is that he is absolutely safe and environmentally friendly. In the past, those easily volatile harmful gases were very harmful to the human body during use. At the same time, after experiments, the product was placed in a 5% caustic soda solution at 80 ° C. With light agitation, the self-adhesive indentation will show the phenomenon of separation of the film and the paper. The film floats up and the paper sinks, which is easy to recycle.
Third, due to the automatic laminating of the glue, the glue layer is 0.002 ~ 0.003mm after the initial drying, so the powder on the printing paper will appear to be uncompressed, and the product will be uncompacted. snowflake". But the automatic lamination without glue will not, because the film used in this technology is 0.017 ~ 0.02mm thick, and it becomes this thickness of glue in its hot melt state, so it can be used casually with less than half the pressure. No "snowflake" is produced, so there is no need to dust.
