PURPOSE: Provided is a method for producing a high density resin film for milk pack, which can enhance working stability and reliability of product, and can maintain a form of the pack, and thus satisfy both workability and appetite of consumer. CONSTITUTION: The method comprising the steps of (i) mixing high density polyethylenes to form a mixture, (ii) melting the mixture at 145-170 deg.C and feeding the molten product to cylinder, (iii) blower-extruding the product though dies at 145-165 deg.C(with injecting a predetermined amount of air by air hose), and air-cooling the product at velocity of 350¬+10 rpm to obtain a semi-product of 500 m 1R/L, wherein product size information of 102 m/m x 150 micron x 14.5 kg is input in the dies, is characterized in that in the step(i), a blending ratio of the resin is Samsung(120A) 30-45%: Honam(7000F) 30-45%: Honam(4000B) 40-10%.
