Netherlands-based Yparex BV says it is the first supplier in the packaging industry to develop and commercialise a bio-based adhesive tie layer for multilayer packaging films, using 95% annually renewable resources.
Yparex BV – a leading supplier of extrudable tie layer resins for a variety of high-tech applications, including multilayer barrier packaging film, medical film, multilayer pipe, architectural wall cladding, and wire & cable – says its new Yparex Renew tie layer resin is fully recyclable, yet “meets the same performance specifications as non-renewable petroleum-based polymer of the same family”.
“It offers packaging manufacturers the opportunity to make their products more sustainable because plant precursors sequestered greenhouse gases during their life cycle,” the company says. “However, it also helps protect the packaging industry’s supply chain from price spikes of materials closely tied to the cost of oil and natural gas.”
The new extrusion grade – an extension of the company’s existing Yparex brand adhesive tie-layer resin for multilayer barrier-packaging producers – is said to be suitable for blown or cast multilayer film structures that use common barrier resins like polyamide (PA) and ethylene vinyl alcohol (EVOH).
The new polymer is described as “the perfect drop-in solution for packaging manufacturers looking to lower their carbon footprint”, and the first of what the company hopes will become a growing family of bio-based ‘green’ tie layer grades.
“There’s a lot of disagreement about how best to make the packaging industry more sustainable,” says Yparex BV general manager Wouter van den Berg. “Yparex management decided that the best way we could contribute was by formulating the greenest tie resin we could make.
“We are shipping our first lot of green Yparex Renew resin to an innovative film producer this month for evaluation,” he adds. “We hope the packaging industry responds favourably to this sustainable product offering.”
