Recently, DuPont is working with Archer Daniels Midland to develop a new monomeric methylfurocarboxylate (FDME). When this monomer is combined with Bio-PDO or other monomers to form a polymer, FDME has The barrier properties of carbon dioxide and oxygen are particularly suitable for beverage and food packaging.

DuPont and Archer Daniels Midland have developed FDME monomer

DuPont of Wilmington, Germany, has pioneered the biochemical process for the manufacture of Bio-PDO compounds.

The process of extracting glucose from crops to make Sorona

According to Dr. Michael Saltzberg, Head of Global Biomaterials, DuPont Industrial Biosciences, innovations in biomaterials can make plastic packaging lighter, and can extend plastic packaging to applications where metal or glass packaging is currently required due to certain limitations. .

Among these new materials, DuPont has a strong research interest in the converter and polymer brands, and is currently signing a confidential joint development agreement with major potential customers.

Bio-PDO is a molecule called 1,3-propanediol produced using DuPont's proprietary fermentation process and is a liquid made from industrial corn sugar using a fermentation process. Sorona is a polymer made from Bio-PDO and terephthalic acid, which is derived from petroleum. Sorona is typically supplied to customers as polymer pellets that can be extruded into fibers, films and molded parts.

For packaging applications, DuPont is working with Archer Daniels Midland to develop a new monomeric methyl furancarboxylate (FDME). When combined with Bio-PDO or other monomers to form a polymer, FDME has barrier properties against carbon dioxide and oxygen, and is particularly suitable for beverage and food packaging.

FDME polymers have high barrier properties for beverage and food packaging

Furan-based polymers made from FDME will be used in hard packaging that requires high barrier gases, including carbonated soft drinks, beer, carbonated water and fresh juices. At the same time, DuPont also expects FDME to be used in film packaging where barrier properties are critical, such as meat and cheese packaging.

The development of FDME and polymers made from it is DuPont's next step in the field of biomaterial packaging. For the development of FDME, DuPont plans to build a demonstration plant that can be listed in the fourth quarter of this year. The commercial plant is expected to be completed and put into production in 2021.
