Unbleached Anti Rust Kraft Roll Paper 40gsm for PV Glass Interleaving

Glass interleaving paper is a specialized type of paper used in the manufacturing process of glass substrates, particularly for flat panel displays like PV Glass, LCDs and OLEDs.

Glass interleaving paper serves several important functions in the production and handling of glass substrates. Its primary role is to prevent contamination and scratches on the surface of the glass during transportation and storage. By being inserted between two glass substrates, it acts as an intermediate sheet that reduces the occurrence of glass plate tarnishing and other types of damage.

The composition of glass interleaving paper varies, but it typically includes materials such as chemical pulp, natural pulp fibers, and sometimes specific additives. For example, some interleaving papers may have a controlled amount of sodium content, which can affect the paper's performance and the glass substrates it protects. The physical properties of glass interleaving paper are also crucial for its functionality. These include parameters such as basis weight (usually between 20 to 50 g/m²).

• Scratch protection: Prevents surface scratches and micro-abrasions during handling and transport.
• Shock absorption & friction control: Reduces edge damage and keeps glass sheets from sliding or chipping.
• Moisture absorption: Helps preserve glass quality during storage and transport.
• Supports automation: Allows easy separation of glass sheets in production lines.
• Environmental and recycling: A more sustainable alternative to plastic film or foam.
