<p>A water-retardant film lamina is disclosed. The printable prepared layer (referring to printing papers like label stock) is laminated on top with a film of biaxial oriented polypropylene (BOPP) to retard the encroachment of water; or a printable prepared layer is applied on top of the film of biaxial oriented polypropylene (BOPP). Further, the biaxial oriented polypropylene (BOPP) can be laminated at both upper and lower sides with a layer of fastening agent which is further applied on top with a removable layer. The film of biaxial oriented polypropylene (BOPP) has pre-cut tracks or openings of different shapes such as circles or rectangles at a proper interval so that the lamina can be easily torn apart at the pre-cut tracks or openings to provide an easy-tearing as well as water-retardant film lamina. <IMAGE></p> |
