Abstract:
1. A protective roll wrap for wrapping a paper roll having a first roll end and a second roll end opposite to the first roll end, the protective roll wrap comprising: a wrapper having a first edge strip for forming a first crimp on the first roll end, a second edge strip for forming a second crimp on the second roll end, and a peripheral strip extending between the first edge strip and the second edge strip, the wrapper having a first paper layer with a width W 1 and a second paper layer with a width W 3 , the width W 1 being wider than the width W 3 , a heat sensitive adhesive layer extending between the first and the second paper layers and having a width W 2 wider than the width W 3 , thereby providing at least one exposed adhesive strip extending at least partially along at least one of the first and the second edge strips, wherein crimping one of the first and the second edge strips having the at least one exposed adhesive strip creates overlapped sections with interior folds having sections of the exposed adhesive strip facing each other in adhesive-to-adhesive contact and activating the heat sensitive adhesive layer seals the interior folds preventing liquid infiltration between the overlapped sections.
