Food Containers and Wrappings

Free Radicals in Plastic Food Containers

Free radicals in polymers are produced during synthesis and interaction with catalysts, initiator of chemical reactions, fillers, stabilizers, and other substances which as chemically or physically active remain dissolved in condensed phase of final product. Also γ irradiation causes both immediate and time dependent changes which arise from the presence of long living free radicals. The free r...

Wrappings for Software Development

Wrappings as Design Patterns

Design Patterns provide a \higher-level" view of interactions among collections of objects. They are a response to a common problem in large, object-oriented systems: there is no explicit representation of the patterns of activity of collections of objects. Wrappings are a Knowledge-Based integration infrastructure for constructing complex software systems, that we have developed over several y...

Migration of nanoparticles from nano-silver food containers

Based on the antimicrobial action of nano-silver, a number of “active” FCMs have been developed that are claimed to extend the shelf-life of food by inhibiting the growth of microorganisms. As commercialization of nano-silver grows, the public and the governments become more concerned about the safety and environmental effects of the widespread use of products containing nano-silver [2]. Severa...

Nanoparticle release from nano-silver antimicrobial food containers.

Polymer nanocomposites incorporating metal or metal oxide nanoparticles have been developed to improve their characteristics (flexibility, gas barrier properties, antimicrobial or antioxidant properties, etc.). Among them silver nanoparticles are used because of their antimicrobial effect in many daily life materials, i.e. food packaging. However, there is not any reference to the migration of ...
