Embodiment Construction

[0024] Such as figure 1 As shown, a cover film that can be retorted and sterilized at high temperature includes a main body 1, and the main body 1 includes a PET layer 11, an aluminum layer 12 and a PE layer 13 in sequence from the outside to the inside, and the PE layer 13 includes a composite layer 131, a middle layer 132 and a heat-sealing layer 133 , the aluminum layer 12 is disposed on the composite layer 131 . A thin film layer 14 is provided between the aluminum layer 12 and the composite layer 131. Through the setting of the thin film layer 14, it is ensured that the aluminum layer 12 is reliably composited on the PE layer 13, and the composite cover film is not deformed as a whole. Effectively improve the overall retort and sterilization performance of the cover film;

[0025] The composite layer 131 includes the following components: 100 parts by mass of low-density polyethylene, 5-15 parts by mass of linear low-density polyethylene, and 1-3 parts by mass of PPA; du...

Abstract

The invention relates to a cover film with high-temperature boiling and sterilization resistance. The cover film comprises a body, wherein the body comprises a PET (polyethylene terephthalate) layer,an aluminum layer and a PE (polyethylene) layer from outside to inside sequentially; wherein the PE layer comprises a composite layer, a middle layer and a heat-sealing layer, the aluminum layer is arranged on the composite layer, and a film layer is arranged between the aluminum layer and the composite layer. The cover film has the advantages that by means of the film layer, the aluminum layer can be reliably composited on the PE layer, the whole composited cover film is not deformed, and the whole boiling sterilization resistance of the cover film is effectively improved, so that the prepared cover film cannot have the quality problems of warping, delaminating, wrinkling and damage after being boiled at the temperature of 121-145 DEG C (including 145 DEG C) for 20-40 min, and the actualuse demands are met.

Description

technical field [0001] The invention relates to a cover film capable of high-temperature cooking and sterilization. Background technique [0002] At present, according to the national standard GB / T10004-2008, the high-temperature cooking film is high-temperature cooking grade when the product use temperature is 121-145°C (including 145°C), and the cover film that can withstand high-temperature cooking and sterilization is used in many food products. However, the existing cover film is prone to warping, delamination, wrinkling and damage after cooking during the production process, resulting in poor overall quality stability of the cover film. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cover film that can be cooked and sterilized at high temperature, so as to solve the technical problem of poor quality stability of the existing cover film. [0004] In order to solve the above-mentioned technical problems, ...
