The superior performance of vacuum bags!

Compared with ordinary packaging bags, vacuum bags have superior performance, which can not only prolong the shelf life of goods, but also ensure that their taste remains unchanged. This is because the packaging bag has a special function of use. For example, the vacuum bag must have very good sealing performance, that is, high barrier performance against air and moisture. The components of the barrier are water, oxygen and carbon dioxide, so that the product can be protected in a completely isolated environment. This high-barrier material As a co-extruded film, it has relatively stable properties and has a very good resistance to moisture and oxygen. The vacuum bag does not add harmful substances as additives in the manufacture, and will not cause pollution to the goods. In this regard, it is better than ordinary plastic bags.
