Baking packaging material

Abstract

The invention discloses a baking packaging material which sequentially comprises a coating layer, an aluminum foil composite film layer, an adhesive layer, a drawing and winding film layer and a printing protective layer from inside to outside. The coating layer is a chitin fiber coating layer; the aluminum foil composite film layer is a vacuum aluminum-foil-plated flow casting polyethylene film; the adhesive layer is a polyethylene terephthalate film layer; and the drawing and winding film layer and printing protective layer are respectively a cyclopentadiene film. The thickness of the packaging material is 0.5-1mm, and the temperature resistance is 180-200 DEG C. The baking packaging material can be used for hot packaging for baking foods, and can be directly subjected to heat sealing after fowl, bread and other baking foods are formed. By using the reasonable structural design and material selection, the baking packaging material has the advantages of favorable mechanical strength, high temperature resistance, favorable packaging protecting property, no pollution and the like, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a baking packaging material. Background technique [0002] The current packaging method of baked food in my country is to first carry out tray packaging materials, and then use ordinary packaging materials to pack after cooling. This packaging method is not only complicated, but also the food may suffer from bacterial contamination during the cold storage process, and the protection performance of the common packaging materials used is not good, which will eventually affect the quality and taste of baked food. The reason for the above-mentioned packaging problems is that the current tray baking packaging materials have poor mechanical strength and high brittleness, and cannot meet the requirements of direct heat-sealing packaging. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a baking packaging materia...
