Abstract (en)
[origin: EP1785357A1] The invention concerns a method of manufacturing an easy-to-open shrink sleeve wrapped package comprising wrapping up one or more products in a shrink thermoplastic film and submitting the obtained sleeve to a heat shrinking step to give a tight package, wherein the package comprises a tear strip defined by perforations to facilitate opening of the package, said method being characterized in that a) the tear strip is defined by a close sequence of pairs of mutually diverging weakness segments, having the same or substantially the same shape and size, and diverging in the same direction, and b) said sequence of pairs of mutually diverging weakness segments is created by perforating across the film width before the wrapping step. The invention also concerns a unit for perforating a film.
