<p><P>PROBLEM TO BE SOLVED: To provide a film for packaging, capable of being torn off along an unsealing tape in a linear state and steadily, even if the unsealing tape is pulled in the diagonal direction, with respect to a packaging biaxially oriented film, such that unsealing tapes are laminated in the width direction of the film. <P>SOLUTION: The film for packaging is of a biaxially oriented polypropylene resin, on which the unsealing tapes K are bonded for use in the direction parallel to the width direction of the film. The tensile elongation of the film in the longitudinal direction is 170% or lower, while the unsealing tapes K are bonded, for configuration, in the direction of the width of this biaxially oriented laminated polypropylene resin film, thus to be made into a packaging film for use. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
