Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to an anti-dumping plastic food packaging bag. Background Art
[0002] Plastic food packaging bags refer to plastic products used to package food. By using specific plastic materials and processing technologies, plastic packaging bags can effectively isolate air and moisture, reduce food oxidation and deterioration, and maintain the freshness and taste of food. At the same time, plastic packaging bags are light and easy to carry, making it convenient for consumers to take food home or eat on the go. In order to prevent the packaging bag from collapsing during consumption, an anti-dumping design must be set to prevent the internal food from flowing out and causing waste.
[0003] Some anti-dumping plastic food packaging bags are generally designed with a cone shape or special grooves at the bottom to help the food be evenly concentrated at the bottom of the bag, thereby reducing the possibility of dumping. When eating, carefully tear open the bag along the tear line at the opening, and then place the bag on the table to prevent dumping and remove the food inside to enjoy.
[0004] Some anti-dumping plastic food packaging bags only have special grooves or conical designs on the bottom. Although they can achieve anti-dumping effects, they cannot be folded as a whole after eating. After pouring them into the trash can, they need to be squeezed additionally to reduce the space occupied by the bag. At the same time, bones, peels or other garbage spit out during the eating process are not stored in proper containers. If they are placed directly on the table, they need to be cleaned up afterwards. If they are spit directly into the trash can, the trash can needs to be close to the diners, which will affect their appetite. Utility Model Content
