Ingeo is the trademark name for NatureWorks LLC's synthetic fiber made from corn.
The process to create Ingeo makes use of the carbon stored in plants by photosynthesis. Plant starches are broken down into sugars. The carbon and other elements in these sugars are then used to make a biopolymer through a process of fermentation and separation. The resulting resin, called Ingeo biopolymer (polylactid (PLA)), can then be injection molded into plastics goods, extruded for film applications, thermoformed into packaging, or extruded for use in textiles applications.
PLA is more resistant to ultraviolet light than most other synthetics. It has relatively low flammability and smoke generation. Because it is more hydrophilic than common polyester fibers, when blended with cotton and wool, the biopolymer results in lighter garments that wick moisture away from the skin.
The biopolymer is also used in packaging manufacturing. Applications can be clear, opaque, flexible, or rigid. The biopolymer is similar to polystyrene, and exhibits tensile strength and modulus comparable to hydrocarbon-based thermoplastics. Much like polyester, it resists grease and oil, and offers flavor and odor barrier. Ingeo provides heat sealability at temperatures equivalent to polyolefin sealant resins.[1]
NatureWorks LLC has a pending partnership with Europe's Resinex Group for distribution of its Ingeo biopolymer.[2]
