PP T 31 S Technical Datasheet
Product Description:
T 31 SE is a polypropylene homopolymer particularly suited for clear and pigmented thermoforming applications. T 31 SE offers high stiffness, excellent processability, good contact clarity and high gloss. T 31 SE is increasingly used for the extrusion of sheet for thermoforming. In thermoforming, polypropylene offers some distinct advantages over conventional materials like PVC and PS. Polypropylene gives extensive food contact credentials, a good toughness-stiffness balance and excellent high temperature and chemical resistance. Moreover, polypropylene offers easy recycling and is environmentally sound.
Applications:
The main applications are vending cups, blister packs, packaging for dairy products, trays for biscuits, chocolates and fruits. T 31 SE is also used for coextruded multilayer sheet with high barrier properties to produce retortable containers.
