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...

High Impact-High Stiffness Bacterial Bioplastic

Description of TechnologyThis technology is a new approach for producing biodegradable plastic that overcomes some prior limitation inherent in the use of Polyhydroxybutyrate (PHB). PHB is a desirable material because of its high crytallinity and water resistance. Crytallinity is when chains pack closely together in a regular way, allowing stronger...

Environmentally Friendly Polylactide-Based Biocomposite Materials for Flooring

IntroductionThe growing environmental awareness, increasing societal concern and new environmental rules and regulations have triggered a paradigm shift in designing and engineering of eco-friendly green materials for flooring applications. Polylactic acid (PLA) polymers or polylactides are useful biodegradable polymers because of their origin from...

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

Introduction 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....

A Composition and a Method for Preparing PLA with Improved Performance Characteristics

IntroductionPolylactic acid (PLA) is an increasingly popular alternative to petrochemical-based plastics. It is biodegradable, thermoplastic, and derived from renewable resources. However, there are several major drawbacks associated with PLA, including low elongation at break, poor impact strength and heat deflection temperature. Plasticizers are used...
