Abstract
A polymerizable pre-adhesive composition includes packaging material and a packaged pre-adhesive reactive mixture sealed within the packaging material. The packaging material includes: a semicrystalline polylactic acid (PLA); a polyvinyl acetate (PVAc); and a plasticizer; wherein the PLA/PVAc-containing packaging material has a single Tg of less than 25° C. and a normalized Haze value of less than 10% per 25 microns.
