Thermoplastic polymeric laminates are prepared which have one layer of filled styrene polymer composition, and at least one layer of a dissimilar polymer selected from polyolefins such as polyethylene, polypropylene and polybutene, and nitrile group containing barrier polymers. The filled styrene polymer composition contains from 5 to 50 parts by weight filler, and is the product of mixing a styrene polymer masterbatch of impact polystyrene, filler, rubber and oil with polystyrene. The laminates can be used for thermoforming thin walled articles such as cups, plates, trays and containers. |
