The HDPE Skin protection Sheet (steel coil corflute protection board) primarily serves for manual packaging of coils and sheets. These materials work in conjunction with several types of edge protection in the range of steel coils. The HDPE skin Protection sheet is made from a high crystallinity, non-polar thermoplastic resin. This material offers excellent resistance to most life and industrial chemicals. Additionally, it provides good chemical stability, allowing it to resist most acids, alkalis, organic solvents, and water erosion.
The HDPE skin Protection sheet features a good waterproof steam function and can be used for various packaging purposes. Moreover, it exhibits good impact resistance, even at low temperatures, such as -40°F.
