Melinex® 3380 and Melinex® CORE1 are one-side heat sealable, opaque white polyester films which are ideal in specialty laminated card applications. These films can be heat sealed to themselves and other polyesters, as well as a variety of substrates. The two films are identical except that CORE1 is supplied sheeted with the heat seal surface modified to prevent air entrapment during lamination. CORE1 is required where two layers of CORE1 are laminated to each other as part of the card construction. These two films are currently available at thicknesses of 600 gauge and 1210 gauge.Information provided by DuPont. |
