1.8 parts of sodium, 1.5 parts of lignin, 1.6 parts of plasticizer.
Further, the fluoropolymer resin is polyvinyl resin.
Further, the chitin modified polyvinyl alcohol the preparation method comprises the following steps:
After polyvinyl alcohol is mixed with deionized water by 1:10 mass ratio, poly-vinyl alcohol solution is obtained, then adds its quality
2.5% acetic acid after mixing evenly, then adds the chitosan of poly-vinyl alcohol solution quality 5.8%, with 300r/min revolving speed stirring 2
Hour, then carry out rotary evaporation it is dry to get.
Further, the nanometer calcium carbonate granularity is 100nm.
Further, the plasticizer is tributyl citrate.
Further, the isopropyl myristate modified nano graphite alkene the preparation method comprises the following steps:
Nano-graphene is evenly spread in acetone, is configured to the nano-graphene dispersion liquid that mass fraction is 10%, then again
Isopropyl myristate is added in nano-graphene dispersion liquid, after mixing evenly, is heated to 125 DEG C, is turned with 500r/min
Speed stirring 2 hours, then filtered, cleaned using dehydrated alcohol, drying to constant weight to get；The myristic acid is different
Propyl ester additive amount is the 1.2% of nano-graphene dispersion liquid quality.
It is good that the present invention has the advantage that a kind of antibacterial food freshness protection package of the present invention not only has compared with prior art
Tensile strength, while also there is good anti-bacterial refreshing effect, the bacteriostasis rate of Escherichia coli, staphylococcus aureus is up to
99%, significant effect is extended using the fresh keeping time of freshness protection package packaging fruit of the present invention compared to existing preservative film fresh keeping time
20 days or so.
