At least one of the outer and inner edge portions comprises at least one region provided with a resealable adhesive (12). The sheet has at least one folding axis (309, 309′) dividing said sheet into a first and second regions region. The sheet is folded about said at least one folding axis with said first and second regions in an overlapping configuration, thereby providing a packaging unit. Overlapping outer edge portions of the sheet layers are at least partly adhesive-free and are at least partially connected to each other by a mechanical interaction providing a sealing strength of 0.2 to 1.5 N. A method for forming the packaging unit is provided.
