Flexible packaging plastic known as OPP and BOPP (oriented and biaxially oriented polypropylene) is a very shiny plastic, often perfectly clear or brightly coloured, and not stretchy at all. It is commonly used for packaging and presentation e.g. the outer packaging on cigarette boxes, greetings cards, pasta bags, confectionery and pastries.

OPP is a very common single-use plastic found all over the world, and among the least recycled.

We are looking for simple processes, appropriate technologies and applications suitable for low-income countries. Can you find a low-tech way to turn used OPP into something useful?
