The cap features sugarcane-derived high-density polyethylene. And Tetra Pak's new Tetra Brik Aseptic 1000 Edge with Bio-based Lightcap 30 offering is the first aseptic carton to receive the highest class of certification from Belgium-based Vinçotte for its use of renewable materials, Barcas says. Made with 80 percent renewable content, the package boasts up to a 17 percent lower carbon footprint than a standard package, according to an independent lifecycle analysis conducted by the IVL Swedish Environmental Research Institute. For its part, SIG Combibloc, headquartered in Neuhausen am Rheinfall, Switzerland (with North American offices in Philadelphia and Toronto), recently introduced the combibloc RS composite structure for its aseptic carton packs. The structure improves system stability during processing, while contributing to even better environmental performance, the company says.
