According to Tata Steel, the key to the success of its collaboration is a new product called Protact which, it is claimed, offers a unique internal polypropylene (PP) layer which enabled the groundbreaking direct seal concept. This concept, it is claimed, eliminates the need for a traditional can ring and delivers a 24% steel weight reduction overall.
By using this coating, Grupo Calvo was also able to use its innovative Vuelca Fácil® or ‘Easy Flip’ aluminium film lid which allows the can to be opened easily and safely.
