Disclosed are hot-melt, curl-free methods, structures, and compositions, which in flexible packaging applications, reduce mineral-oil, hydrocarbon migration into packaged food. One embodiment provides an optionally oriented base film having a first side and a second side that is a transparent or opaque film. Further, the composition comprises, consists essentially of, or consists of a water-based primer applied to the first side. Further still, the composition includes a barrier layer to mineral-oil migration, wherein the barrier layer is located between the adhesive-receptive layer and the polymeric substrate, and wherein the barrier layer consists essentially of: (i) polymers of polyvinyl alcohol, ethylene vinyl alcohol, polyester, polyamide, or combinations thereof; and (ii) optionally additives. The barrier layer provides a barrier to mineral-oil migration of 0.1 &#x3bc;g/day*dmor less at 40&#xb0; C. for 40 days, and the curl-resistant composition does not curl when heated for at least one hour at 60&#xb0; C.

Mitigation of mineral oil migration in pressure-sensitive labels and films

This disclosure provides compositions, films, labels, structures and methods that may include a substrate having a first side and a second side, wherein the first side comprises a skin layer comprising at least 50 wt. % of high-density polyethylene. Further, the compositions may include a coating on the skin layer, wherein the coating comprises a topcoat and a primer, wherein the topcoat consists of: (i) at least 50 wt. % high-density polyethylene and one or more polyethylene polymers in water; (ii) wax, silicone or combination thereof; and (iii) optionally additives, whereupon imaging the composition by a thermal print head at a temperature of 300&#xb0; C. or less results in no or negligible solvent-penetrability beneath the skin layer.
