摘要：
A product packaging that exhibits good linear tear behavior. The product packaging being a multi-layer film having an inner layer made from a blend of ethylene copolymer and polypropylene copolymer. The inner layer of the multi-layer film being a substantial proportion of the thickness of the multi-layer film. The multi-layer film having linear tear behavior even when a force is applied at an angle offset from the tear direction.
