Surface protection tape refers to a film tape used to protect sensitive surfaces of various articles from scratches, dust or other damage. Surface protection tapes can be used on new painted metal surfaces, hubs, exterior plastic parts, interior trim surfaces. Temporary protection, etc., to protect the surface of all parts of the car clean, can also be used for temporary or permanent protection of the surface of the various parts of the aircraft, ships, rail locomotives and exteriors.
The surface protection tape is generally a polyacrylate type protective film, which is a separation layer, a printing layer, a film, and an adhesive layer in order from top to bottom. The film is generally made of low-density polyethylene (PE) and polyvinyl chloride (PVC). It can be obtained by extrusion molding, injection molding, and blow molding.
Since polyethylene is cheaper and more environmentally friendly, 90% of the film is made of polyethylene. The main process is blow molding. There are many types of polyethylene, and the melting point and density are different. The key to the quality of the surface protection tape is determined by the properties of the gel. There are two types of pressure sensitive adhesives for the surface protection tape: solvent-based polyacrylate adhesive and water-soluble polyacrylate adhesive, which have different characteristics.
