DuPont demonstrates sustainability at interpack 2008


Biomax TPS, based on technology from DuPont`s alliance partner Plantic Technologies Limited, ranges in renewable content up to 90 percent. Both injection molding grades and thermoformable sheet grades are certified industrial compostable, while the sheet grades are also certified home, soil, and marine compostable. Potential applications include thermoformed packaging trays, rigid containers in the food, cosmetics & personal care industries, and formed articles intended for short-life and easy-disposal.

Biomax PTT is a partially renewably-sourced, high-performance copolymer of 1,3 propanediol and terephtalic acid with polyester-like performance, suitable essentially for use in injection-moulded products targeted applications for the new resin include injection moldable containers and other parts where today polyesters are used. Biomax PTT can be characterised through excellent scratch and chemical resistance similar to PET and PBT.

A further technology launch scheduled for Interpack 2008 is the result of a joint development agreement between DuPont and French company Coldpack. Providing an alternative to expanded polystyrene (EPS) for temperature controlled shipping of perishable goods and thermal sensitive products, the Coldpack concept is based on an inflatable heat barrier technology.

Using DuPont Bynel adhesive resins and DuPont Surlyn for its outer- and inner layers, as well as a specially-developed grade of metalized Surlyn for its honey-combed structure, the inflatable airliner provides equivalent insulation and protection to EPS foam packaging, at reduced shipping and handling costs and with a reduced impact on the environment.

Finally, reflecting DuPont`s sustainable theme for Interpack 2008, the winners of the 20th DuPont Awards for Packaging Innovation will be announced at the show. Consistent with the company`s own commitment to reducing its environmental footprint, the DuPont Packaging Awards now honour materials, processing, technology and service achievements that demonstrate progress toward sustainability, while also meeting important market requirements for enhanced performance such as improved freshness, convenience and shelf appeal.
