Beschreibung
Zusammenfassung:	The invention discloses an anti-puncture dairy product packaging film and a production method thereof.The production method comprises the following steps that a base film is subjected to ultrasonic treatment and then subjected to plasma treatment, in the ion treatment process, the electrode distance is 3-4 cm, the oxygen flow rate is 0.5-1.5 mL/min, the vacuum degree is 12-15 Pa, the discharge time is 10-20 s, the discharge voltage is 100-200 V, and a pretreated base film is obtained; the preparation method comprises the following steps: adding nano cellulose into tetrahydrofuran, uniformly dispersing, adding a styrene-butadiene-styrene block copolymer, dendritic polyamide-amine and nano graphene oxide, and uniformly stirring to obtain a spraying solution; in an ethanol steam atmosphere, spraying the spraying liquid on the outer side of the pretreated base membrane, obtaining a protective layer after tetrahydrofuran is completely volatilized, and drying at room temperature; and emptying air, carrying out coro
