Description

Technical Field

[0001] The utility model relates to the field of laminated paper, in particular to composite laminated paper. Background Art

[0002] Laminated paper is a composite material made by coating plastic particles on the surface of paper through a casting machine. The main features of this composite material are that it is oil-proof (relatively), waterproof (relatively), and can be heat-sealed. Different uses take different features: when used to package hamburgers, take its oil-proof properties. For example, McDonald's uses 80-degree edible vegetable oil for 10 minutes without oil leakage. When used for coated paper packaging, take its waterproof properties. When used for packaging in an automatic packaging machine, its heat-sealing property is taken. After searching, the prior art (Announcement No.: CN202322343996.3) is an easy-to-fold laminated paper for packaging food. The article records that "after the utility model wraps the food with the laminated paper body, it uses the reverse pulling of the strap and folding it 180 degrees to bond it with the laminated paper body again, so as to seal the package opening and improve the sealing stability by the pressure of the flange part. The whole operation is simple, the design is reasonable and flexible, and the flange part can also facilitate the removal of the laminated paper body, thereby improving the overall practicality." However, in the prior art, the grease generated when frying food is blocked in the laminated paper, resulting in the problem that the grease is contaminated and adheres to the surface of the food, affecting the taste of the food.
