What is a release paper?

Release paper is a special paper widely used in packaging, printing and industrial production. Its main function is to avoid the adhesion between the product and the mold or equipment in the production process and ensure that the product can fall off smoothly. In addition, the release paper can effectively protect the surface of the product from damage.
The application scope of release paper includes the packaging of various products, printing after coating the surface of products, and process control of related industrial production lines.

Scope of application:

1.Electronic industry: Release paper is widely used in electronic industry, mainly to prevent prepreg from sticking and protect it from pollution.
2.Automobile foam industry: release paper plays an isolation and protection role in the manufacturing process of automobile foam.
3.Printing industry: Release paper is also used in printing industry, which mainly plays the role of isolating and protecting printed materials.
Adhesive, medical, construction, stationery, advertising, food, composite materials and other industries: these industries also use a large number of release papers to meet their specific production and packaging needs.

Uses:

1.Prevent adhesion and protect: The main function of release paper is to prevent sticky materials such as prepreg from sticking and protect its surface from contamination.
2.Isolation: Release paper plays an isolation role in many industries, such as as a carrier in the production process of tape to prevent tape from sticking to machines or other materials.
3.Food industry packaging: Glassine silicone oil paper, with its high temperature resistance, moisture resistance and oil resistance, is often used in food industry packaging.
4.Other specific uses: For example, in the coating and foaming process of PVC wallpaper and PVC leather, release paper plays a role in carrying.

Classification:

Release paper can be classified into plastic release paper and non-plastic release paper, and can also be classified into silicone release paper and non-silicon release paper according to release agent. Plastic release paper is mainly used to prevent the release agent from penetrating into the paper, and it needs to be coated with plastic (such as film coating). Plastic-free release paper, such as Grazing paper, has good compactness after special treatment and is suitable for die-cutting processing plants.

Purchase suggestion:

When choosing release paper, we should mainly consider the production process, the use of the prepared products, the material, thickness, elongation and the difference between single and double sides of the release paper.
