Problems solved by technology

Later, food packaged in aluminum foil composite film was opaque, so that consumers could not see the color and shape of the contents, which was not conducive to consumers to buy, and aluminum-plastic composite packaging could not be heated by microwave, so it was more expensive than plastic film.

Embodiment 1

[0025] (1) Take by weighing 100g nylon 6, 8g poly(methyl vinyl ether / maleic acid) copolymer and 2g stearylamide, mix uniformly, obtain NY layer compound;

[0026] (2) Weigh 100g of cooking grade chlorinated polypropylene, 12g of ε-caprolactone / polyether / propylene oxide terpolymer and 2g of stearamide, and mix them uniformly to obtain the RCPP layer mixture;

[0027] (3) Feed the NY layer mixture and RCPP layer mixture into their respective screw extruders, melt and plasticize, the extruder I zone temperature of the NY layer mixture is 220°C, the temperature of II zone is 230°C, and the temperature of III zone Temperature 240°C, Zone IV temperature 240°C, Zone V temperature 230°C, RCPP layer compound extruder I zone temperature 130°C, II zone temperature 140°C, III zone temperature 150°C, IV zone temperature 140°C, V zone temperature The temperature is 140°C to obtain the melt of the NY layer and the melt of the RCPP layer; the melt is filtered by a filter and then pumped to th...

Embodiment 2

[0029] The difference between embodiment 2 and embodiment 1 is that the anti-blocking agent is replaced with an equal amount of zinc stearate, and all the other operations are identical.

Embodiment 3

[0031] The difference between Example 3 and Example 1 is that the anti-blocking agent is replaced by an equivalent amount of 2-(1H-benzopyrazol-1-yl)acetamide, and the rest of the operations are exactly the same.

Abstract

The invention discloses a processing method of an NY / RCPP composite film for a high-temperature retort pouch, and relates to the technical field of composite films. Nylon and block copolymer polypropylene are used as main materials, an NY / RCPP composite film with a two-layer structure is prepared by adding a processing aid, the prepared composite film has the advantages of both NY and RCPP, the use performance of the prepared composite film is further optimized by adding the processing aid, and the prepared composite film is non-toxic and harmless, has excellent mechanical properties, barrierproperties and heat resistance, and is suitable for being used as a high-temperature retort pouch processing material.

Description

Technical field: [0001] The invention relates to the technical field of composite membranes, in particular to a processing method of NY / RCPP composite membranes for high-temperature retort bags. Background technique: [0002] The high-temperature retort bag is a composite plastic film bag that can be heat-treated, and has the advantages of both a can container and a boiling water-resistant plastic bag. The food can be kept intact in the high-temperature cooking bag, sterilized and heated at a high temperature (generally at 120-135°C), and taken out to be edible. After years of use, it has been proved that it is an ideal sales packaging container, suitable for packaging meat and soybean products. It is convenient, hygienic and practical, and can well maintain the original flavor of food, which is favored by consumers. [0003] Early high-temperature retort bags used aluminum-plastic composite film, generally three layers, with a typical structure of surface layer / adhesive / al...
