An elastic film having an elastic film layer based on styrene block copolymer, such that the elastic film layer is formed from a first styrene block copolymer and a second styrene block copolymer without the addition of polystyrene. The first styrene block copolymer has a styrene portion of less than 25% by weight and the second styrene block copolymer has a styrene portion of more than 26% by weight. A ratio of the first styrene block copolymer to the second styrene block copolymer is between 6:1 and 2:3.
