Abstract
A laminate for blister pack applications is comprised of a paperboard substrate having a first printable surface and a second surface onto which there is applied a polymeric coating suitable for adhering the plastic blister to the paperboard. The polymeric coating comprises a coextrusion consisting of a polyolefin material such as low density polyethylene (LDPE) which gives good adhesion to the paperboard surface and an adhesive material such as an ethylene-methyl acrylate copolymer (EMA) which gives good adhesion to the plastic blister.
