Tape is a product that is commonly used in company packaging and transportation. Do we know how tape is made? Below, we will explain the manufacturing method of tape.

The production method of sealing tape: It is based on the original BOPP film and undergoes high-voltage corona discharge to roughen one side of the surface. After applying glue, it is divided into strips and red rolls, which is the tape we usually use.

Tape adhesive is acrylic resin adhesive, also known as pressure-sensitive adhesive, mainly composed of tincture grease. Tincture lipid is a polymer active substance, and temperature fluctuations have a certain impact on molecular activity. The lipid content of glue directly affects the application of adhesive tape. The initial adhesion force of a normal sealing tape is between ≥ 13 (steel ball size), and the thickness of this tape adhesive is usually 22 microns. It is the thickness that meets the specifications.

Colored tape is used for marking and masking purposes, usually with beige and earthy colors being more common. Some people believe that colored tape is the color of the film, and the original color is the color of the glue. Pinch the adhesive tightly and quickly swing it away, which can pull one side of the adhesive off, and you can see the purity and transparency of the original film.
