1. It integrates anti-corrosion and packaging functions. The base material is corrugated paper, which contains no corrosion potential, has excellent physical strength and elongation, and is suitable for machine-wound packaging.
2. The patented sap composite paper is smooth and soft, which prevents the board from being scratched, has low water vapor permeability and has waterproof and moisture-proof functions.
3. The fibers in the patented sap composite paper are arranged in a staggered network with many gaps between them. Water can produce capillary effect through these gaps, so it can greatly retain water.
Therefore, the patented sap composite paper is a good paper, which can be used for packaging, waterproof, moisture-proof and other purposes.
