Frequently Asked Questions (FAQ) about Release Paper Laminating Machine
1. What is a Release Paper Laminating Machine?
A Release Paper Laminating Machine is a device that is specially used to coat a laminating layer (such as TPX, PE, silicone oil, etc.) on the surface of release paper. It heats and melts the coating material to make it evenly adhere to the substrate, improves the anti-sticking, waterproof, and high temperature resistance properties of the release paper, and is widely used in electronics, medical, packaging, labels and other industries.
