Ingeo is a range of polylactic acid (PLA) biopolymers owned by NatureWorks.{{Cite web |date=2019-08-04 |title=Ingeo |url=https://bioplasticsnews.com/ingeo/ |access-date=2022-08-13 |website=Bioplastics News |language=en-US}} Resinex Group distributes Ingeo in Europe.[http://www.natureworksllc.com/News-and-Events/Press-Releases/2008/9-01-08-ResinexDistributor NatureWorks LLC partners with the RESINEX group to guarantee a new integrated logistics and distribution system for Ingeo resin in Europe]

Ingeo is created using carbon stored in plants via photosynthesis and takes the form of dextrose sugar. These sugars are then converted into a biopolymer through the processes of fermentation and separation. The resulting resin can then be injection molded into plastic goods, extruded for film applications, thermoformed into packaging, or extruded for use in textiles.{{Cite journal |last1=Vink |first1=Erwin T.H. |last2=Davies |first2=Steve |date=June 2015 |title=Life Cycle Inventory and Impact Assessment Data for 2014 Ingeo ™ Polylactide Production |journal=Industrial Biotechnology |language=en |volume=11 |issue=3 |pages=167–180 |doi=10.1089/ind.2015.0003 |issn=1550-9087|doi-access=free}} However, its use in textiles is limited because of its limited comfort properties. Due to its biodegradability, PLA is applied in geotextiles, where the objective is that the material over time disappears.

PLA is more resistant to ultraviolet light than some synthetic plastics and has relatively low flammability. Due to its relatively higher hydrophobic character compared to the common polyester fibers, Ingeo is often blended with cotton and wool. This blend of materials results in lighter garments that can repel more moisture.{{Citation |last1=Farrington |first1=D.W. |title=Poly(lactic acid) fibers |date=2005 |url=https://linkinghub.elsevier.com/retrieve/pii/B9781855739161500065 |work=Biodegradable and Sustainable Fibres |pages=191–220 |publisher=Elsevier |language=en |doi=10.1533/9781845690991.191 |isbn=978-1-85573-916-1 |access-date=2022-08-13 |last2=Lunt |first2=J. |last3=Davies |first3=S. |last4=Blackburn |first4=R.S.|url-access=subscription }} PLA can be disposed of in the biological waste stream. In addition, like most polyesters, it can be recycled.

Ingeo is also used in packaging and plastic bottles.{{Cite web|url=https://www.natureworksllc.com/News-and-Events/Press-Releases/2009/02-23-09-Responsible-Launch|title = NatureWorks | Significant Years for Ingeo Natural Plastics Bottles Made from Plants, Not Oil}} Its appearance can range from clear to opaque, and it can be flexible or rigid. The biopolymer is similar to polystyrene in exhibiting tensile strength and modulus comparable to hydrocarbon-based thermoplastics. Much like polyester, it resists grease and oil. Similarly, it also offers a flavor and odor barrier.{{Cite web |last=John |first=Rojan |date=March 2011 |title=POLY LACTIC ACID: AN ENVIRONMENTALLY FRIENDLY BIODEGRADABLE POLYMER |url=https://www.researchgate.net/publication/236694764 |website=ResearchGate}} Ingeo provides heat seal-ability at temperatures equivalent to those of polyolefin sealant resins.From corn to plastics.
