Ingeo
From Wikipedia, the free encyclopedia
Ingeo is a range of polylactic acid (PLA) biopolymers owned by NatureWorks.[1]

Ingeo is created using carbon stored in plants via photosynthesis, and it is in the form of dextrose sugar. These sugars are then converted into a biopolymer through the process of fermentation and separation. The resulting resin can then be injection moulded into plastic goods, extruded for film applications, thermoformed into packaging, or extruded for use in textiles.[2]
PLA is a renewable biomass plastic that is more resistant to ultraviolet light than some synthetic plastics and has relatively low flammability. Because PLA is more hydrophobic than the common polyester fibers, Ingeo is often blended with cotton and wool to result in lighter garments ones that repel more moisture.[3]
Ingeo is also used in packaging, including bottles like those used for mineral water, which can be found in stores (e.g. in Italy[4]). Its appearance can range from clear to opaque, and it can be 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 a flavour and odor barrier.[5] Ingeo provides heat seal-ability at temperatures equivalent to those of polyolefin sealant resins.[6]
Resinex Group distributes Ingeo in Europe.[7]
