Substrate classification of double-sided tape:
The double-sided adhesive with substrate is made of cotton paper, PET, PVC film, non-woven fabric, foam, acrylic foam, film, etc., and double-sided uniform coating of elastic pressure sensitive adhesive or resin type pressure sensitive adhesive An acrylic pressure-sensitive adhesive or the like, and a roll-shaped or sheet-like adhesive tape formed on the above substrate is composed of a substrate, an adhesive, and a release paper (film) portion.
No base material:
The non-substrate double-sided adhesive is coated on the release paper (film) material with an adhesive (elastomer type pressure sensitive adhesive or resin type pressure sensitive adhesive, acrylic pressure sensitive adhesive, etc.), and is formed into a roll or sheet adhesive. The belt is composed of an adhesive and a separator (membrane) portion.
It is divided into solvent-based adhesive tape (oily double-sided tape), emulsion-type adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendered adhesive tape, and reactive adhesive tape. Generally used in leather, nameplate, stationery, electronics, car trim, shoe, paper, handicraft paste positioning and other purposes. Hot-melt double-sided adhesive is mainly used in stickers, stationery, office and so on. Oily double-sided tape is mainly used in high-viscosity such as leather goods, pearl cotton, sponge, and footwear. Embroidered double-sided tape is mainly used in computer embroidery.
