Abstract
Provided is a laminate label adapted for use on plastic containers suitable for containing a pharmaceutical or food grade product. The laminate label includes a substantially clear or translucent protective polymeric layer bound to a face stock by a radiation-cured adhesive composition formulated from a low-migration, radiation-curable adhesive composition containing at least 50% of one or more radiation-curable, carboxylic acid functional monomers.
Claims26
A laminate label suitable for use on polyolefin containers suitable for containing a pharmaceutical or food grade product, said laminate label comprising:
- a substantially clear or translucent protective polymeric layer bound to a face stock by a radiation-cured adhesive composition formulated from a low-migration, radiation-curable adhesive composition comprising at least 50% of one or more radiation-curable, carboxylic acid functional monomers, wherein said face stock comprises at least one selected from the group consisting of paper, synthetic material that absorbes radiation-curable monomers and inhibiting radiation-curing of the adsorbed radiation-curable monomers, and combinations thereof, and wherein said laminate label has been formed by ultraviolet light curing of said low-migration, radiation-curable adhesive composition through said substantially clear polymeric film.
