Beverage Packaging that Pours On the Performance
DuPont resins for beverage packaging improve the performance of glass, plastic, and juice box containers.
As the global leader in specialty polymer materials, DuPont collaborates with packaging converters to create innovative beverage packaging solutions. In fact, DuPont launched the polymer packaging revolution with the invention of the PET soda bottle, and we’ve been introducing breakthrough packaging concepts ever since.
High-performance resins used for beverage packaging include DuPont™ Surlyn® ionomer resin, DuPont™ Nucrel® ethylene acrylic acid copolymer, and DuPont™ Selar® barrier resins. We also provide proven application development expertise and technical support to ensure your beverage packaging solution works for today and tomorrow.
Nucrel® for Juice Boxes
To preserve a perishable product like fruit juice, Nucrel® is used to laminate together an inner layer of polyethylene film and an outer layer of aluminum foil. This prevents the often-aggressive liquids from permeating to the outside. It also prevents the box structure from falling apart (delamination), which would then cause unwanted oxygen to penetrate the box and spoil the juice. With its superior bond strength and excellent resistance to acids, Nucrel® is the adhesive of choice for major juice box manufacturers.
Selar® PA forPlastic Bottles
Beverage packaging must control oxygen transmission in order to preserve freshness, especially for juice. In plastic bottles, a layer of Selar® PA amorphous nylon resin blended with EVOH provides a superior oxygen barrier at a lower cost than EVOH alone. Selar® PA also outperforms EVOH under cold, wet conditions. Selar® PA reduces flavor scalping in gabled containers and eliminates it entirely in plastic bottles, resulting in greater product consistency and improved consumer satisfaction.
Surlyn® for Shrinkwrapping Bundled Beverages
Thanks to a heat-shrinkable film that combines polyethylene with Surlyn®, consumers can easily and safely reach for their favorite bundled mineral water, juice, or soft drink and access individual bottles without using scissors. The film offers a straight linear tear in the transverse direction, so consumers can just push a hole in the top of the package and easily pull it open.
