Manufacture method of microwave direct heated food bag

Abstract

The invention discloses a manufacture method of a microwave direct heated food bag. The manufacture method comprises the following steps: selecting a polyester film PET (polyethylene glycol terephthalate) as an outer film and selecting a polyethylene film PE as an inner film, wherein the inner film has a thickness of 0.035-0.045 mm and the outer film has a thickness of 0.005-0.015 mm; printing a required image-text on the outer film; uniformly stirring polyurethane glue and ethyl ester according to a mass ratio of 1: (1.1-1.3) to obtain an adhesive, applying the adhesive to the inner film, not applying the adhesive at intervals of 8 to 10 mm width on the inner film, and adhering the printed outer film to the inner film by a compound machine so as to obtain a double-layer adhesion film, wherein the adhesive has a thickness of 0.002-0.004 mm; by a disc hole sawing machine, sawing a row of sawtooth holes in the inner film, where the adhesive is not applied; placing the double-layer adhesion film into compound bag manufacture equipment to bake to enable the adhesive to be cured into solid from liquid so as to obtain a composite film; manufacturing the composite film into the package bag by a bag manufacture machine through 4 Pa high-pressure high-temperature heat sealing. According to the invention, the production process of the microwave direct heated food bag is safe and nontoxic and is beneficial to body health of workers; bagged products can be directly placed into a microwave oven to be heated.

Description

technical field [0001] The invention relates to food bags, in particular to a method for making food bags directly heated by microwaves.

Problems solved by technology

At present, the quick-frozen seasoning food on the market must be opened in the packaging bag, and the food must be taken out and put into other microwave oven special containers for heating, or the bag is torn a small hole and then placed in the microwave oven for heating. The bagged products must not be placed directly Put it in the microwave oven to heat, otherwise there will be a danger of the bag bursting

[0004] It turns out that traditional packaging bags are very inconvenient to use and have certain dangers
