Description
Technical field
The invention belongs to plant plastics manufacture field, and in particular to a kind of quick-freezing fresh-keeping food bag and its manufacture craft.
Background technology
With the continuous improvement of people's living standards, market, which is stated, occurs in that miscellaneous food, occurs shape shape and color therewith
The food pack of color.For some food, particularly ready-to-eat food, consumer is after sealed packaging bag is opened if not
Disposable it can finish, the food in it will be difficult to again be at closed state, especially for being easy to absorb or lose
The food for going moisture rotten, if not keeping sealing state before in next time, it will the quick product of food is lost original attribute,
Such as biscuit moisture absorption softening, bread dehydration is dried, milk powder moisture absorption caking etc..
The content of the invention
A kind of quick-freezing fresh-keeping food bag, is made up of following component by weight：
60 parts of polypropylene, 60 parts of polyvinyl alcohol, 2 parts of epoxy aliphatic acid methyl ester, 2 parts of lauryl glucosyl, laruyl alcohol
2 parts of sodium sulphate, 2 parts of Cocoamidopropyl betaine, 30 parts of phenolic resin, 2 parts of potassium sorbate, 1 part of lime stone, plant extracts
2 parts, 0.1 part of glyceryl monostearate.
The lime stone passes through modification：Lime stone is first placed into the deionized water that mass fraction is 0.12%,
Soaking temperature is 60-70 DEG C, after soaking 3-4 hours, is cooled to 35-40 DEG C, and it is 250W ultrasounds for 35kHZ, power to use frequency
Processing 15-20 minutes, is cooled to room temperature, filters, drying.
A kind of manufacture craft of quick-freezing fresh-keeping food bag is, in accordance with the following steps：
(1) polypropylene, polyvinyl alcohol and phenolic resin are heated to molten condition, add sldium lauryl sulfate and at
The lime stone of reason, is stirred 30 minutes with 1000r/min speed, then pressurizeed；
(2) plant extracts is carried out being heated to 50-60 DEG C, then adds potassium sorbate and cocamidopropyl propyl amide beet
Alkali, is stirred 15-20 minutes；
(3) raw material for obtaining step (2) is added in step (1), after being well mixed, then adds stearic acid list glycerine
Ester, after stirring 20 minutes, is added in double screw extruder and it is extruded；
(4) after twin-screw squeezes extruder extruding, the raw material after extrusion is subjected to blowfilm shaping with single-screw extrusion machine,
Charge temperature is 70 DEG C during blown film, and compression plasticization temperature is 110-120 DEG C；
(5) cooled down after being molded, that is, obtain the quick-freezing fresh-keeping food bag.
The beneficial effects of the present invention are：Food pack light weight of the present invention, elasticity is good, and tear resistance is good, and
Also there is excellent environmental stress crack resistance, low-temperature impact resistance and resistance to warping energy, it is not easy to stick between packaging bag and food
Even, pick and place conveniently, the fresh keeping time of fresh-keeping foodstuff packaging bag of the present invention is 3 to 5 months, shelf lives 12-14 months, brittleness is protected
Two first quarter moons or so are held, people's demand fresh-keeping for a long time is disclosure satisfy that.
