PSI introduces new bio-based sealant web
Plastic Suppliers, Inc. had introduced EarthFirst UL, an ultra-thin, bio-based sealant web used for flexible packaging applications. EarthFirst UL is made from lactic acid found in several renewable organic feedstocks like tapioca roots, sugar beets, sugar cane and corn, according to the company.
Both brand owners and flexible packaging converters will benefit from improved efficiencies, lower energy usage, reductions in product-to-package ratios and lower cost per MSI versus traditional LDPE sealant films, Plastic Suppliers, Inc. (PSI) reports. Through commercial testing and trials, the company has been able to quantify improvements to the overall supply chain efficiency with EarthFirst UL in lower freight costs, reducing costly roll change-overs, 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.
EarthFirst UL is ideal for food packaging applications using single-serve pillow pouches, coffee frac-packs, gusseted stand-up pouches, frozen foods and multi-wall bags. When compared to LLDPE, EarthFirst UL forms superior seals at lower seal initiation temperatures, according to PSI. It’s naturally high dyne levels make it ideal as a laminate to PET, metPET, PP, Nylon and paper substrates, the company reports. UL has a great aroma barrier, grease-resistant attributes and is available in 9, 12 and 15 micron gauges (.36mil, .48mil, and .6mil).
