A package (10, 20, 30, 40, 50) which can be torn open by a user, comprising a polymer film material having a preferential tearing direction and defining a cavity for a product, wherein the polymer film material incorporates a bias (16, 24, 35, 56) facilitating tearing along a tear line oriented in a direction other than its preferential tearing direction and a tear initiation location (18, 26, 37, 41, 58) which facilitates tearing of the polymer film material in its preferential tearing direction to open the package, the tear line being adjacent to a tear initiation location. The polymer film material having a preferential tearing direction provides resistance against a child tearing open the package. |
