Abstract
A laminate comprises a first substrate including a first layer of a blend of a polyolefin and an antifogging agent, and a bonding layer of polyolefin, preferably an ethylene unsaturated ester copolymer or low density polyethylene; a second substrate bonded to the bonding layer of the first substrate and comprising polyester or nylon; and a conventional adhesive between the first and second substrates; the bonding layer pre-treated by corona discharge before wind-up, and again treated by corona discharge before lamination. The laminates of the present invention exhibit much improved bond strength compared with conventional laminates.
