“…The O2 concentration in the packaging is determined by the residual O2 after packaging, the respiration or consumption of O2 by the product, and by the O2 ingress during the shelf life (OTR) [34,35]. The simulation software PredOxyPack ® is a practical tool to predict the oxygen ingress for different packaging configurations, materials, and time-temperature profiles [36]. In this way, realistic estimations can be made for the circumstances to which food is exposed during its preservation including cold chain conditions [37].…”

During thermoforming, plastic sheets are heated and subsequently deformed through the application of mechanical stretching and/or pressure. This process directly impacts sheet properties such as material thickness in walls, corners, and bottom, crystallinity in the constituent layers, and particularly the oxygen gas permeability. The aim of this study was to quantify the impact of thermoforming on thickness and oxygen transmission rate (OTR) of selected packaging materials (polypropylene (PP); PP/ethylene-vinyl alcohol co-polymer/PP (PP/EVOH/PP); polystyrene/EVOH/polyethylene (PS/EVOH/PE); amorphous polyethylene terephtalate/PE (APET/PE); APET/PE/EVOH/PE; polyamide/PE (PA/PE); and (PE/)PA/EVOH/PA/PE). These materials were extruded in two different thicknesses and thermoformed into trays with the same top dimensions and variable depths of 25, 50, and/or 75 mm and a 50 mm tray with a variable radius of the corners. The distribution of the material thickness in the trays was visualized, showing the OPEN ACCESSPolymers 2014, 6 3020 locations that were most affected by the deep drawn process. The OTR results indicate that the calculated OTR, based on a homogeneous material distribution, can be used as a rough approximation of the measured OTR. However, detailed analysis of crystallization and unequal thinning, which is also related to the tray design, remains necessary to explain the deviation of the measured OTR as compared to the predicted one.

“…It is interesting to make positive use of such an interaction to ensure a sustained delivery of an active substance such as the antioxidant into the food stuff. In that aim, active packaging is now increasingly used as a reservoir for active substance delivery [34][35][36][37], complementing other techniques such as modified atmosphere packaging [38], edible coating [39,40] or oxygen scavengers [41,42].…”

Potential of Lignins as Antioxidant Additive in Active Biodegradable Packaging Materials

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Abstract Due to their polyphenolic structure lignins bear a number of interesting functional properties, such as antioxidant activity. Natural antioxidants are very much looked for in the aim of protection of light or oxygen sensitive goods and are being used in active packaging. Poly(lactide) (PLA)-lignin films were prepared by twin screw extrusion followed by thermo-compression using two different commercial sources of alkali lignins obtained from gramineous plants. A good dispersion of lignin in the matrix was observed. Mechanical properties of the compounded material were merely diminished and oxygen barrier properties slightly enhanced. The chromatographic study of the lignins revealed that the low molecular weight fraction of both lignins increased during the polymer processing. The migration of low molecular weight compounds in an ethanol/water solution simulating fatty foodstuff was performed and the antioxidant activity of the extract was analysed. It was found that the activity increases with increasing severity of the heat treatment because of the generation of free phenolic monomers during processing. These results open an interesting way for application of lignins as an active compound in packaging materials. Lignins do not impair the mechanical and barrier performance of the polymer and the plastics processing even allows for the generation of active substances.

“…In order to improve the gas barrier properties of PET, a multi-layer bottle having a 3-layer structure of PET/gas barrier resin/PET or a 5-layer structure of PET/gas barrier resin/PET/gas barrier resin/PET are proposed. Typical examples of a gas barrier resin include an ethylene-vinyl alcohol copolymer (EVOH) and MXD6 nylon and approximately 80% of barrier PET bottles on the market today have a multi-layer structure (Van Bree et al, 2010).…”
