In the packaging industry, paper laminating technology is a very important production process. It can make the paper have higher durability, waterproof and moisture-proof performance and better display effect. The twin-screw extrusion release paper laminating machine is the key equipment to realize this process.
First, let’s take a look at twin-screw extrusion technology. It uses two screws that cooperate with each other to complete the processes of heating, melting, mixing, extrusion and coating. One of the screws serves as a feeding screw, feeding raw materials (such as plastic particles or liquid materials) into the machine head for heating. The other screw serves as an extrusion screw, extruding the molten material from the machine head, and spraying the paint evenly onto the paper surface through the nozzle to form a thin film.
The technical characteristics of paper laminating machines make them widely used in packaging, printing and other industries. For example, in the packaging industry, paper lamination can be used to produce paper or paper products with waterproof, moisture-proof, barrier and other properties, such as food packaging bags, medical packaging boxes, etc. In the printing industry, paper coating can improve the printing resistance, gloss and hiding power of paper, thereby achieving more exquisite printing effects.
In short, the twin-screw extrusion release paper laminating machine is an efficient, environmentally friendly, and intelligent production equipment that has broad application prospects in packaging, printing and other industries.
