  • Publication number: 20170369689
    Abstract: A substantially planar sheet having two opposable surfaces, the sheet having at least one layer formed from a first optionally polymeric material and a second optionally polymeric material, the second material having a lower elasticity modulus (1% Secant) than the first material, incorporation of the second material producing a sheet having a tensile strength and/or elasticity modulus of about 90% or less of that of a sheet without such material when measured in any direction parallel to the sheet surface. Such conformable sheets and films are particularly useful for labelling and graphic art applications.
    Type: Application

  • Patent number: 7927712
    Abstract: 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?), at 3 Hz and 25° 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° 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.
