Biopolymer films containing chitosan as antimicrobial agent were obtained. As polymer matrix poly(vinyl alcohol) (PVA) and bacterial cellulose (BC) were used. The films were characterized using FTIR spectroscopy. FTIR spectra of the pure components and of composites films reveal strong interactions between chitosan and PVA and chitosan and bacterial cellulose. These composite films could be use...

In this article, several applications of nanomaterials in food packaging and food safety are reviewed, including: polymer/clay nanocomposites as high barrier packaging materials, silver nanoparticles as potent antimicrobial agents, and nanosensors and nanomaterial-based assays for the detection of food-relevant analytes (gasses, small organic molecules and food-borne pathogens). In addition to ...

Petroleum-based polymers have served the packaging industry in numerous ways as films, pouches, rigid containers, foamed and other components for food, medical, applications. However, growing concerns about environmental impact, awareness of greenhouse gas emission their adverse effects, increased oil prices, disposal landfill issues are forcing researchers to develop sustainable packaging. Bio...

The article presents the latest solutions for sustainable flexible packaging materials, covering articles published in 2017–2022. Discussed, among others bio-based, biodegradable, and recycled polymers, paper, which are slowly being adopted by industry expected to replace traditional materials from non-renewable sources coming years.

Protein-based edible films have received consideration attention in recent years because of their advantages, including their use as edible packaging materials, over the synthetic films. In addition, protein-based edible films can also be used for the individual packaging of small portions of food, particularly products that are not currently individually packaged for practical reasons, such as...

The sawtoothed grain beetle, Oryzaephilus surinamensis (L.), is an important pest of packagedconsumer foods, yet little is knownof its behavioral response to foododors.Adults and larvae are not believed to chew holes through packaging materials, but they may invade packaged food by entering through openings caused by improper sealing or handling, throughholes intentionally placed in packages by...

Reliability is a key parameter for the eventual prevalence of microelectromechanical systems (MEMS) as either sub-components or as standalone products. Traditionally, micromachined components have been made by separating the micromachined chip design and fabrication processes from the packaging and reliability issues. This “evolutionary” partitioning of microsystems has led to long incubation t...
