New plastic packaging innovations have produced a flexible polymer that stretches to capacity and returns to its original shape. The product was co-developed by BAM Materials Research and Testing and Bayer Material Science. It is call thermoplastic polyurethane (TPU). When heated to a certain temperature, the “switching temperature”, the plastic returns to its originally intended shape. The material is durable yet free from plasticizers and antihydrolysis agents making it acceptable for food packaging. This new development protect the product’s quick read code until the poly returns to its original shape. Therefore, the products identity is protected and extremely difficult to counterfeit.
