The invention relates to a flexible polymeric film for enveloping a container comprising: a tear path; and a tear tab extending from the outer surface of the film; wherein the tear path comprises at least one fault line arranged to facilitate tearing of the film in one direction when the tear tab is pulled in a direction generally perpendicular to the container; wherein the at least one fault line comprises an embossed pattern being positioned to enhance the sound generated by the tearing of the at least one fault line.

Films, packaging and methods for making them

There is described a biaxially oriented polyolefin single or multi-layer film which comprises at least one core layer comprising a propylenic polymer component and either an ethylenic polymer component (preferably 0.2% to 8% by weight of core layer) or a styrenic polymer component (preferably 0.2% to 25% by weight of core layer). The films have a dynamic loss modulus (E&#x2033;), at 3 Hz and 25&#xb0; C., of 28 to 136 MPa (TD) and/or 73 to 135 MPa (MD) as well as a dynamic storage modulus (E'), at 3 Hz and 25&#xb0; C., of 630 to 2800 MPa (TD) and/or 1300 to 3000 MPa (MD). These films are suitable for use as a label facestock with improved conformability for example to provide improved labels for squeezable containers.

There is described a flexible oriented film () which acts a replacement for tear film, the film () having at least one tear susceptible line () or pattern thereon (preferably weaker than the surrounding film), the film tearing substantially therealong when tearing is initiated therealong, characterised in that the line () or pattern has substantially the same thickness normal to the film surface (gauge) as the rest of the film; and/or the film material therealong is substantially differently (preferably more) oriented (in extent and/or direction) to that in the rest of the film. The means for forming the line () or pattern is preferably a laser (e.g. infra-red COlaser) set at a sufficiently low power not to ablate material therealong but at a sufficiently high power to reorient the film therealong. A method of preparing such films () and packaging () (such as cigarette packs) overwrapped with such films () are also described.
