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
The present invention relates to food bag, be specifically related to the method for making of the direct heated food bag of microwave.
Background technology
Quick-frozen seasoned food has the features such as safety, nutrition, health, convenience, since nineteen twenty-eight is since the U.S. takes the lead in releasing, has been favourably welcome.Through over half a century development, quick-frozen seasoned food has become one of industry with fastest developing speed in food service industry.In developed country, along with popularizing of houshold refrigerator and micro-wave oven, quick-frozen seasoned food is over nearly 10 years, with the speed increase of annual 10%-13%.
Along with the raising of China's living standards of the people, the quickening of rhythm of life, refrigerator universal, and micro-wave oven progressively enters family, the quick-frozen seasoned food market potential of China is very large, it is predicted, to 2015 Nian， China quick-frozen seasoned food demands, can reach 1,000 ten thousand tons.At present, quick-frozen seasoned food on market must open the package, food taking-up is put into other micro-wave oven special containers heats, or sack is torn and put into that micro-wave oven heats after an osculum again, definitely bagged product directly can not be put in micro-wave oven and heated, otherwise just there will be the dangerous situation of sack explosion.
Originally, traditional packaging bag was used very inconvenient, and had certain danger.
Summary of the invention
The object of the invention is to: the method for making that the direct heated food bag of a kind of microwave is provided, adopt the principle of heating of micro-wave oven, utilize the different ventilation of the plastic sheeting of unlike material, the feature of high temperature resistant, low temperature, the food bag of being made by the method directly is put into product in micro-wave oven and is heated together with sack in the situation that not opening or tearing packaging bag, to face the progressively processing of microwave food prevailing and the needs of use!
Technical solution of the present invention is that the method for making of the direct heated food bag of this microwave comprises the following steps:
(1) selecting mylar PET is adventitia, and polyethylene foil PE is inner membrance; Interior thickness is 3.5-4.5 silk, and outer thickness is 0.5-1.5 silk;
(2) picture and text that printing needs on adventitia;
(3) polyurethane glue and ethyl ester 1:1.1 ∽ 1.3 adhesives that stirs to obtain in mass ratio, upper adhesives is to inner membrance, and the thick 0.2-0.4 silk of adhesives is not gone up adhesives at interval of 8-10MM width on inner membrance, the adventitia printing and inner membrance is bonding by compounding machine, obtain double-deck bonding film;
(4) with disc saw hole machine, saw a row with the sawtooth hole of spacing not going up on the inner membrance of adhesives; Or directly the 8-10MM centre portion that there is no adhesives is marked to an inner membrance line and guarantees that adventitia is intact;
(5) double-deck bonding film is put into complex pocket making apparatus and toast, make adhesives cure into solid by liquid, obtain complex film;
(6) complex film is made packaging bag by Bag Making Machine through the heat-sealing of 4Pa high pressure-temperature.
Good effect of the present invention is: 1, the inner membrance of the direct heat packs pack of this microwave is high temperature resistant, the resistance to expansion of adventitia, the stickness of adhesives is strong, inner membrance stay line, boxing out allows packaging bag fully in conjunction with the feature of microwave-oven-heating, guarantee microwave heating and vapor heated perfect effect, vapor discharge is scientific and reasonable; 2, the quick-frozen food of 300 of this packaging bags grams of left and right is put into micro-wave oven, the steam producing on the basis of microwave heating can retain continuous heating stable discharge, the micro-wave oven of 1000 watts of power only needs 3-4 minute, remove out the loaded down with trivial details operation of bag simultaneously from, and the danger factor of thoroughly having avoided sack explosion.
