Application
- Polylactic acid (PLA) biocomposite: Processing, additive manufacturing, and advanced applications: Discusses the enthusiasm towards manufacturing of biopolymers, particularly PLA, and its applications in various fields due to its favorable environmental and mechanical properties (RA Ilyas, SM Sapuan, MM Harussani, M Hakimi, 2021).
- Synthesis and applications of biopolymer composites: Highlights the development and applications of biodegradable biopolymer composites and nanocomposites, with an emphasis on PLA due to its wide use and environmental benefits (AM Díez-Pascual, 2019).
- Biopolymer blends based on poly (lactic acid): Focuses on the blending of PLA with other biopolymers to enhance its mechanical and thermal properties, vital for expanding its application scope in industrial and environmental sectors (R Al-Itry, K Lamnawar, A Maazouz, 2015).
- Migration of oligomers from a food contact biopolymer based on polylactic acid (PLA): Examines the safety and chemical characteristics of PLA when used in food packaging, focusing on the migration of its components under various conditions and their compliance with food safety standards (S Ubeda, M Aznar, P Alfaro, C Nerín, 2019).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

貴社製品ポリ乳酸についてですが、こちら顆粒の製品になるかと思います。 こちら使用時水に溶ける製品になりますでしょうか。 ご確認よろしくお願いいたします。
1 answer-
This product is not tested for solubility. Polylactic acid is a polyester. Typically, polyesters are insoluble in water, but are relatively soluble in common organic solvents such as acetone, THF, chloroform, and ethyl acetate.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
