Knowledge of suction bag and vacuum packaging bag
1. Inspection of the quality of the pump: put the pump nozzle close to your face, and then pump air. If you feel suction, it means that the pump is good.
2. If there is swelling phenomenon in the evacuated bag, on the one hand, the quilts and other things in the bag will deflate, which will also reduce the vacuum degree; on the other hand, from the physical point of view, there is also a gap in the dense material. Due to the negative pressure, air molecules will "squeeze" into the bag as time goes on, and the vacuum effect will gradually decrease.
3. Leather and down products can be stored in this product, but not completely compressed.
4. Before the clothes are put into the collection bag, the wrapping paper or bag should be removed, otherwise the compression effect of suction bag will be affected.
5. Please dry the clothes in the bag. There is no need to use insect repellents, preservatives, etc., otherwise the purchased items will change color and deteriorate.
6. If there is a crack or a small hole is broken in the bag, ordinary wide edge transparent tape can be used to stick both sides of the bag tightly.
