Beverage cartons have already been on the market for over 100 years. The milk carton, originally entirely made of paperboard and thus 100 percent bio-based, was patented in 1915.
A century later, beverage cartons are the most widely used packaging for fresh liquid fluids such as milk, yoghurt and other dairy produce.
Packaging in cartons became so popular with beverage suppliers because of lower (transport) costs, and with consumers for their convenience: cartons are lighter and safer to use than glass. Whether single-use beverage cartons are also more environmentally friendly than re-suable glass bottles is highly debated.
