The results of this joint effort, designed to create a healthier future, have been on display at the K 2022 trade fair. Milliken displayed high-density polyethylene (HDPE) tubes produced using Huhtamaki laminates optimized with Milliken Ultra- Guard™ Solutions technology. With the market’s keen focus on recycling and circularity, it is more vital than ever to find technologies that can eliminate the typical metalized (usually aluminum) lay- ers while maintaining the necessary bar- rier properties, especially against water vapor and oxygen transmission needed in personal-care applications. By improving the barrier properties of HDPE film by up to 50 percent, Ultra- Guard Solutions contribute to sustainabi- lity by enabling more mono-material construction of popular products such as stand-up flexible pouches and tubes and making them ultimately more recyclable. These improved barrier properties also allow for downgauging of the polyethy- lene (PE) film, resulting in a lighter-weight end product and a reduction in the amount of resin needed to achieve the desired result. Huhtamaki’s work on this project fits in perfectly with its blueloop™ initiative for sustainable, flexible packaging. Huhta- maki blueloop is a product portfolio ai- ming to make flexible packaging circular by introducing a range of recyclable solu- tions with mono-material structures using polypropylene (PP), PE and paper. The blueloop program contains recyclable and sustainable laminate solutions, with dedi- cated criteria, to ensure the resulting mono-HDPE-laminate is fully recyclable and approved by RecyClass. “The tube resulting from this joint deve- lopment work is opaque with a silver shine, making it ideal for beauty product applications,” said Dr. Detlev Schulz, Se- nior Manager – Sustainability and Busi- ness Development for Huhtamaki’s Global Tube Laminates business. “White would work as well, offering outstanding mois- ture barrier and improved oxygen trans- mission for all who don’t need a shiny silver option." The most likely end uses will be in 40 to 200 ml tubes. (图片 / Photo ©2022 Milliken & Company)
