The present invention is a laminated film having at least one layer formed of a gas barrier resin composition satisfying the following equations (1) and (2), and having an average shrinkage ratio of 45% or more in the longitudinal direction after being immersed in an oil bath at 120 ° C. for 10 seconds. Provided are shrinkable films characterized by:n n n n n n n n n n n n n n n n n (In formula 1, OTR and T im are oxygen transmittance (cc / m 2 · day · atm) and gas at 23 ° C. and 0% relative humidity, respectively, of the 1 μm thick portion of the film formed of the gas barrier resin composition. Is the melting point of the barrier resin composition, wherein T 1 is the haze (%) of the 30 μm thick film of the gas barrier resin composition left for 48 hours at 23 ° C. and 48% relative humidity and T 2 is 40 ° C. And haze (%) of a 30 μm thick film of gas barrier resin composition left for 24 hours at 90% relative humidity.n n n TECHNICAL FIELD This invention relates especially to the shrinkable film which considers the environment which has favorable oxygen barrier property, processability, transparency, and especially ductility, and is used suitably for packaging of foods. |
