FOOD CONTACT STATUS: In the European Union, Luminy® PLA polymers are compliant with EU commission regulation 10/2011 of 14 January 2011 (and amendments) on plastic materials and articles intended to come into contact with food. Lactic acid is considered a dual use substance, since lactic acid is approved as a food additive (additive number E270). There are no SMLs or SML(T)s for the ingredients used to produce Luminy® PLA. The regulation does include an migration limit of 10 mg/dm2 on the overall migration from finished plastic articles into food. It is the responsibility of the manufacturer of the final product, when intended as a food contact product, to determine that the use of the product is safe and also suitable for the intended application. While it is Total Corbion PLA’s conclusion that the above mentioned polymers are permitted, it is the final product which must meet the given regulations and the manufacturer should take responsibility to check if the final product is in compliance with these regulations.
In the United States of America, Luminy® PLA as supplied by Total Corbion PLA has been evaluated and was found to be suitable for use in food contact applications. On 30 November 2018, FCN 001926 as applied for by Total Corbion PLA to the FDA became effective. It is included in the list of effective notifications for FCNs on the website of the FDA. The evaluation performed was in line with the requirements of Section 201(s) and Section 409 of the Federal, Drug and Cosmetic Act, and Parts 182, 184 and 186 of the Food Additive Regulations. Luminy® PLA neat resin is approved for all food types and conditions of use B through H.
NOTICE REGARDING USE RESTRICTIONS: Unless specifically agreed to in writing, Total Corbion PLA will not knowingly market any product into any of the following commercial or developmental applications:
Luminy® LX930 can be processed on conventional extrusion spinning and drawing equipment. Thorough cleaning is highly recommended due to the incompatibility of PLA with a wide variety of polymers. In case of spinning PLA after another polymer resin, it is recommended to not install the spin pack until an even homogeneous flow of PLA is observed. Pre-drying of the resin is recommended. Typical melt spinning temperatures are 220-240°C.
MOISTURE & PRE-DRYING: It is recommended to dry Luminy® LX930 from the packaging for 24 hours at 40°C. Drying of standard PLA can be performed in a desiccant hot air dryer, with a dew point of -40°C or less. Drying at higher temperatures can result in pellet sticking and clogging of drying and conveying equipment. It is recommended to reduce the moisture content before spinning to a level preferably less than 100 ppm, measured by e.g. Karl-Fischer or Brabender aquatrac method. Moisture causes hydrolysis of the PLA polymer during melt processing, resulting in process instabilities and possibly decreased mechanical properties.
