In the current market, there are a lot of goods without sealing packing design, such as the food packaging that is basically the plastic or paper material. When half of the food is eaten, the bag can not be sealed and lead to the air entering the bag to make food spoiled.
This design aims to settle the above problem. The overall shape of the product is simple like a leaf. After opening it, two ends can be fixed on the packing bag in order to cut off from the air and to ensure the quality of the food.
