090127: Method to Improve Membrane Structures in Active Packaging Systems

Active packaging systems are desirable for specialized applications in the packaging of foods, chemicals, and medicines. Active packaging refers to the way materials embedded in the packaging membrane interact with the product to improve its shelf life, quality, and safety. Materials such as zeolite, alumina, and silica have been previously ad...

090023: Microperforated Polylactic Acid (PLA) Packaging Systems and Method of Preparation

Advanced 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 marketa...

090011: Fabrication and Characterization of Biodegradable PLA-Zeolite Composites

Modified 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 packag...

080011: B-Cyclodextrins as Nucleating Agents for Polylactide (PLA)

Polylactic 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 of P...

070021: Poly (1,4-benzodioxepin-3-alkyl-2,5-dione)s: Degradable Polymers with High Glass Transition Temperatures

Polylactic 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. Manipula...

000020: Process for the Preparation of Polymers of Dimeric Cyclic Esters

Polylactic 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 mono...
