New, renewably-sourced DuPont™ Biomax® Thermal extends use of PLA to higher temperature packaging applications

23.09.2008
DuPont Packaging has announced the expansion of its DuPont™ Biomax® packaging offerings to include renewably-sourced Biomax® Thermal 300, a proprietary heat-stabilizing modifier that allows polylactic acid (PLA) thermoformed packaging to withstand elevated temperatures during transport, storage and use.

Its introduction extends the use of PLA, a bio-based alternative to petrochemical-derived products, to applications beyond chilled-storage packaging.

New Biomax® Thermal 300 is a U.S. Food and Drug Administration-compliant polymer modifier that increases the dimensional stability of PLA packaging materials to temperatures of up to 95°C when used at recommended levels (between 2 percent and 4 percent by weight) and in two-stage forming processes, far above temperatures that packages could be exposed to during storage and shipping. The addition of Biomax® Thermal 300 to PLA at low levels has also been demonstrated to have a minimal impact on the material’s clarity, as well as to accelerate cycle times during two-stage thermoforming. Biomax® Thermal 300 contains 50 percent renewably-sourced content by weight.

“Because it is bio-based, PLA has strong appeal in food packaging such as produce clamshells and deli trays, as well as selected industrial applications,” said Susan Homan, North American global marketing manager for sustainable materials at DuPont Packaging. “However, due to its tendency to deform at temperatures of 55°C and above, its adoption to date has been largely restricted to the packaging of chilled food and beverages. By offering a modifier that raises the working temperature of PLA, DuPont hopes to enable a broader range of applications for the material.”

Biomax® Thermal is the second modifier for PLA to be introduced by DuPont. Biomax® Strong, toughening modifier launched in 2007, improves PLA by enhancing its processibility, durability, impact strength and flexibility in rigid structures, and acts as a process aid to improve extrusion productivity. Both of these modifiers hold the added benefit of being able to be added directly to the extrusion process (versus requiring masterbatching). The market introduction of Biomax® Thermal begins in the U.S., with rollout to Europe and Asia early in 2009.

“We are firmly committed to developing sustainable solutions, including solutions that improve the performance of other sustainable offerings in the market,” Homan said. “By improving the performance of bio-based and biodegradable products, Biomax® modifiers can help the packaging industry in achieving this mutually desirable goal.”

Now more than ever, consumers expect freshness, taste and convenience in packaged foods and beverages – and industry leaders such as DuPont continue to respond with innovations in materials and technology, including science-based solutions for improved sustainability. From renewably sourced materials such as Biomax® PTT resins and Biomax® TPS resins and sheets, to weight reducing DuPont™ Surlyn® resins, DuPont offers a wide line of high-performance polymers and additives to meet global packaging needs.

DuPont – one of the first companies to publicly establish environmental goals 18 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global market.

DuPont Packaging & Industrial Polymers is a world-class manufacturer of high-performance resins and films for a variety of packaging and industrial applications. Its best known ethylene copolymer products include Surlyn® resins for packaging and industrial applications, Bynel® coextrudable adhesives, Selar® PA amorphous polyamide barrier resins, Nucrel® acid copolymers, Elvax® EVA copolymers, Elvaloy®, Elvaloy® AC, Entira™ and Fusabond® modifiers.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
