Abstract: A single-dose sealed pack with break opening having a first sheet of semi-rigid plastic material, and a second sheet of flexible plastic material, to define a sealed chamber for containing a dose of a product, the first sheet including a bearing layer and a barrier layer, wherein the barrier layer is arranged towards the outside of the chamber with respect to the bearing layer. The single-dose pack also having a first cut on the inner face of the first sheet to guide the breakage of the first sheet form an opening to allow product to exit, the first cut having a section defining the bending axis of the pack, the barrier layer being of the isotropic and not perforated type and having a lower elongation at break than the maximum elongation applicable to it by the only thickness of the bearing layer following the bending of the pack itself.

Abstract: The single-dose sealed pack (1) with break opening includes a first sheet (2) made of semi-rigid plastic material, a second sheet (3) made of flexible plastic material associated with the first sheet (2) to define a sealed containment chamber for containing at least a dose of a product, wherein on a face (2a) of the first sheet are defined at least a pair of first cuts (4) spaced out from each other and on the opposite face (2b) is defined at least a second cut (5) arranged in correspondence to the area (6) between the first cuts (4), so as to determine a substantially sudden breakage of the first sheet itself in correspondence to the area (6) between the first cuts (4) and such to substantially involve the entire extension of the second cut (5).
