This accelerated shelf life study of a ready-to-eat meal processed with microwave-assisted thermal sterilization (MATS) system aimed to evaluate the performance double metal oxide coated polyethylene terephthalate (PET) layers-based ultra-high barrier packaging along ethylene vinyl alcohol (EVOH)-based pouches, and aluminum (AL) foil-based pouches (served as control). First, we evaluated change...

Barrier systems are designed to control contaminant migration. Geomembranes are commonly used as part of a composite liner in landfill cover, base liner systems and sometimes vapour barriers. In landfill applications, the primary function of the geomembrane liner is to control contaminant transport from the leachate (dissolved phase) and landfill gas (vapour phase) out of the landfill thus mini...

A novel disposable adsorbent material for fast cation-exchange separation of proteins was developed based on plastic microcapillary films (MCFs). A MCF containing 19 parallel microcapillaries, each with a mean internal diameter of 142 μm, was prepared using a melt extrusion process from an ethylene-vinyl alcohol copolymer (EVOH). The MCF was surface functionalized to produce a cation-exchange a...

It has been shown that blends of starch with a poly(ethylene-vinyl-alcohol) copolymer, EVOH, designated as SEVA-C, present an interesting combination of mechanical, degradation and biocompatible properties, specially when filled with hydroxyapatite (HA). Consequently, they may find a range of applications in the biomaterials field. This work evaluated the influence of HA fillers and of blowing ...

In this study, the electrospinning method was used to prepare silver nanoparticle–activated carbon (AgNP-AC) composite nanofiber membranes, aiming obtain a high-performance dual-functional filter fiber membrane with good antibacterial and adsorption properties. A scanning electron microscope (SEM), X-ray diffractometer (XRD), other instruments were characterize morphology structure of nanofiber...

The aim of this study was to evaluate the influence different packaging materials [standard foil: BOPP (biaxially oriented polypropylene)/PET (polyester)/PE (polyethylene) for upper layer, and APET (polyethylene terephthalate)/PE bottom layer; foil 1: PP (polypropylene)/PET/PE/EVOH (ethylene-vinyl alcohol copolymer)/PE PP/PE/EVOH/PE 2: PP/PET/PE/EVOH/PE PA (polyamide)/EVOH/PE 3: PP/PET/PE PA/EV...

Investigations of the mechanical behaviors paperboard packaging materials has propelled to forefront industries owing anisotropic behavior materials. Paperboard undergo tensile forces during creasing and folding operation. Therefore, knowledge material properties it is undeniably important perform operation without tearing layers. Anisotropic required be addressed for used effectively efficient...

Abstract Fusarium culmorum and F. proliferatum can grow produce, respectively, zearalenone (ZEA) fumonisins (FUM) in different points of the food chain. Application antifungal chemicals to control these fungi mycotoxins increases risk toxic residues foods feeds, induces fungal resistances. In this study, a new multidisciplinary approach based on use bioactive ethylene-vinyl alcohol copolymer (E...
