Preferably, the preparation method of the domestic freezer meat storage freshness protection package, comprising the following steps:
(1) 45-55min is mixed in polyethylene, precipitated calcium carbonate, epoxidized soybean oil, chitosan, Sodium Polyacrylate, Mixing speed is 400-600r/min, and polyethylene terephthalate, waterproofing agent, plasticizer is added and continuess to mix stirring 30- 35min, mixing speed 350-450r/min, then direct blowfilm shaping, blown film temperature are controlled at 190 DEG C -210 DEG C, are obtained Plastic outer layer；
(2) tung oil, rosin, castor oil, thickener, film forming agent are mixed evenly, mixing speed 350-450r/ Min obtains mixed liquor；
(3) mixed liquor is evenly coated in plastic outer layer one end, is then heated using far infrared, heating temperature is 70-90 DEG C, heating time 30-40min, 55-65 DEG C of hot wind 10-15min is passed through after heating immediately, it is then naturally cold But to room temperature, packaging material is obtained；
(4) take 2/3 packaging material to carry out bag making with Bag Making Machine, obtain polybag, take 1/3 packaging material, its not Mixed liquor is uniformly smeared in the one end for applying mixed liquor, is heating and curing, the mode that is heating and curing is identical as step (3), is cooled to room It is cut after warm, obtains plastic sheet, more than two plastic sheets are bonded on polybag, plastic sheet only has one side and polybag Bonding, two plastic sheets store freshness protection package at a distance of 12-15cm to get the domestic freezer meat.
Preferably, in the step (4), polybag is rectangular, length 30-35cm, width 15-19cm, the modeling The width of tablet and the equivalent width of polybag, the length of the plastic sheet are 10-13cm.
Compared with prior art, the beneficial effects of the present invention are:
(1) mixed liquor in the present invention is made of tung oil, rosin, castor oil, thickener, film forming agent, is coated in outside plastics Layer protecting film can be formed on layer, even if the moisture on meat surface forms one layer of thin ice, will not be bonded together with freshness protection package.
(2) present invention is easy to use, and a freshness protection package can store muti-piece meat, and application method is as follows, hand be protruded into fresh-keeping In bag, catches piece of meat to overturn sack, replace sack inside and outside, the one side for being stained with plastic sheet enters in freshness protection package, will lean on The plastic sheet of nearly piece of meat covers above piece of meat, then places second piece of meat again above the plastic sheet, and so on. Since plastic sheet two sides all will not be Nian Jie with chilled meat, so meat is taken when instant edible, meanwhile, freshness protection package can be made to reach maximum Utilization rate reduces the waste of freshness protection package.
