Description

A new type of food packaging material

【Technical field】

The utility model relates to the technical field of food packaging, in particular to a novel food packaging material.

【Background technique】

Food packaging materials are essential and important materials in the field of food production. With the continuous development of economy and trade, food packaging materials occupy an increasingly important position in the food industry, and play an increasingly important role in improving packaging quality and reducing packaging costs. At present, more paper and plastic flexible packaging materials are used. On the one hand, due to their limited strength during use, they will be damaged and cannot provide proper protection for the packaged products. On the other hand, it will also be affected by storage after use.

In the existing food packaging materials, there is a lack of anti-oxidation layer, which is easy to cause food deterioration; at present, some food manufacturers use the method of filling inert gas into the packaging bag or adding antioxidants to solve the problem of food deterioration, but this takes up space. Transportation, children eating by mistake will also cause accidents.

【Content of utility model】

The purpose of this utility model is to provide a new type of food packaging material for the defects and deficiencies of the prior art, which has excellent protection performance for the food inside.

In order to solve the existing problems of the background technology, a novel food packaging material of the present invention comprises a kraft paper layer, a polyethylene layer, a polyester layer, a drying layer, an anti-oxidation layer and an aluminum foil layer; the kraft paper layer is used as a base, The upper surface of the kraft paper layer is a polyethylene layer, the lower surface of the kraft paper layer is a polyester layer, the lower surface of the polyester layer is a drying layer, the lower surface of the drying layer is an anti-oxidation layer, and the lower surface of the anti-oxidation layer is an aluminum foil layer. The air holes are evenly distributed on the aluminum foil layer, and the kraft paper layer, polyethylene layer, polyester layer, drying layer, anti-oxidation layer and aluminum foil layer are bonded together by water-based adhesive from the inside to the outside.

As a preferred technical solution of the present invention, the thickness of the kraft paper layer is 30-45 microns.

As a preferred technical solution of the present invention, the thickness of the polyester layer is 5-10 microns.

As a preferred technical solution of the present invention, the thickness of the drying layer and the anti-oxidation layer are equal to 20 microns.

As a preferred technical solution of the present invention, the area of the pores on the aluminum foil layer is 10-20% of the area of the entire aluminum foil layer.

The beneficial effects of the utility model are: the packaging material is green and environmentally friendly, has good water and heat insulation, has an excellent absorption effect on moisture and oxygen in the internal environment of the packaging, greatly prolongs the storage time of the food, and effectively avoids the The presence of microorganisms and oxygen will cause a large number of microorganisms to multiply and food spoilage, the manufacturing process is simple, and it is worth popularizing on a large scale.
