An injection molding composition is capable of being injection-molded easily at a temperature lower than that of a conventional composition, and an injection molded product has improved strength. More specifically, an injection molding composition containing HPMCAS has a hydroxypropoxy molar substitution of 0.40 or more. In addition, a method produces an injection molded product including a step of injecting into a mold the injection molding composition at from 50 to 250 C.

Provided is the use of a film of a cellulose ester as a barrier against moisture and oil. The cellulose ester has free hydroxyl groups and ester substituents. The ester substituents are each individually selected from C1 to C6 alkyl ester groups. The free hydroxyl groups are present in an amount in the range 15% to 40 mol %. The film is useful as a barrier layer for food packaging. Also provided is a composition comprising the cellulose ester and a further film-forming material, a packaging material comprising a film of the composition, and a method for manufacturing the packaging material.
