Biomax® PTT
As a renewably sourced packaging material, DuPont™ Biomax® PTT is suitable for a variety of packaging applications including films, sealants, and rigid containers. Biomax® PTT offers very good resistance to product formulations, good barrier properties, heat sealability, printability, toughness and helps meet customer demands for packaging materials not wholly derived from petroleum.
Biomax® TPS
Biomax® TPS is a high-amylose thermoplastic starch offering which has high renewably-sourced material content (85%-90%) and is completely biodegradable with contact with water. It is offered in both sheet and resin forms. The sheet format is intended for thermoformed tray and part applications where anti-static, grease-resistance, or odor and flavor barrier properties may be desirable.
The injection molding resin grades include a general purpose grade, high-flow for thinner parts, an stiff grade for higher-strength applications, and two water-resistant grade for packages or articles that may need slightly longer useful life timing (up to 3 months). [The latter three resin grades have slightly lower renewable source content, ranging from 55-80%]. Biomax® TPS resin grades are especially useful where product or package collection after use may not be convenient.
Pro-Cote® Soy Polymer
DuPont™ Pro-Cote® is a renewably sourced, biodegradable material that imparts a combination of functional properties in coating formulations to provide rheology control, coverage, print properties, binding strength, thickening, and operational productivity for paper and paperboard manufacturers. Protein binders run well due to excellent hydration, print well, are rigid and resist heat (blocking). Pro-Cote® products are designed to give superior performance in paperboard coatings formulated with any pigment system (clay, calcium carbonate, talc, TiO2) and can be used in size press, precoat and topcoat applications with any applicator type.
Selar® VP Breathable Resin
DuPont™ Selar® VP is ideal for fresh food packagers that require high and selective gas permeability to oxygen or water vapor. Because Selar® VP packaging breathes and lets gases transfer in and out, packers can pack fresh-cut produce as well as meet FDA guidelines on products such as fresh fish. Moreover, Selar® VP has strong forming characteristics, tight clingability, good machinability, ease of cutting, and it can be processed on conventional film converting and end-use equipment.
Sorona® Polymer
As a renewably sourced packaging material, DuPont™ Sorona® is suitable for a variety of packaging applications including films, sealants, foams and rigid containers. Sorona® offers excellent barrier properties, heat sealability, printability, toughness and helps meet customer demands for packaging materials that are not derived from petroleum.
Sustainable Packaging
Through research and technological innovation, DuPont is constantly exploring new ways to reduce the impact of packaging on the environment, while delivering uncompromised performance.
