We have everything you need to help you transform your innovative designs into packaging reality.
DuPont™ Bynel® adhesive resins
DuPont™ Bynel® coextrudable adhesive resins, often called tie layers, help packaging manufacturers bring together and optimize barrier, heat seal and other functions in multi-layer structures such as films, bottles, tubes and thermoformable sheet. DuPont offers the packaging industry's broadest selection of these specialized resins.
DuPont™ Selar® resins
DuPont™ Selar® PA amorphous nylon barrier resins provide unique oxygen barrier properties when wet or chilled, making the resins a perfect choice for flavor-sensitive refrigerated foods and beverages. In bottles, jars and other rigid structures, DuPont™ Selar® PA amorphous nylon resin offers the crystal clarity of glass, but with lower weight and better impact resistance. DuPont™ Selar® PA amorphous nylon resin can be blended with nylon 6 and with EVOH to provide certain property and processing advantages.
France’s Chamois d’Or Cheese gets perfect packaging
Packaging converter Lawson Mardon Morin worked with DuPont to develop a permeable packaging film that would be ideally suited to soft cheese with surface mold. DuPont™ Bynel® adhesive resin and DuPont™ Selar® PA amorphous nylon resin were chosen for this unique application because in combination they give the packaging film specific barrier properties and optimize the cheese maturation.
DuPont offers structural polymers able to support high quality decoration for rigid packaging
- DuPont™ Delrin POM resins for functional and appealing parts such as valves or springs and pressure resistant containers.
- DuPont™ Rynite® PET resins for heat resistant packaging
- DuPont™ Hytrel® thermoplastic polyester elastomers for bellows, dispensing systems, seals with good chemical resistance, maintaining properties at high and low temperatures.
- Resins for Dispensing systems
Closures and dispensing systems are a fertile area for new product development and a key means of adding value, convenience and differentiation to brands and packs in an increasingly competitive global marketplace.
DuPont engineering polymers can create innovative designs to match market needs with cost effective solutions. Can provide greater functionality and performance while improving environmental friendly image. Addressing consumer needs and adding new “experiences” while using.
For example, the outstanding fatigue and creep resistance resistance of DuPont™ Hytrel® thermoplastic polyester elastomers ensures valves and buttons functionality even after storage at high or low temperatures while having design versatility and reducing number of parts.
