Bearing inner packaging material of polyethylene plastic tube (box), kraft paper, plain paper, and corrugated polyethylene composite carton, polyethylene or polyethylene plastic film, nylon fastening belt or woven plastic fastening belt, waterproof high strength plastic belt, sacks, etc.. The above materials are required to ensure that the corrosion resistance of the material test.
Principle requirement of bearing inner packing method:
