Austria-based polyolefins manufacturer Borealis and Menshen, a leading specialist for plastic closures and packaging systems, have collaborated on a series of 10 packaging closures based on Borcycle, an evolving recycling technology that transforms polyolefin-based waste streams into value-adding versatile solutions.
Borcycle is used to manufacture a range of compounds made of recycled polyolefins (rPO), which are ideal for sophisticated rigid packaging applications. This evolving technology unites Borealis recycling and compounding expertise with its own. These packaging solutions are predominantly made for use in laundry and home care and also include 2K closures.
With over 50 years’ experience, Menshen is a recognized and trusted leader in closure design, offering a wide range of standard and specialty assembled caps, weldspouts, and hot drink capsules on the market today. The company is currently present with production facilities in 14 countries worldwide, offering unified quality standards and a customer experience supported by Centres of R&D Excellence in Europe and China. Menshen has the ambition to produce 25% of its closure solutions from recycled materials by 2025.
Menshen employs a rigorous process to ensure that the quality of the post-consumer recycled (PCR) material selected for closure is in perfect alignment with its required functionality. In the course of the collaboration, Borealis and Menshen determined that Borcycle UG522MO, a polypropylene (PP) compound made of 50% PCR content, would be the suitable choice for the new closures, as it offers:
- Potential reduction of CO2 emissions by up to 15% when compared to the use of comparable virgin PP in similarly demanding packaging solutions
- Reliable and consistently high quality, making it ideal for rigid packaging applications
- A ready-made, drop-in solution with processability rivaling virgin polyolefins
- End-of-life recyclability in existing PCR streams.
“A core pillar of the mind-set is that value chain collaboration is essential to making plastics more circular,” says Meta Cigon, Borealis Marketing Manager Consumer Products. “Teaming up with Menshen to deliver high-quality closures made of 50% recycled PCR is proof positive that innovation and teamwork can move the industry closer to a circular economy. We are helping build a better tomorrow with each step by reinventing for more sustainable living.”
“The functionality of a closure may be affected by natural variations in PCR materials. By leveraging our respective areas of expertise, Menshen and Borealis can determine which ratios of recyclate and virgin material are appropriate for which applications,” explains Ulrich Fleischer, Menshen head of Sustainability. “We are pleased to collaborate with Borealis in fulfilling growing demand among our own customers as well as retailers and end consumers for a broader spectrum of sustainable, yet high-quality packaging options.”
