[0008] According to the above food packaging film with anti-leakage function, the material of the degradable layer is polylactic acid, and the thickness of the degradable layer is 96 - 102 microns, which is convenient for the packaging film to degrade by itself after being discarded.

[0009] According to the above food packaging film with anti-leakage function, the material of the moisture-proof layer is polyethylene, and the thickness of the moisture-proof layer is 48 - 52 microns, which can reduce the contact between the moisture in the air and the food.

[0010] According to the anti-leakage food packaging film described above, the material of the oil-resistant layer is polyester, and the thickness of the oil-resistant layer is 96-102 microns, which can prevent the leakage of food grease.

[0011] According to the anti-leakage food packaging film described above, the material of the antibacterial particles is silver ions, and the number of the antibacterial particles is multiple and distributed in a rectangular array, which is used to extend the shelf life of food.

The moisture-proof layer 5 is made of polyethylene, and the thickness of the moisture-proof layer 5 is 48-52 microns. The oil-resistant layer 7 is made of polyester, and the thickness of the oil-resistant layer 7 is 96-102 microns.

[0025] Working principle: After the food is packaged, under the action of the moisture-proof layer 5, the moisture in the air can be blocked from contacting the food, thereby avoiding the situation that the food deteriorates or loses its brittleness. And the antibacterial particles 9 inside the antibacterial layer 6 can inhibit the growth of bacteria to the greatest extent, thereby extending the shelf life of the food. At the same time, under the action of the oil-resistant layer 7, the penetration of grease through the packaging film can be prevented, thereby avoiding the situation that it is difficult to clean when the grease leaks and falls on the hand. When it is necessary to heat the food in the packaging film, under the action of the heat-resistant layer 2, the food can be heated without removing the packaging film, thereby improving the practicability. And after the packaging film is discarded, under the action of the degradable layer 3, it can be ensured that the packaging film can degrade by itself, thereby reducing the problem of environmental pollution caused by the discarded packaging film.
