THE STUDY OF THE DESTRUCTIVE PROPERTIES OF WOOD-FILLED COMPOSITES FOR THE PRODUCTION OF BIODEGRADABLE PACKAGING MATERIALS
Abstract
Today it is difficult to imagine the area of human life, where polymeric materials are not used. However, the increasing consumption of polymers for packaging, as well as other household disposable products creates a problem of plastic waste and a threat to the en-vironment. The chemical stability of polymers makes it possible to withstand the effects of physicochemical (solar radiation, heat, humidity, oxygen of the air) and biological (microorganisms) natural factors for many decades without noticeable destruction. In this connection, the development, production and use of new types of biodegradable composite materials for the packaging industry, which can biodegrade to environmen-tally friendly components under appropriate conditions, is relevant. This article discusses the possibility of using a biodegradable composite material, based on polylactide and filler, made of thermally modified wood flour, for packaging. It has been established that polylactide packaging with the addition of 60% thermo-modified wood filler would provide a high rate of biodegradation of the used packaging, thereby reducing the environmental stress on the environment. At the same time, the resulting composite will have acceptable physicomechanical and special characteristics intended for use as a package.
