Abstract

The invention discloses an oxygen-absorbing active packaging cooking film. The film is of a three-layer composite structure, i.e., an outer surface layer, an intermediate layer and a heat sealing layer from exterior to interior, wherein the outer surface layer is composed of block-copolymerized polypropylene, polyolefin elastomer and an anti-sticking agent; the intermediate layer is prepared fromblock-copolymerized polypropylene, iron-containing oxygen-absorbing masterbatch and synthetic silica; and the heat sealing layer is made of random-copolymerized polypropylene, iron-containing oxygen-absorbing masterbatch and synthetic silica. The film prepared in the invention is transparent overally and does not affect the customer's visual sensation of packaged contents; the film has strong barrier properties and can effectively absorb residual or infiltrated oxygen in the package, so the risk of oxidative deterioration of food is lowered, the color, taste and nutritional value of food are ensured, the shelf life of food is prolonged, and the usage amount of preservatives is effectively reduced; in addition, the film of the invention has good heat resistance and can fully meet the requirements of cooking sterilization at 121 DEG C.

Description

technical field [0001] The invention belongs to the technical field of packaging films, in particular to an oxygen-absorbing active packaging cooking film. Background technique [0002] It is well known that the presence of oxygen in packaging bags can lead to oxidative deterioration of food, thereby affecting the shelf life and shelf life of goods. The traditional solution is to add preservatives to food, although it is effective, but it will cause food safety hazards; or add a small bag of oxygen absorber in the packaging bag, although the effect is better than the former, it not only increases the packaging cost, There is also a risk of being swallowed by children. Vacuum packaging and modified atmosphere packaging are considered to be one of the ideal solutions, but even so, it is still impossible to completely remove and prevent the dissolved oxygen in the packaging bag and the permeating oxygen from the outside. [0003] The prior art discloses the use of high-barrie...
