Single-dose sealed pack with break opening

Single-dose sealed pack (1) with break opening comprising:

• a first sheet (2) of semi-rigid plastic material;
• a second sheet (3) of flexible plastic material associated with said first sheet (2), to define a sealed containment chamber (4) for containing at least a dose of a product;
• said first sheet (2) comprising at least a bearing layer (6) and at least a barrier layer (7), each of them having its own thickness, wherein said barrier layer (7) is arranged towards the outside of said chamber (4) with respect to said bearing layer (6),
• wherein it comprises at least a first cut (5a) defined at least on the inner face of said first sheet (2) to guide the breakage of the first sheet itself so as to determine the formation of an opening to allow the product to come out, said first cut (5a) comprising an individual rectilinear section defining the bending axis of the pack, and wherein said barrier layer (7) is of the isotropic and not perforated type and has a lower elongation at break than the maximum elongation applicable to it by the only thickness of said bearing layer (6) following the bending of the pack itself.
