Researchers at VTT, Technical Research Centre in Finland have found a way to reinforce biodegradable plastic bags with natural fibres. This results in plastic bags that are still biodegradable, but with increased durability, paving the way for more applications.
Using flax fibres, the researchers are able to tailor the properties of the biocomposite according to the use. They have achieved desired strengths by using appropriate combinations of bioplastic and flax fibres.
One advantage of the biocomposite biodegradable plastic bags is that they can be manufactured using the same production lines as conventional plastic bags. The manufacturing process for the biocomposite plastic bags was further refined by studying the resistance of the biocomposite to heat moisture and UV radiation.
