Fireproof Gypsum Liner Paper

Fireproof gypsum liner paper is a specialized paper liner used in the production of fire-rated gypsum board. It wraps and supports the gypsum core, helps maintain board strength during continuous manufacturing, and gives fire-rated boards their clear red or pink visual identification. For gypsum board manufacturers, the right liner paper is not just a covering material. It directly affects bonding performance, drying consistency, board appearance, machine speed, and final product stability.

What Is Fireproof Gypsum Liner Paper?

Fireproof gypsum liner paper is engineered for the face or back side of fire-rated plasterboard and drywall products. Compared with standard gypsum board paper, this grade is designed to offer a more stable fiber structure, reliable tensile strength, moderate air permeability, and dependable adhesion to the gypsum core. In real production conditions, that means fewer paper breaks, smoother board forming, more stable drying, and better running performance on automated gypsum board lines.

At Jiayi Paper, our fireproof gypsum liner paper is made from high-quality recycled wood pulp that is sorted, purified, and processed for clean, stable production performance. The available grammage range is 140gsm to 180gsm, and we support customization for gsm, width, roll diameter, and color to match different board specifications and machine requirements.

Why Fireproof Gypsum Board Manufacturers Choose This Paper

When buyers search for fire resistant gypsum board paper or fire rated plasterboard liner, they usually care about five things most:

1. Stable red or pink color: Fire-rated gypsum boards are commonly identified by a red or pink paper liner. A stable, non-fading color helps with product recognition, grade differentiation, and market consistency.

2. Strong gypsum adhesion: A well-designed liner paper bonds firmly with gypsum slurry, helping reduce delamination risk during production, cutting, stacking, transport, and installation.

3. Balanced strength and porosity: High tensile strength supports high-speed automated production, while moderate air permeability helps moisture release evenly during the drying process.

4. Smooth and practical surface quality: A clean and even paper surface supports better board appearance and improves the overall finishing performance of fire-rated gypsum board.

5. Customization for production efficiency: Different factories use different line speeds, widths, and core sizes. Customized liner paper helps improve line stability, reduce waste, and support long-term bulk purchasing plans.

Main Applications

Fireproof gypsum liner paper is mainly used in the manufacturing of fire-rated gypsum board for:

• partition wall systems

• ceiling boards

• shaft wall panels

• stairwell protection systems

• schools, hospitals, offices, warehouses, and public buildings

• commercial and industrial projects with fire-safety requirements

Because fire-rated plasterboard is widely specified in commercial construction and public infrastructure, manufacturers increasingly need liner paper that combines consistent quality, bulk supply reliability, and flexible customization.
