TC Transcontinental developed and commercialized a new stand up pouch for Harney & Sons loose leaf tea using a layer of EVOH to provide the required barrier properties and the Dow Chemical Company’s RETAIN compatibilizer to enable recyclability through the established polyethylene film recycling stream. The pouch also provides the needed durability, heat seal strength, easy open laser score, resealable zipper, and high quality graphical characteristics.
Why it’s important:
Multi-material flexible packaging is a rapidly growing segment of the packaging market that tends to have pronounced advantages in terms of resource efficiency and emissions intensity mirrored by a pronounced disadvantage in terms of recyclability. There has been significant activity around simplifying structures to become mono-layers of polyethylene in order to enable recyclability, but that shift is usually accompanied by a loss of the barrier properties provided by the non-polyethylene layers.
TC Transcontinental and their supply chain partners are the first to bring to market an example of multi-material flexible packaging that retains its advantages in barrier properties, resource efficiency, emissions intensity, and can be recycled through the network of store drop-off collection receptacles that are widely available to consumers, significantly broadening the sustainability story of an important type of packaging.
