Abstract

The invention provides a high-barrier degradable packaging material and a preparation method thereof. The preparation method comprises the following steps that 1, 2,6-naphthalic acid glycol ester, polypropylene carbonate, polycaprolactone, petroleum resin, an ethylene-ethenol copolymer, sodium-based montmorillonite, nano titanium dioxide, chitin and hydroxypropyl methyl cellulose are mixed and are stirred with a high-speed mixer; 2, erucyl amide, n-butyl stearate, castor oil and glycerol are added, and stirring continues by using the high-speed mixer; 3, the mixture is charged into a double-screw extruder for extrusion and granulation; 4, blow-molding is performed with a blow-molding machine after cooling. The high-barrier degradable packaging material has good mechanical properties, excellent barrier performance, meanwhile has good degradation performance and is green and environmentally friendly.
