Abstract: Nowadays food packing waste are seriously polluting environment gradually. That developing edible food packing is considered as an effective method to relieve the contradiction between food packing waste and environment protection. High-amylose corn starch, compared with other film-forming medium, has good film-forming quality and its waste is renewable and friendly to environment. It costs lower comparatively, hence there is a promising future for high-amylose corn starch. This research studied the film-forming quality under the condition of high temperature and high press by using high-amylose corn starch as material.

Key words: high-amylose corn starch, high temperature and high press, film-forming quality
