The present invention provides a package (10) comprising an outer film layer (32) and at least one inner film layer (34,36), the inner and outer film layers being mutually laminated. The package also comprises a pair of mutually spaced lines of weakness (20) in at least the outer film layer, and means (22) for initiating tearing of the film layers. The lines of weakness and tear initiation means are disposed such that activation of the tear initiation means causes controlled tearing of all the film layers along the lines of weakness. The package is particularly suitable for block products such as chocolate bars.
