　 Generally, in the tape structure, the substrate is the carrier used for gluing or printing.

Common base materials

According to the main categories, the base materials of tape can be divided into: film/paper, transparent/opaque, soft or tensile/hard non tensile, high temperature resistant/low temperature resistant, self destructing/self-healing.

Common tape substrates include——

  • Films: PET BOPP、PVC、PP、PE、TPU、 Pearlescent film, synthetic paper
  • Paper: Kraft paper, Hemp paper, cotton paper, textured paper, sulfuric acid paper
  • Other base materials: PE foam, EVA foam, polyurethane foam, mesh cloth, cloth base material, aluminum foil, flannel cloth, elastic cloth, non-woven cloth, glass fiber cloth, chemical fiber cloth
  • Special materials: special paper materials, special film materials, high temperature resistant surface materials, low temperature resistant surface materials, tensile surface materials, self-healing surface materials, self destructive surface materials, optical surface materials


Substrate structure

　　 In the production of adhesive tape, due to the different materials and thicknesses (0.012um to 5mm) of the substrate, the surface of the substrate shall be coated or corona treated.

Coating treatment is different according to the material and glue applied, so as to increase the adhesion of the surface; Corona striking is to destroy the material surface by sparks generated by high-voltage electricity, forming a layer of adhesion on the surface. In general, these two processing methods are to make printing and gluing better.
