What is Elmer’s glue made from?
Now Elmer’s Glue-All is an aqueous emulsion of Polyvinyl acetate, Polyvinyl alcohol, and Propylene glycol distributed in plastic squeeze type bottles with twist-open dispenser lids. It is widely used in homes, businesses, and schools and effectively bonds most materials, such as wood, paper, and fabric.
