Package comprising a wrapping with a reclosable withdrawal opening, and relative packing method and machine

14) A packing method for producing a package;

• the packing method comprising the steps of:
• forming a sheet (24) of multilayer packing material by superimposing and gluing, with non-dry, re-stick adhesive, an inner layer (25) having a withdrawal opening (5), and an outer layer (26) having a sealing panel (6) for closing the withdrawal opening (5);
• and
• folding the sheet (24) of multilayer packing material about a group (4) of articles to form a sealed wrapping (3), which encloses the group (4) of articles and has the withdrawal opening (5) closed by the sealing panel (6);
• the packing method being characterized by comprising the further step of interposing, between the inner layer (25) and the outer layer (26), an intermediate layer (30), which is located outwards of the withdrawal opening (5) and superimposed on the sealing panel (6) to form a grip tab (29) with no re-stick adhesive on the side facing the inner layer (25).

18) A packing machine for producing a package;

• the packing machine (34) comprising:
• a forming station (35) for forming a sheet (24) of multilayer packing material by superimposing and gluing, with non-dry, re-stick adhesive, an inner layer (25) having a withdrawal opening (5), and an outer layer (26) having a sealing panel (6) for closing the withdrawal opening (5);
• and
• a packing station (36) for folding the sheet (24) of multilayer packing material about a group (4) of articles to form a sealed wrapping (3), which encloses the group (4) of articles and has the withdrawal opening (5) closed by the sealing panel (6);
• the packing machine (34) being characterized in that the forming station (35) interposes, between the inner layer (25) and the outer layer (26), an intermediate layer (30), which is located outwards of the withdrawal opening (5) and superimposed on the sealing panel (6) to form a grip tab (29) with no re-stick adhesive on the side facing the inner layer (25).

20) A packing machine for producing a package;

• the packing machine (34) comprising:
• a forming station (35) for forming a sheet (24) of packing material having a withdrawal opening (5) closed by a reclosable sealing panel (6) with a grip tab (29);
• and
• a packing station (36) for folding the sheet (24) of packing material about a group (4) of articles to form a sealed wrapping (3) enclosing the group (4) of articles and having a withdrawal opening (5) closed by the sealing panel (6);
• the packing machine (34) being characterized by comprising a creasing device (44) for creasing the grip tab (29) along a fold line (45) separating the grip tab (29) from the rest of the sealing panel (6).
