Determine the characteristics of items that need vacuum packaging. Because the difference between dry and wet things is whether there is juice, for example, miscellaneous grains are dry things, so try to clean the air when vacuuming. Pickles and the like are all wet things, so try to keep the juice when vacuuming, so as not to affect the flavor of food. Below I will share my own process with you, hoping to help you.

For vacuum packaging food, the materials to be prepared include: plastic bags and straws.

First, put the food in a plastic bag.

Second, prepare a straw.

Third, seal the rest of the plastic bag and leave a small mouth at one end.

Fourth, put the straw through the small mouth, and then suck the air dry with your mouth.

5. Then press the sealing strip of the plastic bag tightly with your hands.

Six, so that food can be vacuum packed.
