Dow, Bobst, Hosokawa Alpine and Elba
Joint presentation of recyclable barrier packaging at K 2019

15.10.2019 Thanks to the joint development with machine manufacturer Bobst, extrusion converter Hosokawa Alpine and packaging producer Elba, 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 leading 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).

Incorporating barrier functionalities

“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  multimaterial structures,” said Jaroslaw Jelinek, EMEA marketing manager at Dow Packaging & Specialty Plastics. “Thanks to our Pack Studios expertise fuelled 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: ELITE resins for remarkable stiffness, thermal resistance, optics and a wide enough orientation window which is important for the MDO process; NUCREL copolymers to create a suitable surface for the coating and metallization; INNATE precision resins for balanced toughness and stiffness as well as enhanced dimensional performance; and AFFINITY sealants to provide a low seal temperature and good operating window on the packaging line.

Towards a circular economy

“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.”
