Abstract

A multilayer barrier film comprising at least one first resin layer and at least two second resin layer, both outermost layers being the second resin layers, wherein the first resin layer comprising PVOH having Tm 170~220 degrees Celsius and the second resin layer comprising PLA or PET having Tm 205 degrees Celsius or less, can enhance gas-barrier property by adjusting a thickness of the PVOH layer and exhibits good biodegradability since it employs environmentally friendly resins.
