Comparison of the properties of the original and applied LDPE foils in returned bottles


A constant increase in the production of plastic products is a major cause of general environmental pollution. The past decade recognized how significant recycling plastic waste and the development of biodegradable materials is. This paper takes a new look at reducing the amount of plastic waste in the environment. Plastic bottles are “dressed” in a special PE (polyethylene) foil before filling. After the content is consumed, the foil is removed of the bottle. Such foil can be used for transporting other products more than once. The work focuses on the investigation of the changes in properties of the light density polyethylene (LDPE) foils caused by forming during their application to the bottle. It was decided that the optimal method for this investigation was to compare the mechanical and rheological properties PE foils before and after their application to the bottle.
