A Review of The Recyclable Packaging Design in Flexible Packaging Industry
Abstract
Currently, many reasons such as the rapid progress of technology, increasing population, industrialization efforts and the increase in the rate of unconscious plastic consumption negatively affect the world and the environment. Food packaging wastes constitute large proportion of today's plastic waste since they have multilayer composite structure such as PET, metalized PET (PETMET), Aluminum, PE, BOPP etc. Because of the different structures in composite packaging, recycling cannot be performed. In this study, conversion of composite packaging structure to both polyolefin and mono polymeric component were carried out in order to make the packaging structures suitable for recycling. There were several difficulties while developing mono material structures. However, these difficulties were overcame by using improved materials and changing production process parameters.
