New high-clarity polypropylenes for thin-walled packaging / Focus on injection moulded containers
Increasing demand for very high clarity packaging articles has led Saudi Arabia’s National Petrochemical Industrial Company
(Natpet, Jeddah; www.natpetpp.com
) to upgrade its range of polypropylene random copolymers. The two new grades "Teldene R25MLT" and "Teldene R40MLT", both containing Milliken Chemicals
(Spartanburg, South Carolina / USA; www.millikenchemical.com
) "Millad NX 8000" clarifying agent, are mainly aimed at markets for thin-walled injection moulded food and non-food containers, especially in Europe, Turkey, the Middle East and Asia.
The two new grades have melt flow rates of 25 and 40 g/10 min. Although their mechanical properties are quite similar, Teldene R40MLT has a higher flow and is thus better suited for complex products and high-speed machines.
Natpet said the grades also allow converters to save energy and costs, since both Teldene R25MLT and R40MLT can be processed at lower temperatures and cycle times than similar products.
