Abstract:

The paper introduced the basic properties of several typical commercially available biodegradable thermoplastics, including polylactic acid, poly(butylene adipate⁃co⁃terephthalate), polypropylene carbonate, and polybutylene succinate and reviewed the research progress in their modification. Several forming technologies for preparing biodegradable plastic packaging films were introduced in detail, including blowing film, casting, calendering, and biaxial stretching methods. The recent application status of biodegradable plastic films as green packaging materials was described.

Key words: biodegradable plastic, packaging film, functional modification, thermoplastic processing, product application
