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, Selar® PA offers the crystal clarity of glass, but with lower weight and better impact resistance. Selar® PA can be blended with nylon 6 and with EVOH to provide certain property and processing advantages.

DuPont™ Elvaloy® AC acrylate copolymers can be processed easily on conventional equipment used by packaging film converters and offer melt strength and thermal stability advantages versus other similar copolymers. As a result, these resins can be used for improved soft touch or drape, without sacrificing service temperatures or processing ease.

Highly compatible with low-density polyethylene (LDPE), these resins easily bond to various polar and non-polar substrates, enabling use in blends for controlled peel/seal adhesion, for example.

Elvaloy® AC resins also can be used to boost the physical performance of other materials, such as adding low-temperature toughness to CPET trays or improving the formability or handling characteristics of films or sheet materials.

DuPont™ Elvax® EVA resins are a leading choice for efficient manufacturing of consumer and industrial goods. In packaging applications, the resins can be made into blown, extruded, cast and coextruded films, or blended with other resins. Inherently flexible, tough and clear, Elvax® resins also can be molded or extruded into soft plastic goods including hoses and tubes, formulated into hot melt adhesives, or used in plastics compounding, wire and cable insulation, and solar cell encapsulants.

Fusabond® coupling agents offer new levels of functionality in wood polymer composites and other wood alternatives.

Surlyn® resins are ethylene methacrylic acid (E/MAA) copolymers in which part of the methacrylic acid is neutralized with metal ions such as zinc (Zn) or sodium (Na). Surlyn® resins can be used in adhesion promotion, toughening and polymer compatibilizing, with functionality influenced by the comonomer content, acid neutralization level (ion clusters), type of metal ion (sodium or zinc), and termonomer content.

Polymer modification roles for Surlyn® include promoting adhesion to metals, PA adhesion promotion, PA toughening, PET crystallization aid PA/PE compatibilizing.

Masterbatch resins are used to disperse a high concentration of pigment and/or additives to modify the virgin polymer material. DuPont™ Elvaloy® AC Polymer Modifiers offers broader compatibility with polar and non-polar resins relative to polyethylene carriers or conventional acrylate copolymer resins. It is also a more 'universal' carrier than PE or EVA resins. It provides superior thermal stability relative to EVA resins.

Grades of Entira™ Antistat are available to confer antistatic performance on a variety of polymers in food and non-food contact approved applications. Entira™Antstat grades ensure long-lasting anti-static dissipation for your demanding packaging needs.

From cosmetics to industrial goods to sensitive electronic components, only Entira™ Antistat provides permanent antistatic performance with superb aesthetics, clarity, non-yellowing, dust-free protection.

DuPont™ Bynel® coextrudable adhesive resins, which are often called tie layers, help packaging manufacturers 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.

Fusabond® maleic anhydride grafted resins can be used as coupling agents between polymers -- mainly polyolefins such as polyethylene and polypropylene -- and fillers, in order to increase the filler acceptability of polymers. It also provides improvement in polymer properties like impact strength and moisture resistance. Grade selection depends on specific polymer matrix requirements.
