“PLA film, which is created from corn rather than petrochemicals, as a packaging-grade plastic, is a notable example,” he says. “Adhesives are now being defined that will allow these materials to flow smoothly into labeling applications. Benefits unique to individual end-use applications derive from the use of lower surface energy materials, but this also represents one of the more difficult substrates on which to achieve an adhesive bond.”
