The operating principle of vacuum bag is to take out the air inside the
quilt and clothes, so that the volume is reduced, and the use of atmospheric
pressure to flatten the originally swollen quilt and other items, blocking the
outside air, in order to save space, to achieve dustproof, mildew proof,
moisture-proof, insect-proof role.
However, although it is a vacuum tightening bag, it is not certain vacuum,
now the product is generally the use of vacuum cleaner or manual pumping pump to
remove the air in the bag. Use the exhaust tool to remove the air in the bag and
clothing quilt, so as to reduce the volume and add storage space.

material adhesion is not good, more easy to leak, but relatively soft.
