[0002] Packaging bags are a kind of packaging supplies used to pack all kinds of goods. Packaging bags are widely used in life. Anti-counterfeiting information is also printed on the packaging bags to prevent counterfeiters from forging and avoid losses to merchants.

[0003] For example, Chinese patent CN221252329U discloses an anti-counterfeiting composite packaging bag, including an outer layer, a packaging strip for sealing the outer layer is provided on the top of the outer layer, an anti-counterfeiting strip is provided on the top of the front of the outer layer, and a functional component for preventing oil leakage is provided inside the outer layer, and the functional component includes an anti-seepage layer, and the anti-seepage layer is provided on the inner wall of the outer layer. The utility model utilizes the design of the outer layer, the packaging strip, the anti-counterfeiting strip and the functional component. By pressing the packaging strip, the outer layer can be sealed, thereby ensuring that the food inside the outer layer will not fall from the inside of the outer layer, and the oil stains generated inside the food will leak through the PP layer inside the outer layer. Under the blocking of the anti-seepage layer, it cannot continue to leak out, thereby ensuring that the outside of the outer layer is dry, so that the shoppers' hands will not be stained with oil stains, and it is more convenient to hold the outer layer.

[0004] Although the above patent ensures that the outside of the outer layer is dry, so that shoppers' hands will not be contaminated with oil stains and it is more convenient to hold the outer layer, the outer structure of the patented anti-counterfeiting strip is simple and the protective performance is average, which is easily scratched and damaged by human factors, reducing its practicality.
