FIELD: chemistry.
SUBSTANCE: invention relates to an extruded article based on polymer of propylene polymer, intended for use in packaging, in articles for food preparation, household purpose, as well as in products for heat treatment of food products or medical products. Product is made from propylene polymer obtained by polymerisation in presence of Ziegler-Natta catalyst, containing in amount of 0 to 1.0 wt. % ethylene and/or C4-C10 α-olefin comonomer.
EFFECT: proposed extruded products have improved optical properties, such as turbidity or relative turbidity, and good balance between optical and thermomechanical properties.
