One of the critical factors in selection of food packaging materials is permeability and/or transmission rate to help maintain food quality. Conditions of product/material use such as temperature and relative humidity are critical for determining optimal testing conditions to determine permeability rate. Basics of permeability, interpretation of data and relationship to selection of materials f...

Multilayer films are widely used in packaging industry to fulfil different applications. It is well known that multilayer structure is essential for high gas barrier packaging using EVOH, because moisture has negative effects on EVOH’s barrier properties [1, 2]. In order to effectively use EVOH in barrier applications, usually a moisture barrier layer and a tie layer are required [3, 4]. In thi...

Votavová L., Dobiáš J., Voldřich M., Čížková H. (2009): Migration of nonylphenols from polymer packaging materials into food simulants. Czech J. Food Sci., 27: 293–299. p-Nonylphenol (NP) is widely used in many industrial applications (detergents, latex paints, pesticides, and plastics), and its presence in the environment has acquired an increasing concern since it was shown to be, besides its...

Plastic packaging materials are widely used because of their advantages light weight, low cost, and convenience, especially as victuals materials. Approximately 146 million metric tons plastics were for in 2015, but most these had already been discarded followed by serious white pollution. What's worse, the materials, polystyrene (PS) foam containers, can release microplastics (MPs) during dail...

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 ...
