moisture barrier

In building a future beyond fossils, UPM Specialty Papers provides the packaging industry with innovative and renewable solutions from sustainably managed forests. Known for its high expertise in technically demanding papers and cutting-edge solutions, UPM Specialty Papers adds heat sealable products to UPM’s wide packaging product portfolio. This ground-breaking feature allows for a streamlined conversion process and an accelerated time-to-market. Made from renewable fibres, UPM Confidio and UPM Confidio Pro are repulpable and designed to be recycled in regular fibre recycling streams.

A high-density polyethylene (HDPE) resin that offers significantly improved moisture barrier for multilayer flexible packaging and enables development of more recyclable polyethylene (PE) films has been introduced.

From Nova Chemicals,  the new resin — named Surpass HPs267-AB HDPE — is designed for blown-film applications. Nova reports that it delivers up to 20% an increase in water-vapor transmission performance in multilayer coextruded films vs. Nova’s best-in-class Surpass HPs167-AB resin.

The company is awaiting a patent on the packaging technology, which is compliant with European and US Food and Drug Administration standards and available in stand-up and three-side seal configurations.
