Greiner Packaging values diversity in terms of material use and is focusing on a broad portfolio of packaging materials which includes PET, PP, PS, and also bio-circular materials. When it comes to using recycled materials, most of the industry is currently only working with r-PET, while Greiner Packaging is already in a position to favour either r-PET or recycled polypropylene (r-PP), and can produce the majority of its products using either material.
Greiner Packaging UK & Ireland recently invested over £3,700,000 in a new PET decontamination and extrusion line to enable the use of more recycled materials in its market leading cup and tub ranges, as well as continuing innovation with more sustainable materials.
Until now, PET has faced the major challenge of heat resistance and has not been used for dairy packaging, as the dairy industry applies high temperature steam sterilization (HTS) to disinfect cups before filling. Greiner Packaging has now successfully developed cups made from PET and r-PET that are heat resistant up to temperatures of 120˚C. This not only allows their use for dairy products, but also for hot drinks and dry soup or noodle ready-meals that are filled up with boiling water before consumption.
In another exciting development, Greiner Packaging has successfully produced a food cup made of premium polyolefins obtained exclusively from second-generation waste and residue streams. The new BornewablesTM line of products is manufactured by Borealis and offers the same characteristics as virgin polyolefin materials while boasting a substantially reduced carbon footprint. A life cycle analysis has shown that using BornewablesTM substantially reduces a product’s carbon footprint by at least 2.7 kg CO2eq for every kilogram of polymer, representing a saving of up to 120% in comparison to fossil-based PP.
“Visitors to stand C33 at lunch! will see a wide variety of sustainable foodservice packaging solutions and will be able talk to our experts about our plastic tax-exempt packaging options,” says Rachel Sheldon. “Through innovation, Greiner Packaging is working with every viable material to deliver efficient and eye-catching packaging solutions for the food industry. Recycled plastic is the future, and that’s why we love sustainable plastic.”
