Interleaf paper is a functional industrial paper designed to separate surfaces and protect product quality by preventing friction, scratching, and contamination. Typically placed between layers of items such as metal sheets, glass, stone, plastic sheets, electronic components, printed materials, and other precision products, it creates a stable physical barrier that minimizes direct contact and surface damage during stacking, handling, processing, and transportation.
Performance Advantages
Surface Protection
Effectively prevents scratches, abrasion, and contamination on the surface of the packaged items, maintaining surface cleanliness.
Prevention of Ink Transfer
Prevents ink offsetting between stacked items.
Easy Peeling
Incorporates wax additives or special surface treatments to ensure the interleaving paper peels off easily and cleanly in automated equipment without damaging the protected surface.
High Cleanliness
Made from pure natural fibers with strict control over ash, metal elements, and particulate matter, meeting the rigorous cleanliness standards of high-end precision manufacturing.
Excellent Cutting Performance
The wax-containing formulation significantly improves cutting performance, facilitating precise cutting of stacked sheets.
Customization
Basis weight, dimensions, surface treatment, and packaging formats can be customized to meet specific customer requirements.

Instructions for Use
1. Compatible tools: Technical pens, drawing ink, pencils, and ballpoint pens; use alcohol-based markers with caution, as ink may bleed through thinner paper.
2. Storage conditions: Store in a cool, dry place away from direct light and high temperatures; the paper can be preserved for a long time without yellowing.
3. Printing compatibility: Supports laser and inkjet printing; for inkjet printing, paper weighing 83g or more is recommended to prevent ink bleed-through.
FAQ
Q: What are the primary functions of interleaf paper?
A: Its main functions include separating layers, reducing friction, preventing surface scratches and product adhesion, minimizing contamination from dust and impurities, and helping maintain the product's surface quality during handling, transport, and storage.
Q: Does interleaf paper have good tensile strength?
A: Yes. Industrial-grade interleaf paper typically requires good tensile strength and tear resistance-especially for heavier-weight varieties-to ensure suitability for automated packaging, winding, stacking, and high-speed processing environments.
Q: What are the storage requirements for interleaf paper?
A: It should be stored in a cool, dry, and well-ventilated area away from direct sunlight; it must also be kept off the ground to prevent moisture absorption.
