Abstract

Biaxially oriented film and metal laminate composite thereof useful for manufacturing food containers with good resistance to blushing during steam sterilization, comprising a blend of PBT and PET and also incorporating color pigment comprising polar functional groups. The films possess improve resistance to trans-esterification during melt processing, resulting in enhanced crystallinity levels present in the laminated film which leads to little or no blush discoloration during steam sterilization.
