Principles of crepe paper
Why does crepe paper to things? Of course, it is coated with a layer of adhesive relationship! The earliest adhesives came from animals and plants. In the 19th century, rubber was the main ingredient of adhesives. Modern polymers are widely used. Adhesives hold things together because of the bonds that form between the molecules themselves and the molecules that hold them together. The composition of adhesive, according to different brands, different types, there are a variety of different polymers.
BOPP adhesive tape: BOPP (bidirectional drawing polypropylene) adhesive tape is any enterprise, companies, personal life indispensable supplies, the country for BOPP adhesive tape industry has not a perfect standard, only one industry standard "QB/T 2422-1998 BOPP pressure-sensitive adhesive tape sealing".
BOPP tape is on the basis of the BOPP original film after the high voltage corona to make a surface rough and then coated with glue after the strip into small volumes is our daily use of BOPP tape. BOPP adhesive tape is acrylic glue, also known as pressure-sensitive glue, the main ingredient is tincture fat. Tincture tallow is a kind of macromolecule active substance. The tincture fat content of the glue directly affects the use of the paper. The initial adhesive force of the normal sealing paper is no. 13 (steel ball size). The thickness of this paper glue is generally 22 microns. Is a standard thickness.
The adhesive tape can be divided into: high temperature adhesive tape, double-sided adhesive tape, insulating tape, special paper - pressure sensitive adhesive tape, die-cutting tape, anti-static tape, anti-static warning tape, different functions for different industries.
