Abstract
This invention relates to labels. In one embodiment, the labels comprise (A) a polymer film comprising a styrenic polymer, said film having an upper surface and a lower surface, and an MVTR of from about 15 to about 150 g/m2/day, and (B) a water-based adhesive in contact with the lower surface of the film. These labels can be bonded to substrates of glass, plastic or metal using the water based adhesive.

A label comprising:
- (A) a polymer film comprising a styrenic polymer, said film having an upper surface and a lower surface, and an MVTR of from about 15 to about 150 g/m2/day, and
- (B) a water-based adhesive in contact with the lower surface of the film.
A label comprising:
- (A) an oriented film comprising a styrenic polymer, said film having an upper surface and a lower surface, and an MVTR of from about 15 to about 90 g/m2/day, and
- (B) a water-based adhesive in contact with the lower surface of the film.
A process for applying a label to a substrate which comprises:
- (A) providing a substrate and a polymer film comprising a styrenic polymer, said film having an upper surface and a lower surface, and an MVTR of from about 15 to about 150 g/m2/day,
- (B) applying a water-based adhesive to the lower surface of the film to form a label,
- (C) applying the label to the substrate with the adhesive of the label in contact with the substrate, and
- (D) drying the water-based adhesive thereby providing an adhesive label on the substrate.
