The carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared by adding three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film was investigated. The best result was obtained through the nanocomposite film contain 3% nano...

A protein packaging film was successfully prepared using whey protein concentrate (WPC) as raw material. Protein concentration, plasticizers concentration and temperature were discussed. Research results show that the increasing of protein concentration lead to decreasing barrier properties of WPC film but improving its mechanical properties. Though barrier properties of WPC film lost to some e...

In the fresh produce industry, corrugated containers must be made to provide adequate protection throughout the product life cycle. In response to increasing materials costs in the corrugated industry, companies are focusing upon developing more efficient packaging designs. The scope of this project focuses on presenting alternative corrugated packaging designs for the fresh produce industry. I...

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...

Plastic is readily available and inexpensive, so it is becoming the main material for packaging. Unfortunately plastics do not biodegrade and, if reduced in small pieces, contaminate soil and waterways. In the present work, natural films composed of chitosan, methylcellulose, and silica (SiO(2)) nanoparticles (NPs) were developed as new packaging materials. The effect of the incorporation of NP...

Food commodities are packaged and hygienically transported to protect and preserve them from any un-acceptable alteration in quality, before reaching the end-consumer. Food packaging continues to evolve along-with the innovations in material science and technology, as well as in light of consumer's demand. Presently, the modern consumers of competitive economies demands for food with natural qu...

The packaging of double-stranded DNA into bacteriophages leads to the arrangement of the genetic material into highly-packed and ordered structures. Although modern experimental techniques reveal the most probable location of DNA inside viral capsids, the individual conformations of DNA are yet to be determined. In the current study we present the results of molecular dynamics simulations of th...

This paper reports a new packaging method for a wide range of MEMS for application on both the wafer and device scale. Titanium is used as the packaging material in this work and both silicon and titanium MEMS devices are integrated on to a titanium substrate. A Nd:YAG pulsed laser is used to micro-weld the titanium cap to the substrate. A three-dimensional time dependent model of heat flow dur...

Cattle slurry and card packaging were used to improve the operational stability of food waste digestion, with the aim of reducing digestate total ammoniacal nitrogen concentrations compared to food waste only. Use of cattle slurry could have major environmental benefits through reducing greenhouse gas emissions associated with current management practices; whilst card packaging is closely linke...

The widely accepted and used migration models that describe the mass transport from polymeric packaging material to food and food simulants are confirmed here. A critical review of the most accepted models is presented in detail. Their main advantages and weak points, regarding their predictive accuracy, are discussed and weighted toward their usage extensiveness. By identifying the specific ar...
