Fabrication and Characterization of Biodegradable PLA-Zeolite Composites (Includes TEC2007-0123)

IntroductionModified Atmosphere Packaging (MAP) enhances quality, extends the shelf life of perishable foods, and prevents loss revenues due to food spoilage. MAP is required because the balance and interaction of certain gases, such as carbon dioxide (CO2) and oxygen, with packaged foods contributes to either poor or high food quality. Advances in...

Microperforated Poly(lactic acid) Packaging Systems and the Method of Preparation Thereof

IntroductionAdvanced packaging systems are required to ensure the quality of fresh produce for consumers, who often purchase the products several days after harvest. Supply chain distances are expanding to increase gains in geographical market share for fresh produce growers, which require a longer shelf life to present the product to consumers in marketable...

B-Cyclodextrins as Nucleating Agents for Polylactide (PLA)

IntroductionPolylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics for packaging and other applications. It is biodegradable, thermoplastic, and derived from renewable resources. However, there are characteristics associated with PLA that limit its workability. Particularly, the slow crystallization rate...

Poly (1,4-benzodioxepin-3-alkyl-2,5-dione)s: Degradable Polymers with High Glass Transition Temperatures

IntroductionPolylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. However, polylactides must be crystalline tor them to be dimensionally stable above 50° C, which is a characteristic that limits its use for some applications....

Process for the Preparation of Polymers of Dimeric Cyclic Esters

IntroductionPolylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. Presently, the preparation of crystalline materials requires enantiopure L-lactide, where lactic acid is produced by microbial fermentation, and the cyclic lactide...
