Why can masking paper stick to things? Of course, because it is coated with a layer of adhesive on the surface! The earliest adhesives came from animals and plants, and in the nineteenth century, rubber was the main ingredient in adhesives; In modern times, a wide range of polymers are used. Adhesives can stick to things because of the bond formed between the molecules themselves and the molecules to be connected, and this bond can firmly bond the molecules together. The composition of adhesives varies according to different brands and types, and there are various polymers.
BOPP tape introduction: BOPP (biaxially oriented polypropylene) tape is an indispensable product in any enterprise, company, personal life, the country does not have a perfect standard for the BOPP tape industry, there is only one industry standard "QB/T 2422-1998 BOPP pressure sensitive adhesive tape for sealing".
BOPP tape is based on the original BOPP film, after high-voltage corona, the surface of one side is rough, and then after being coated with glue, it is divided into small rolls after slitting, which is the BOPP tape we use daily. BOPP tape glue is an acrylic glue, also known as pressure-sensitive glue, and the main ingredient is tincture. Tincture lipid is a kind of polymer activity substance, and the temperature has a certain effect on the molecular activity. The tincture content of the glue directly affects the use of masking paper. The initial tack of normal sealing masking paper is between No. ≥ 13 (steel ball size), and the thickness of this masking glue is generally 22 microns. It is the thickness that meets the standard.
According to its efficacy, the tape can be divided into: high-temperature tape, double-sided tape, insulating tape, special masking paper-pressure-sensitive masking paper, die-cutting tape, anti-static tape, anti-static warning tape, different effects are suitable for different industry needs.
