Flexible packaging has been increasing in volume replacing more traditional rigid formats such as glass jars and steel cans.  While this flexibility provides benefits such as lighter weight and easier opening, it can provide challenges in secondary packaging and transportation.  In addition, many flexible packages are made from films which utilize multiple layers of different materials.  Often these materials are dissimilar and form incompatible melts upon reprocessing.  This renders these films and the packages made from them unsuitable for mechanical recycling.  New technologies that allow for either the recycling of multilayer flexible films or energy recovery will be discussed as will the importance of transportation packaging and safety in sustainability.
