Abstract
A film facestock useful for making labels for use on deformable substrates, which labels are die-cuttable and dispensable, the film facestock including a layer of a polymer blend which includes an ethylenic material, a styrenic material, and a compatibilizing material.
Claims27
A deformable label suitable for attachment to a selected substrate, comprising:
- a printable film facestock together with a usefully dispersed adhesive on one side of the facestock for affixing said film facestock to the substrate by means of the intervening adhesive, said film facestock including a layer of a polymer blend which comprises:
- a first material selected from the group consisting of high impact polystyrene, rubber-modified polystyrene, general purpose polystyrene, and mixtures thereof;
- a second material selected from the group consisting of linear low, ultra low density, low density and medium density polyethylene, copolymers of ethylene and propylene, of ethylene and acrylate monomers, of ethylene and vinyl acetate, and of ethylene and acrylic acid, and mixtures thereof;
- and
- a compatibilizing material;
- said adhesive being selected from the group of materials characterized by the ability to form a bond with said film facestock such that the strength of the film-adhesive interface and the substrate-adhesive interface and the cohesive strength of the adhesive itself are both greater than the forces required for deformation and recovery of the film itself;
- and
- a release-coated liner material releasably bonded to said adhesive.

A deformable label on a deformable substrate, which label demonstrates improved resistance to damage from cracking, tearing, creasing, wrinkling or shrinking due to deformation of the deformable substrate to which the label is joined, comprising:
- a printable film facestock together with an adhesive on one side of the facestock and positioned between the facestock and the substrate for affixing said film facestock to the substrate, said film facestock including a layer of a polymer blend which comprises:
- a first material selected from the group consisting of high impact polystyrene, rubber-modified polystyrene, general purpose polystyrene, and mixtures thereof;
- a second material selected from the group consisting of linear low, ultra low density, low density and medium density polyethylenes, copolymers of ethylene and propylene, of ethylene and acrylate monomers, of ethylene and vinyl acetate, and of ethylene and acrylic acid, and mixture thereof;
- and
- a compatibilizing material;
- said adhesive being selected from the group of material characterized by the ability to form a bond with said composite film such that the strength of the film-adhesive interface and the substrate-adhesive interface and the cohesive strength of the adhesive itself are both greater than the forces required for deformation and recovery of the film itself.
