Borealis launches a new solution for transparent, thin wall packaging

Borealis A/S : 08 July, 2006  (New Product)
Borealis has launched a new solution for transparent, thin wall packaging which meets the demands for improved product visibility, lighter weight but stronger packaging, better stackability and integrated features for convenience and tamper-proof solutions.
Borealis has launched a new solution for transparent, thin wall packaging which meets the demands for improved product visibility, lighter weight but stronger packaging, better stackability and integrated features for convenience and tamper-proof solutions.

The RJ470MO solution offers the well-established properties of polypropylene random copolymers, such as stiffness, impact performance and low density and a new route to greater productivity. The solution delivers clear benefits to retailers and consumers in packaging for dairy, confectionary and convenience food as well as for electronics and cosmetics.

RJ470MO is able to satisfy all of these requirements and do so faster than ever before by pushing back the boundaries of design and thickness, while at the same time increasing efficiency and saving cost. With a high fluidity Melt Flow Rate of 70, this new grade provides optimum transparency, quick demoulding and high output for injection moulded parts with very thin walls, long flow lengths and complex geometries.

Significant reduction of waste
'By switching from MFR 45 to MFR 70 we have been able to meet the market's demands,' says Sergio Tontarelli of the plastic housewares manufacturer Tontarelli Group. 'We have experienced no modification to transparency and mechanical characteristics, while at the same time being able to reduce cycle time in comparison to the MFR 45 random. There has also been a significant reduction of waste.'

Typically, the very fast crystallisation of RJ470MO allows moulders to reduce cycle times by as much as 10% when compared with standard PP randoms with MFR 45. This gives a significant advantage in food and appliance packaging and houseware applications.

This solution is a replacement of standard random copolymers and offers the possibility to downgauge and lower part weight, as well as increase output.
