Easy-tear zippers are popular in the packaging industry because they can be reused and easily opened and torn by the elderly and children. The contents of the bag are filled from behind the easy-tear strip, avoiding contamination of the easy-tear strip and extending the zipper's lifespan. This ensures the freshness and safety of the contents and extends their shelf life. The end of the easy-tear strip can also be firmly attached to the bag body, preventing it from being discarded or torn carelessly.
Structure of Easy-Tear Zipper
The tear-off section overlaps the upper end of another body. Below the tear-off section, there is a strip-shaped protrusion that is symmetrical to the protrusion of the body. During use, after the user tears off the tear-off section, the easy-tear section remains on the top surface of the main body. On the side walls of the main groove opening, a circular arc-shaped engaging section is fixed. The concave part faces the main groove side wall connected to it. The body is provided with a main groove, and a strip-shaped protrusion is set on the upper part of the body. Another body is provided with a male strip, and an arrow-shaped direction is set on the male body facing the female body. The cross-section of the main groove is a fan shape facing the male strip. The lower part of the tear-off section has a strip-shaped protrusion, and the upper end of the other body also has a strip-shaped protrusion, which is symmetrical to the tear-off section. After the user tears it off, the easy-tear section will remain on the top surface of the main body. The protective strip can further enhance the connection stability between the main body and the auxiliary body, and cooperate with the protective strip to further reduce the possibility of external impurities entering the mother body and the groove, causing pollution. The protrusion of the body and one side of the other body are heat-sealed, or bonded with adhesive or ultrasonic welding on the same side to form a foreskin.
Advantages of Easy-Tear Zippers
A protective strip is fixed on the main body side wall opposite the main body. The bottom surface of the protective strip is in contact with the top surface of the easy-tear section. The user can directly open the easy-tear section to quickly and accurately find the gap between the main body and the auxiliary body, and conveniently separate the main body and the auxiliary body. Addressing the shortcomings of existing technologies, the easy-tear section allows the zipper to open quickly. A male strip is fixed on the main body side wall opposite the main body, and a female block is fixed on the main body side wall opposite the main body. The easy-tear section allows the user to quickly find the opening position, improving ease of use.
Applications of Easy-Tear Zippers
Different types of zippers have different applications. With easy-tear zippers, you don't need to open the zipper to pack things. The male claws and main grooves of the double-layer zipper are combined, widely used in various packaging fields such as food, medicine, and groceries. Self-sealing zippers are non-toxic, odorless, and have low density.
