Problems solved by technology

[0002] There are many kinds of packaging bags commonly used in daily life. Generally, the corners are right-angled corners, and the easy-to-tear openings are mostly wedge-shaped easy-tear openings. Because many packaging bags are made of hard materials, relatively sharp edges and corners are formed on the surrounding corners of the packaging bags. (right-angled corners), or in the process of tearing the easy-to-tear opening to open the packaging bag, it is easy to form sharp edges and corners at the tear opening, which is likely to cause harm to the human body that comes into contact with it. It can cause great damage to the skin,
