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.
Claims24
A labeled plastic container suitable for containing a pharmaceutical or food grade product comprising:
- a walled structure comprising a polyolefin material defining an interior space suitable for containing a liquid or solid food product or pharmaceutical product;
- and
- a laminate label bound to an outer surface of said walled structure, wherein said laminate label comprises;
- a substantially clear or translucent protective polymeric film bound to a face stock by a radiation-cured 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 adsorbes radiation-curable monomers and inhibits radiation-curing of the adsorbed radiation-curable monomers, and combinations thereof, and wherein said laminate lable has been formed by ultraviolet light curing for said low-migration, radiation-curable adhesive composition through said substantially clear polymeric film.
