Abstract:
Co-processable multi-layer laminates having a high T layer and at least one low T layer with layers having properties of high strength, lo- or no-haze, and transparency after processing into various multi-layer forms are useful for packaging and container applications. The multi-layer laminate has at least one low T layer of a first thermoplastic polyester having at least one crystallization rate inhibitor. The total amount of crystallization rate inhibitor is effective to prevent substantial haze in the low T layer upon heating. In most applications, the total amount of crystallization rate inhibitor also does not substantially inhibit strain-induced crystallization of the at least one low T layer when the laminate is stretched during processing. The multi-layer laminates of the invention have improved properties such as reduced shrinkage and/or high barrier properties, with a very small amount of high T material used to impart these improved properties to the laminate.
