In modern manufacturing, release paper, as a key auxiliary material, is widely used in a variety of fields, including labels, tapes, medical dressings, die-cutting, electronics, and automotive. In the label and tape industries, its importance is particularly self-evident. This article will comprehensively analyze the following aspects: the basic functions of release paper, its applications in the label and tape industries, its performance requirements and selection criteria, and future development trends, to help readers gain a deeper understanding of the value of release paper. If you are a practitioner or purchaser in related industries, please contact Revolve CF Release Paper (email: HarveyXu@revolve-cf.com, website: www.revolve-cf.com) for more professional solutions and wholesale support.
Release paper, also known as "peel paper" or "release paper," is a substrate paper with a specially treated surface that imparts low adhesion. Its primary function is to serve as a carrier or protective layer, providing isolation, anti-sticking, and easy peeling without affecting the functionality of the final product.
Release liner paper typically achieves its "peelability" by coating it with a layer of silicone oil (also known as a silicone release agent). This coating resists chemical bonding with materials such as glue, hot melt adhesive, and UV adhesive, allowing for easy peeling.
Anti-stick protection: Prevents sticking of adhesive products during processing, transportation, and before use;
Facilitates die-cutting: Serves as a support for the substrate during die-cutting;
Extends product life: Prevents contamination of the adhesive layer by dust, impurities, and moisture;
Improve operational efficiency: Automatic lamination, precise positioning, and reduced waste.
Self-adhesive labels are one of the most widely used applications for release paper. Release paper, as a backing paper, serves the following functions:
Maintains label adhesion and integrity;
Provides stable shape during the die-cutting and printing processes;
Enables easy peeling and application by consumers.
In automated labeling lines, release paper must possess excellent tensile strength and flatness to meet the demands of high-speed peeling and precise application.
Almost all types of adhesive tapes, such as double-sided tape, foam tape, hot-melt tape, and medical tape, rely on release paper.
Provides ease of use;
Prevents winding and adhesive contamination;
Improves processing efficiency during the die-cutting process;
Enables precise waste removal and accurate positioning and application.
In precision electronics die-cutting, release paper has extremely high requirements for surface tension, release force, and cleanliness.
Medical Industry: Used in adhesive dressings such as bandages and conductive patches;
Automotive Manufacturing: Used in automated lamination processes for interior trim strips and shock-absorbing foam;
Electronics Industry: Used in die-cutting of touchscreen films, battery labels, and screen protectors.
