PROBLEM TO BE SOLVED: To provide a shrinkable barrier film which shows proper hot water shrinkage as a shrinkable film and shows excellent oxygen barrier as a barrier film. SOLUTION: A shrinkable barrier film is composed of 60 to 85 mass % of an aliphatic polyamide and 40 to 15 mass % of a xylylene-based polyamide and shows shrinkage of 15 to 40 % when it is treated in hot water at 80 deg.C for 30 min and an oxygen transmission degree of not more than 150 ml/m2.day.Mpa. The shrinkable barrier film is manufactured under a specific heat treating condition. |
