  • Check the tightness of the bag 

To protect the food inside well, it is necessary to ensure the tightness of the bag. Make sure the bag has a secure zipper. Especially for fresh food or drinks, the sealed zipper bag will prevent liquid from leaking out.

Zipper bag thickness is also a factor you should consider when buying. If using zipper bags to store frozen foods, choose thick bags, preferably with a thickness of 0.07mm or more. If you choose a zipper bag that is too thin, your food inside will likely be oxidized by the outside air even though the bag is closed.

  • Heat resistance test

You should test the heat resistance of the zipper bag to be sure that it can be used in hot water to defrost food or use in the microwave.
