There is provided a polymer film which includes a base film layer having an absolute weight average molecular weight of 50,000 to 1,000,000 and an adhesive layer, and a method for manufacturing the polymer film. This film for a tire inner liner can endow an excellent gas barrier property even to tires having a relatively thin thickness so that weight of the tire can be reduced and fuel efficiency of automobiles can be improved. Further, the present film facilitates molding in a tire manufacturing process, and exhibits excellent adhesion force to a carcass layer while having excellent mechanical properties such as high durability and fatigue resistance together with excellent moldability.

Polymer films

Disclosed is a film for a tire inner liner including a base film layer having an absolute weight-average molecular weight of 50,000 to 1,000,000, and an adhesive layer, and a method for manufacturing the film for a tire inner liner. The film for a tire inner liner may exhibit excellent gas barrier properties while having a thin thickness and lighter weight, and thus improves fuel efficiency, allows easier construction during its preparation, has excellent mechanical properties including high durability and fatigue resistance, and provides excellent adhesive strength to a tire carcass layer.
