The aim of this work was to study the interaction of corrugated and plastic materials with pathogenic and spoiling microorganisms frequently associated to fresh produce. The effect of the two packaging materials on the survival during the storage of microorganisms belonging to the species Escherichia coli, Listeria monocytogenes, Salmonella enteritidis, Saccharomyces cerevisiae, Lactobacillus p...

The types of packages and containers in circulation are extremely wide-ranging: glass bottles, aluminum cans, detergent containers, gift-wraps, food packaging films and so forth. According to the statistics for 2007, total expenditure on packages and containers reached 6.2 trillion yen 1). The theme of this article, extrusion lamination processing, plays an important role in manufacturing paper...

D iagnostic companies are facing ever-increasing pressures to deliver new products safely and efficiently. With diagnostic reagents as the basis of any experimental protocol, it is essential that they remain highly pure and that the potential for any contamination is minimized. Reagent packaging has commonly taken the form of glass bottles and containers, which have a well-known mode of failure...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

Bisphenol A (BPA) is a chemical used for lining metal cans and in polycarbonate plastics, such as baby bottles. In rodents, BPA is associated with early sexual maturation, altered behavior, and effects on prostate and mammary glands. In humans, BPA is associated with cardiovascular disease, diabetes, and male sexual dysfunction in exposed workers. Food is a major exposure source. We know of no ...

This Laboratory Directed Research & Development (LDRD) project conducted in fiscal years 1996 and 1997 under case 3526.030 was devoted to the development of test structures and associated measurement methodology for assessing the reliability of plastic encapsulated microelectronic devices. The end goal was the conceptual specification of one or more Assembly Test Chips (ATCs) which could be use...

This experiment was carried out to increase the shelf life and maintaining the quality of mango (Mangifera indica) fruits. There were two factors. Factor A: postharvest treatments with six levels (1. untreated (control), 2. washing with chlorine, 3. dipping (5 minutes) in calcium chloride (CaCl2), 4. dipping (5 minutes) in bavistin and rinse in clean water, 5. hot water treatment and 6. tap wat...

This paper will detail the design and manufacturing elements of near hermetic air cavity packages produced by injection molding of low moisture diffusivity polymers. The R-Pak process uses a patented sealing methodology to take maximum advantage of the properties of the starting polymeric material. The material properties and advantages will be presented. The very low moisture diffusivity of th...
