Abstract
The utility model provides a self-heating food packaging cover film, which comprises a base layer, wherein a printing layer is arranged on the outer side of the base layer, and a nylon layer is arranged on the inner side of the base layer; a layer of frosted coating is arranged on the outer side of the printing layer; the inner side of the nylon layer is provided with an antibacterial layer; the self-heating food packaging cover film is provided with a series of through holes from top to bottom; the nylon layer is a blend extrusion film layer of PA6 and MXD6, and the thickness of the nylon layer is 100-200 microns. The self-heating food packaging cover film of the utility model can discharge the internal vapor through the through holes on the packaging cover film in a self-heating state, thereby effectively discharging the excessive vapor generated by heating; the nylon also has good performances of aroma retention, oil resistance, puncture resistance and the like, and the top of the packaging cover film is a rough surface, so that articles placed on the packaging cover film are prevented from sliding, and the safety is improved.
Description
Technical Field
The utility model relates to a packing epiphragma, concretely relates to self-heating food package epiphragma.
Background
In recent years, with the pace of life of people becoming faster, many self-heating foods, such as self-heating small chafing dishes, spicy saucers, sour and hot powders and the like, appear on the market. The product is sought by more and more people due to simple operation, convenient carrying, rapidness and sanitation. Lidding films are part of such self-heating food packaging and require not only good barrier properties but also good heat resistance in use. The shelf life of the product is prolonged, and the safety factor of the using process is also improved. Not only the quality of various products containing the contents is ensured, but also the fragrance of the contents is prevented when the food is used, so that the food can be guaranteed to have better taste when being eaten. At present, self-heating food packaging modes on the market are single, the cover body of the packaging box is mostly designed into an integral cover body, and the surface of the packaging box is covered with a layer of printing film.
Disclosure of Invention
