Attention should be paid to the following when using food packaging bags:
1. Check the quality of the pump: Place the pump nozzle close to the face and pump in air. If you feel suction, it means the bag is good.
2.If there is a bulging phenomenon in the bag, in addition to poor sealing, on the one hand, the bedding and other things inside the bag will release air, and the degree will also decrease; On the other hand, from a physics perspective, denser data has space. Due to the negative pressure, air molecules will be squeezed into the bag over time, and the degree will gradually decrease.
3. Leather and down products can be stored in food packaging bags, but should not be completely tightened.
4.Before putting clothes into the storage bag, the packaging paper or bag should be removed, otherwise it will affect the tightening effect.
5. Please completely dry the clothes in the storage bag. No need to use insecticides, preservatives, etc. Otherwise, the purchased product will change color and deteriorate.
6.If there are cracks or small holes on the bag, you can use ordinary wide transparent tape to stick it on both sides, and it is enough to stick it tightly.
7. Avoid leaving too much moisture in the bag. If the temperature is relatively low somewhere, it will condense into water droplets.
