Paper-based packaging solutions were prolific at Pack Expo Las Vegas, including for flexible packaging. ProAmpac launched its patent-pending ProActive Recyclable RP-1000 High Barrier (HB) paper-based technology for food packaging.
An extension to its existing ProActive Recyclable RP-1000 series, RP 1000 HB offers “excellent oxygen, moisture barrier, and grease resistance” according to ProAmpac. As such, suitable applications include dry food products such as dehydrated fruit, confectionery, and flavoured oatmeal.
In a media briefing at PackExpo, Nathan Klettlinger, global marketing director at ProAmpac, told PKN that the material is pre-qualified by How2Recycle as kerbside recyclable in paper streams.
It’s also compatible with existing converting equipment, as Klettlinger noted: “RP-1000HB seamlessly integrates with existing equipment, simplifying the transition process and minimising costs compared to less efficient sustainable alternatives.”
ProAmpac maintains that unlike conventional paper solutions that offer inadequate grease resistance and subsequent packaging vulnerabilities, RP-1000HB delivers superior grease resistance with excellent seal performance on horizontal and vertical form/fill/sealing lines. The company says its distinctive characteristics pave the way for integrating recyclable fibre-based packaging into numerous applications
Positioned as a sustainable alternative to traditional multi-material laminates, RP-1000HB is available in versatile formats, including rollstock and pre-made three-sided seal pouches.
Natural Kraft and bleached paper options are available, offering "exceptional printability" that enables easy brand promotion and customisation.
“In rigorous tests simulating up to 85 per cent relative humidity conditions, RP-1000HB preserves its barrier properties, assuring the longevity of products susceptible to spoilage due to environmental moisture,” Klettlinger said.
