Description

Technical Field

[0001] This utility model relates to the field of sealed food bags, and in particular to a double-locking zipper structure for leak-proof food bags. Background Technology

[0002] Food bags are packaging containers used to hold meals. They are made of plastic, paper, and composite materials, and are portable. They include takeout bags and lunch bags. Some are waterproof and heat-insulating. The opening is designed with a zipper or snap button to prevent food from spilling and to maintain temperature. They are used in food delivery and picnic scenarios to provide convenience for carrying and storing food.

[0003] Leak-proof food bag sealing zippers are designed to solve the problem of food leakage during transportation. When delivering or carrying food, bumps can easily cause soup to spill out, polluting the environment and affecting the experience. Sealing zippers form a barrier through tightly interlocking teeth, and the locking structure strengthens the seal, preventing liquid leakage and odor from escaping. They also keep food fresh and improve the safety and hygiene of carrying food, making them a key design feature in food packaging.
