Abstract: There is described a sheet packaging material (M) for producing a sealed package (1) of a pourable food product; the packaging material (M) comprises one base layer (11) for imparting stiffness, a number of lamination layers (12) covering both sides of the base layer (11), and a removable portion (10, 10', 10'', 10''', 10'''', 10''''') which, in use, can be detached partly from the rest of the packaging material (M) along at least one arc-shaped cutting line (20, 20''''') and folded at a folding zone (21, 81) extending between the opposite ends of the cutting line (20, 20''''') so as to free a pour opening (9) by which to pour the food product from the package (1); the removable portion (10, 10', 10", 10'", 10"", 10'"") comprises a central area (25) made of whole packaging material and which, in use, in any case, remains attached to the rest of the packaging material (M) through a permanent bridge (26) defined by the folding zone (21, 81), and a peripheral area (27, 27', 27", 27'", 27"", 27'"") for cutting interaction, extending around part of the central area (25), containing the cutting line (20, 20'"") and including at least one pre-laminated opening (30, 30', 30", 30'", 30a"", 30b"", 30c"", 30'""), which is formed by a through slot (31, 31', 31", 31'", 31a"", 31b"", 31c"", 31'"") provided at least in the base layer (1) and covered by one or more of the lamination layers (12).
