Dow, BOBST, Hosokawa Alpine and ELBA to jointly present recyclable barrier packaging

Thursday 17. October 2019 - Thanks to the joint development with machine manufacturer BOBST, extrusion converter Hosokawa Alpine and packaging producer ELBA, Dow (NYSE: DOW) will present a selection of polyethylene-based(PE) pouches that allow for the production of medium-to-high barrier packaging with machine direction oriented (MDO) films designed for recyclability.

Prototypes will be on display at K 2019, the world’s No.1 trade fair for plastics and rubber, at the stands of the companies: Dow (stand K48, hall 8a), BOBST (stand A39, Hall 4), Hosokawa Alpine (stand D06, Hall 16) and ELBA (stand D36, Hall 3).
One of the biggest challenges in designing PE-based packaging for recyclability is to incorporate barrier functionalities that are today carried out by different materials in multi- material structures,” said Jaroslaw Jelinek, EMEA marketing manager at Dow Packaging & Specialty Plastics. “Thanks to our Pack Studios expertise fueled by strong industry collaborations we have developed our next generation of high-performance resins to help enabling the production of PE-based mono-material packaging solutions that are designed for recyclability.”
In combining state-of-the-art MDO conversion machinery with Dow’s innovative PE-based polymers, similar production efficiency to existing multi-material packaging structures has been achieved. Dow products enabling this solution include: ELITETM resins for remarkable stiffness, thermal resistance, optics and a wide enough orientation window which is important for the MDO process; NUCRELTM copolymers to create a suitable surface for the coating and metallization; INNATETM precision resins for balanced toughness and stiffness as well as enhanced dimensional performance; and AFFINITYTM sealants to provide a low seal temperature and good operating window on the packaging line.
“We must work to find solutions that are efficient, innovative and that can lead to a circular economy,” said Romain Cazenave, EMEA marketing director at Dow Packaging & Specialty Plastics. “The array of prototypes we are presenting at K 2019, such as the one developed together with BOBST, Hosokawa Alpine and ELBA, clearly demonstrates that mono-material PE-based packaging is the future, contributing to move the industry towards recyclable packaging.”
