Polypropylene

One aspect of Greiner Packaging’s sustainability strategy is reducing its material usage, a goal it has been pursuing for some time now. The company aims to produce packaging that exhibits the same functionality and improved recyclability when compared with previous solutions, in order to cut back on plastic from virgin materials as well as carbon emissions.

Greiner Packaging achieved a material saving of 20% for the new Greek yogurt cup, having reduced the solution’s weight by making adjustments to technical conditions in production.

PureCycle harnesses a patented process that transforms plastic waste into a like-new recycled plastic that can continually be reused and potentially stay out of landfills and oceans. The PureCycle process is unique because it separates color, odor and contaminants from plastic waste feedstock to transform it into ultrapure recycled polypropylene with lower greenhouse emissions than traditional resin.

The Refill a Box scheme is the first of its kind to be trialled by a UK supermarket. Each ‘rentable’ box will replace Morrisons large salad box and is made from fully recyclable polypropylene. The boxes are designed to be used 400 times to prevent disposable plastic containers from being used. 

L’Oréal and packaging maker Texen have joined forces to develop a new generation of caps made from 100% recycled polypropylene (rPP) for the beauty giant’s Biotherm brand.

The move forms part of L’Oréal’s drive to reduce the environmental footprint of its packaging.

According to Texen, the caps can be adapted to different shapes of jar for skin care formulas under the blue beauty player, including Cera Repair and Blue Therapy.

This ever-expanding ecological crisis caught the attention of 33-year-old Montrealer Mishel Wong. She has just launched an app-based reusable takeout packaging service in the city, the “Bo option.” In collaboration with 16 restaurants in the Plateau/Mile End districts, customers now have the option to choose reusable packaging in the form of what she calls “Bo containers” when ordering takeout.

The two ICP resins are the first in Socar’s portfolio to incorporate Milliken Chemical’s Hyperform HPN performance additive for PP. The two firms have been working together on developing the materials for the past year.

According to Socar, the new grades are ideal for use in thin-wall injection moulded (TWIM) packaging applications such as caps, closures and opaque containers, as well as in various housewares, sporting goods and toys.

• Mondi and Dutch cheese packaging company Hazeleger have developed a mono-material solution for packaging Westland Kaas’ Maaslander cheese slices
• The light-weight solution, which is also fully recyclable, replaces a heavier multi-layer plastic solution
• Mondi’s mono-material meets the high oxygen and moisture barrier properties required to protect and keep cheese slices fresh during transport and while on the shelf

Most sliced cheese in the Netherlands is still packaged in mixed material film, which is difficult to recycle.

The Coalition will work to cement polypropylene’s status as a standard curbside recycling material through projects that enhance collection, sorting and processing in recycling facilities to increase the value and supply of recycled polypropylene (rPP), and reduce the need for virgin plastic used in packaging. According to a statement from Keurig Dr Pepper, this sponsorship supports the company’s broader efforts to reduce its plastic footprint.
