What to pay attention to when using vacuum packaging bags

　　1. Check the quality of the air pump: put the pump nozzle against your face, and then pump air. If you feel suction, it means that the pump vacuum bag is good.

　　2. If the evacuated bag shows a bulging phenomenon, in addition to the poor sealing, on the one hand, the quilt and other things in the bag will deflate, and the vacuum degree will also decrease; on the other hand, from a physical point of view, No matter how dense the material is, there is also an open space. Due to the effect of negative pressure, the air molecules will be "squeezed" into the bag with the passage of time, and the vacuum effect will gradually decrease.

　　  3. Leather and down products can be stored in this product, but do not completely shrink.

　　  4. Before putting the clothes into the storage bag, the wrapping paper or the packaging bag should be removed, otherwise it will affect the tightening effect.

　　  5. Please fully dry the clothes in the storage bag. There is no need to use insect repellants, preservatives, etc., otherwise it will cause discoloration and deterioration of the purchased items.

　　  6. If the bag has a crack or a small opening, you can use ordinary wide-edge transparent tape to stick it on both sides, and it is enough to fit tightly.

　　  7. Avoid too much water vapor in the bag. If the temperature in a certain place is relatively low, it will condense into water droplets.
