1. Without using glue, the cost will be greatly reduced, and will be significantly reduced, especially the cost of matt film and laser film will be reduced by about 10%. 2. Safe and green. In the past, volatile harmful gases were very harmful to the human body. At the same time, through experiments, when the product is placed under light stirring in a 5% caustic soda solution at 80°C, the film and paper separation phenomenon may occur when the adhesive is indented. The film floats up, the paper sinks, and it is easy to recycle. It is a green product. Since the glue layer of the automatic laminating machine is 0.002-0.003mm after the laminating is dried to the initial drying, the powder on the printing paper will be compressed, resulting in the appearance of small, uncompacted "snowflakes" in the product. But automatic lamination without glue will not. Since the thickness of the coating film used in this process is 0.017-0.02mm, it will become glue of this thickness in the hot melt state. Therefore, less than half of the pressure can be used to prevent "snow", so there is no need to rub powder.
