The massive use of synthetic plastics, in particular in the food packaging area, has a great environmental impact, and alternative more ecologic materials are being required. Poly(lactic) acid (PLA) and starch have been extensively studied as potential replacements for non-degradable petrochemical polymers on the basis of their availability, adequate food contact properties and competitive cost...

INTRODUCTION Confinement of biomolecules in structured nanoporous materials offers several desirable features ranging from chemical and thermal stability, to resistance to degradation from the external environment. A new generation of mesoporous materials presents exciting new possibilities for the formulation and controlled release of biological agents. Such materials address niche application...

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...
