    Patent number: 6815048
    Abstract: Polymeric films including a layer of propylene polymer resin having microvoids therein, the microvoids having been formed by stretching a web containing the beta-form of polypropylene, have shown low static cling when being unwound from rolls in labelling operations and also during destacking of pre-formed labels. The invention provides labels formed from such films.

  • Polymeric films
    Patent number: 6787222
    Abstract: Biaxially oriented polymeric films having a core layer of a voided propylene homopolymer with a density of not more than 0.70 g/cm3, and at least one substantially non-voided layer on each surface of the core layer, the ratio of the combined thicknesses of the non-voided layers on the respective surfaces of the core layer being from 2:1 to 1:1. Films in accordance with the present invention have low curl, particularly after having been printed.
