Plastic Suppliers, Inc. (PSI) has announced the introduction of EarthFirst UL, an ultra-thin, bio-based sealant web designed to lower the cost of sealant films used in flexible packaging, while offering all the environmental advantages of PSI’s EarthFirst family of bio-based plastics.
EarthFirst UL is made from lactic acid found in several renewable organic feedstocks, like tapioca roots, sugar beets, sugar cane and corn.
Brand owners and flexible packaging converters benefit from improved efficiencies, lower energy usage, reductions in product-to-package ratios and lower cost per MSI versus traditional LDPE sealant films. Through commercial testing and trials, the company has been able to quantify significant improvements to the overall supply chain efficiency with EarthFirst UL in lower freight costs, reducing costly roll changeovers, requiring less storage and reducing the material volume entering the solid waste stream. At the same time, this can be accomplished with a more environmentally friendly film.
“Our customers have been demanding innovation in packaging that does more with less,” says PSI president/CEO George Thomas. “Our ability to provide an ultra-thin gauge, high-performance sealant film meets that need. The whole supply chain is more efficient, more cost-effective and with a product that is sustainable and compostable. It is a win-win for the brand owners and flexible packaging converters. EarthFirst UL really is a game-changer.”
EarthFirst UL is suitable for food packaging applications using single-serve pillow pouches, coffee frac-packs, gusseted standup pouches, frozen foods and multi-wall bags. When compared to LLDPE, EarthFirst UL forms superior seals at lower seal initiation temperatures. Its naturally high dyne levels make it ideal as a laminate to PET, metPET, PP, nylon and paper substrates. UL has an excellent aroma barrier, is grease resistant and is available in 9, 12, and 15-micron gauges.
