(Precautions for use) ● Depending on the home appliance model, the suction power may be weak and a vacuum state may not be achieved successfully. In that case, using a drain net at the entrance may help to create a vacuum. Please search online for more information. ● If you do not need a vacuum state, you can simply seal the bag with a general sealer. ● Home vacuum packaging machines, such as FoodSaver, which compensate for weak suction power with the bumps on the inside of the bag, may not provide sufficient sealing strength. In that case, using a drain net at the entrance may help to create a vacuum. Please search online for more information. ● When purchasing, please be sure to compare the thickness of the bag with the bags you have used before to determine if the strength is sufficient.
