The Influence of the Composition of Polyethylene, Starch, and Monoglyceride Biodegradable Compositions on Their Physicomechanical Properties and Structure

The methods for the preparation of biodegradable hybrid composite films based on polyethylene, thermoplastic starch (corn, pea, and rice), and distilled onoglycerides (instead of sorbitol), with a mass ratio of components of 40 : 60—60 : 40, respectively, are described, and their physicomechanical properties are studied. The properties and structural features of the composite films are studied with rheology, optical microscopy, and differential scanning calorimetry. The monoglycerides proposed as a plasticizer for the “thermoplastic starch : polyethylene” compositions are advantageous.
