Flexible Liquid Packaging Pouches Reduce Costs and Waste
DuPont resins for liquid packaging preserve beverage freshness, protect liquid contents, and minimize storage and waste.
With a broad portfolio of packaging resins and technologies, proven application development expertise and technical support, DuPont helps brand owners and converters create innovative liquid packaging pouches. We focus on finding the best solution for every application, and pouch uses range from cooking oil to children’s juices to non-food products.
Nucrel® and Bynel® for Cooking Oil Pouches
Cooking oils packaged in sealed nylon pouches cut liquid packaging equipment costs while ensuring a hygienic, unadulterated product for consumers (in some parts of the world, used oils are rebottled and sold as new). To minimize leakers, these tough pouches rely on a heat-seal layer of Nucrel® acid copolymer resin bound to the nylon barrier layer by Bynel® coextrudable adhesive resin.
Surlyn®for Flexible Consumer Packaging
Today it’s feasible to package liquid products such as household cleaners in flexible pouches, thanks to Surlyn® resin. In addition to cutting storage and shipping costs, these rugged, leak-proof, flexible packages provide dramatic graphic capabilities compared to conventional rigid containers. And Surlyn® meets tough performance requirements with the best hot tack, seal-through contamination, and stiffness of any high-performance sealant.
