However, the current composite film bags still have the following deficiencies:

[0003] For example, the patent document with the application number 202320697457.7 discloses a foldable composite film bag. When the foldable composite film bag is folded, it only needs to fold the composite film along the side crease and the lower crease. At this time, the buckle structures above the composite film approach and are fixed together by the buckle structures, and then adsorbed together by the magnetic strips on both sides to complete the sealing. However, its barrier property is poor, and it is easy to produce oil leakage and water seepage, and it is easily damaged during use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a high-barrier oil-proof composite film bag is proposed. Content of the Utility Model
