A film comprises first, second, and third layers. The first layer comprises vinylidene chloride polymer. The second layer comprises a dispersion of tie polymer and nanoparticles. The third layer comprises thermoplastic polymer. The second layer is between and directly adhered to both the first and third layers. The film provides an enhanced interlayer bond strength between the layers at the elevated temperatures associated with cook-in, retort, and/or pasteurization thermoprocessing. |
