Ingeo is the trademark

Trademark

A trademark, trade mark, or trade-mark is a distinctive sign or indicator used by an individual, business organization, or other legal entity to identify that the products or services to consumers with which the trademark appears originate from a unique source, and to distinguish its products or...

 name for NatureWorks LLC

NatureWorks LLC

NatureWorks LLC is a subsidiary of Cargill. NatureWorks produces a family of polymers derived entirely from annually renewable resources - namely plants - designed to compete with petroleum-based plastic packaging materials, consumer goods and fiber products...

's synthetic fiber

Synthetic fiber

Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general, synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes into the air, forming a thread...

 made from corn

Corn

Corn is the name used in the United States, Canada, and Australia for the grain maize.In much of the English-speaking world, the term "corn" is a generic term for cereal crops, such as* Barley* Oats* Wheat* Rye- Places :...

The process to create Ingeo makes use of the carbon

Carbon

Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds...

 stored in plants by photosynthesis

Photosynthesis

Photosynthesis is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can...

. Plant starches are broken down into sugars. The carbon and other elements

Chemical element

A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. Familiar examples of elements include carbon, oxygen, aluminum, iron, copper, gold, mercury, and lead.As of November 2011, 118 elements...

 in these sugars are then used to make a biopolymer

Biopolymer

Biopolymers are polymers produced by living organisms. Since they are polymers, Biopolymers contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers based on the differing monomeric units used and the structure of the biopolymer formed...

 through a process of fermentation

Industrial fermentation

Industrial fermentation is the intentional use of fermentation by microorganisms such as bacteria and fungi to make products useful to humans. Fermented products have applications as food as well as in general industry.- Food 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

Polyester

Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate...

 fibers, when blended with cotton

Cotton

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective capsule, around the seeds of cotton plants of the genus Gossypium. The fiber is almost pure cellulose. The botanical purpose of cotton fiber is to aid in seed dispersal....

 and wool

Wool

Wool is the textile fiber obtained from sheep and certain other animals, including cashmere from goats, mohair from goats, qiviut from muskoxen, vicuña, alpaca, camel from animals in the camel family, and angora from rabbits....

, 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

Polystyrene

Polystyrene ) also known as Thermocole, abbreviated following ISO Standard PS, is an aromatic polymer made from the monomer styrene, a liquid hydrocarbon that is manufactured from petroleum by the chemical industry...

Thermoplastic

Thermoplastic, also known as a thermosoftening plastic, is a polymer that turns to a liquid when heated and freezes to a very glassy state when cooled sufficiently...

s. 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.

Distribution

NatureWorks LLC has a pending partnership with Europe's Resinex Group for distribution of its Ingeo biopolymer
