    摘要: Provided is a squeezable oriented polypropylene adhesive film that can be formed into a label comprising at least one core layer sandwiched between at least two skin layers, the layers comprising: a core layer comprising a polypropylene and within the range of from 20 wt % to 50 wt %, by weight of the materials in the core layer, of a propylene-α-olefin elastomer having within the range of from 5 wt % to 25 wt % α-olefin derived units, by weight of the elastomer; a printable skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the printable skin layer, or an α-olefin copolymer comprising at least 30 wt % ethylene; and an adhesive-accepting skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the adhesive-accepting skin layer, of a polypropylene.
