Flexible packaging is an important part of our modern world. Mainly made of plastic films, it helps ensure products reach consumers safe and fresh, preserving nutrients, taste, and quality. Being very light and thin, flexible packaging materials reduce the impact of transportation, reduce waste of the goods they protect and usually use far less material than alternative packaging options.
Minimising product and packaging waste with low weight and volume is key in a circular economy. But an equally important objective is to design flexible packaging so that it will be correctly disposed of, collected, and efficiently sorted into suitable material fractions for recycling. These sorted materials must be recyclable into ‘new’ ones that can be used in market applications, displacing virgin material.
