How to distinguish the good and bad of the sealing tape
The Internet has changed the way of life, and the use of scotch tape in online shopping is penetrating all aspects of people's lives. While the express delivery industry is developing rapidly, it has also brought a larger market to the tape packaging industry.
Sealing tape is also called bopp tape, packaging tape, etc. It is based on BOPP biaxially oriented polypropylene film, and is evenly coated with pressure-sensitive adhesive emulsion after heating to form a 8μm----28μm Adhesive layer, forming BOPP tape master roll is an indispensable product in light industry enterprises, companies, and personal life.
Today, the editor will take you to understand how to choose a tape that is really good and bad:
1. Look at the total thickness of the tape
2. Look at the tension of the tape
3. Look at the glue (that is, stickiness) of the tape
4. Look at the peeling force of the tape
Another way is to take a piece of tape and seal it on the box to see if it is easy to warp, whether it is easy to break, and whether the surface of the carton can be damaged after tearing. There are two standards for the quality of the glue of the polypropylene tape in use, one is the initial adhesion force, the other is the holding force, and the two are inversely proportional.
