Nanocomposite Formulations from Biodegradable Polymers and Methods of Making Those

IntroductionHigh-barrier packaging is of interest to those packaging products in the food, pharmaceutical, medical, chemical and cosmetics industries. It is required to protect packaged products from the infiltration of unwanted gases, water vapor and flavors. High-barrier films are usually achieved by co-extrusion, lamination, coating and layering...

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...

Nanoclay Modification and Compound Formulation for Foaming Linear Polypropylene

IntroductionLinear polypropylene is not ideal for making foams for sealing purposes due to poor melt strength. The attempts to overcome this limitation by cross-linking a portion of the linear polymer or by adding a long chained branched polymer have resulted in unwanted side effects, such as a reduction in recyclability. Additionally, long chain b...

Higher Efficiency Process for Preparing Clays for Use in Nanocomposites

IntroductionPolymer-clay nanocomposites are used in such applications as packaging films, containers, automobile trim and injection-molded components. Homostructured mixed ion clays used in such nanocomposites require a relatively slow and complicated process to be prepared. The existing process for preparing homoionic organoclays (a critical compo...
