Ingeo is a range ofpolylactic acid (PLA)biopolymers owned byNatureWorks.[1] Resinex Group distributes Ingeo in Europe.[2]
Ingeo is created usingcarbon stored inplants viaphotosynthesis and takes the form ofdextrose sugar. These sugars are then converted into abiopolymer through the processes offermentation and separation. The resulting resin can then beinjection molded intoplastic goods, extruded for film applications, thermoformed into packaging, or extruded for use intextiles.[3] 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 toultraviolet light than some synthetic plastics and has relatively low flammability. Due to its relatively higherhydrophobic character compared to the commonpolyester fibers, Ingeo is often blended withcotton andwool. This blend of materials results in lighter garments that can repel more moisture.[4] PLA can be disposed of in the biological waste stream. In addition, like most polyesters, it can be recycled.
Ingeo is also used inpackaging andplastic bottles.[5] Its appearance can range from clear to opaque, and it can be flexible or rigid. The biopolymer is similar topolystyrene in exhibitingtensile strength and modulus comparable to hydrocarbon-basedthermoplastics. Much likepolyester, it resistsgrease and oil. Similarly, it also offers a flavor and odor barrier.[6] Ingeo provides heat seal-ability at temperatures equivalent to those ofpolyolefin sealant resins.[7]
