Title:
PLASTIC BAG
Document Type and Number:
WIPO Patent Application WO/2017/210961
Kind Code:
A1
Abstract:
A plastic bag comprises a bag main body (1) having a sealing end (2) at one end thereof. Sealing lines are provided at the sealing end (2) on the bag main body (1). Two sides of the bag main body (1) extend into the bag main body (1) to form folded areas (10). The sealing lines in the folded areas (10) are curved lines (5), and the curved lines (5) are located at inner boundaries between the folded areas (10) and non-folded areas (11). Because the sealing lines in the folded areas at the sealing end of the plastic bag are curved, when a force is applied to the sealing lines, the force would be spread without concentrating at a location, breaking the sealing line at the location, and tearing the plastic apart at a connection part of the plastic bag. Therefore, when using the plastic bag, the bottom portion of the plastic bag will not be easily damaged, thereby enhancing practical applications.
