PLA is a biobased plastic derived from natural resources and offers a significant reduction in carbon footprint compared to oil-based plastics. Corbion Purac uses carbohydrates as the raw material to produce lactic acid via a fermentation process, which is polymerized via the lactide intermediate into PLA. PLA is currently being used in a variety of applications like packaging and food serviceware, and is increasingly becoming the material of choice for more demanding applications in automotive, electronics and textiles.

Corbion Purac offers a number of PLA grades based on stereochemically pure monomers. This new portfolio of neat PLA resins includes products in three categories:• PLLA homopolymers for injection molding (L105, L130)
and extrusion/thermoforming (L175),• Standard PLA for extrusion/thermoforming (LX175),• PLLA homopolymers (L130, L175) and standard PLA
(LX175) for fiber spinning• PDLA homopolymers as a nucleating agent for PLLA
homopolymers (D070).
Corbion Purac’s neat PLA resins are compliant with the most relevant regulations and requirements related to bioplastics:• Approved for use in food contact applications (EU
Framework Regulation EC No. 1935/2004 and No. 10/2011),
• Compliant with EN13432 standard for industrial composting,
• Biobased content of 100%,• REACH compliant,• Exclusively made from non-GMO feedstocks,• Reduced carbon footprint - 3rd party LCA study

PLA is an acronym that describes not just one product, but a range of different polymers. PLA resins are available in a range of stereochemical purities and viscosities, resulting in different properties (see figure 2 and the table below).
PLA homopolymers
Corbion Purac’s PLA homopolymer resins are available in a range of melt viscosities and deliver improved heat resistance over standard PLA. These grades can be used as neat resin or as part of a compound in order to further optimize overall material properties. In order to obtain improved heat resistance over standard PLA, these resins need to crystallize during processing.• PLA L105 is a high flow resin suitable for injection molding.• PLA L130 is a medium flow resin suitable for injection
molding and fiber spinning.• PLA L175 is a low viscosity resin suitable for film extrusion,
thermoforming or fiber spinning.
Standard PLA
• PLA LX175 is a low viscosity, amorphous, transparent resin, suitable for film extrusion, thermoforming or fiber spinning.
PDLA
PDLA, when combined with PLA homopolymers, will yield a compound that combines good heat resistance with excellent mechanical properties and a reduced processing cycle time (see figure 3). Typical nucleated formulations should include 3-7% PDLA.• PDLA D070 is a general purpose nucleating agent for PLA
homopolymer resins.
