This is an innovative product with sustainable packaging which has obtained the international invention patent PCT/CN2020/124891.

The specific features are as follows:

1. The vacuum pump adopts an fully-plastic organ structure spring. The inner hole of the spring can be the content channel used to replace the stainless steel compression spring, which greatly optimizes the structure of the pump head and saves space. This is a new attempt;

2. It can meet the strict test requirements of air leakage and water leakage. On the other hand, it can also meet the requirements of soft plastic and the matching requirements of soft bags, so that the contents do not leak or oxidize, can be applied to high-end packaging materials such as food and cosmetics. The tubes, film bags, and bottles are matched into a single material package, which is convenient for the recycling and reuse of packaging materials in the future, and is an inevitable trend of future packaging.
