Study of structure and properties of biodegradable composite films based on thermoplastic starch

Abstract

The increasing use of plastic products is causing pollution of nature with micro plastics, plastic waste and harmful substances. In this work, the possibility of obtaining thermoplastic starch was studied; its structure and properties were investigated. The biodegradable compositions based on polyethylene-starch and polyethylene-thermoplastic starches were obtained, in which starch was used as a filler in the polyethylene matrix. Comparative studies of composites properties, such as optical, physic-mechanical, rheological and biodegradability were carried out. The polyethylene-thermoplastic starch-based composite films with biodegradable properties can be used as packaging materials instead of packaging polyethylene bags.
