Abstract
A labeled package includes a polymeric package, a filmic facestock material as a label on the polymeric package, and a pressure sensitive adhesive adhering the filmic facestock material to the polymeric package. The pressure sensitive adhesive composition includes a monomer mixture, which includes at least one monomer that is free radical polymerizable and whose homopolymer has a glass transition temperature of less than or equal to 10° C.; at least one mono-olefinically unsaturated monomer having aldehyde or ketone functionality; and at least one polyhydrazide crosslinker having hydrazine functionality.
Claims23
A labeled package, comprising:
- a polymeric package;
- a filmic facestock material as a label on the polymeric package;
- and
- a pressure sensitive adhesive adhering the filmic facestock material to the polymeric package, the pressure sensitive adhesive composition comprising a monomer mixture, wherein the monomer mixture comprises (a) at least one monomer that is free radical polymerizable and whose homopolymer has a glass transition temperature of less than or equal to 10° C., (b) at least one mono-olefinically unsaturated monomer having aldehyde or ketone functionality, and (c) at least one polyhydrazide crosslinker having hydrazine functionality;
- wherein the pressure sensitive adhesive composition exhibits a peel adhesion value of between about 0.4 lbs/in (70 N/m) and about 4 lbs/in (700 N/m);
- and
- wherein a percent film remaining on the polymeric packaging after a sink-float testing is from 0% to about 8%.
