Film, package and method of producing the film and package

[Abstract] The present invention describes an optional flexible and/or polymeric packaging film (eg BOPP) having at least one tear line (5) and at least one tab (7), tab (7) ) has a free end, an end connected to the membrane and a free side connecting the two ends, the tongue (7) being positioned so that the axis of the at least one tear line (5) passes through the tongue (7) Both ends, characterized in that: (a) at least one free side of the tongue (7) tapers outwards from the connecting end and the tear line (5); and (b) at least one angled jet tower (θ) ) is an acute angle greater than approximately 5[deg.], in which the shooting tower ([theta]) is defined as an angle facing the free end of the tongue (7), which is measured between the following: (i) one by the tongue ( The axis defined by the average direction of one of the sides of 7), which is averaged over the last quarter of the maximum length of the tabs starting from the connection end; and (ii) one along the membrane The axis of the tear is defined by the average direction of the tear line. Also described is a method of preparing such a film and a package article (such as a cigarette box) externally wrapped with such a film.
[Sovereign Items] 1. A packaging film having at least one tear line and at least one tongue, the tongue having a free end, an end attached to the film and a free side connecting the two ends, The tongue is positioned so that the axis of the at least one tear line passes through both ends of the tongue and is characterized in that (a) at least one free side of the tongue gradually tapers outward from the connecting end and the tear line; and b) At least one angled mast (θ) is an acute angle greater than approximately 5°, the mast (θ) is defined as the angle of the free end of a subtend tab, which is measured between (i) an axis defined by the average direction of one side of the tongue, the average of which is averaged over the last quarter of the maximum length of a tongue from the attachment end; and (ii.) ) An axis defined by the average direction of the tear line along the membrane.
