The launch of a ‘next generation’ transparent polypropylene grade, Borpact SH950MO, will offer “a step-up in performance and processing sustainability” to the frozen food packaging sector, according to plastics and chemicals company Borealis.
The new Borpact SH950MO is said to feature good drop impact properties in low temperatures, with enhanced performance compared to its predecessor Borpact SG930MO, thanks to a higher flow (melt flow rate of 40) and better processability with improved stiffness (1050 MPa).
Based on the company’s Borealis Nucleation Technology (BNT), the improved properties and better processing efficiency of the new material will bring benefits and cost savings throughout the packaging value chain, the company says.
Borealis business unit moulding vice president Rainer Höfling says: “We have invested in creating a next generation grade with improved processability and end product performance that takes the lead in supporting the sustainability and differentiation requirements of the thin wall consumer packaging market.”
Developed primarily for packaging of deep freeze products such as ice cream, frozen desserts and other frozen food items, Borpact SH950MO is also suitable for applications in broader consumer packaging and housewares, where the combination of good impact performance and transparency is a top priority.
Other advantages of the new Borpact SH950MO are described as:
- Opportunity to downguage material use, enabling thinner walls and more complex designs without compromising product properties
- Higher flowability – enables converters to use lower processing temperatures, supporting energy and cycle time savings
- Reduction of injection pressure, as observed during trials
- Better demoulding properties – improved formulation and higher stiffness leads to improved overall efficiency
- Brand owners – visually appealing packages can offer a clear view of the contents, without fear of damage or brittle breakages
- High gloss and very low stress whitening ideal for special closure designs
Borealis will be showcasing Borpact SH950MO at the Thin Wall Packaging Conference from 3-5 December 2012 at the Maritim Hotel in Cologne, Germany.
