Matériaux -- Propriétés barrièresIndex. décimale : 667.9 Revêtements et enduits Résumé : Having investigated the evolution of barrier technologies in packaging, it became obvious that there is requirement to build more functionality into many substrates used in food and other packaging that provides varying degrees of preservation. The packaging market's need for products that deliver enhanced shelf life, as well as sustainable, recyclable, metal-free and waste reducing solutions can be addressed through a revolutionary approach that replaces current barrier technology with printable barrier coatings.

StratifiésIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : DOE techniques were very useful for the development of EB curable laminating adhesives. Contour plots and trend analysis were used to elucidate the effect of each adhesive component on bond strengths. Optimized compositions were identified for individual film structures. Simultaneous optimization was also used to identify the best overall adhesive for a range of film structures.
The resulting adhesive appears to have properties that are attractive for many flexible packaging applications.En ligne : https://drive.google.com/file/d/1pYoZssRL-W6BgaW6z5lRyvELwewpt3fQ/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=19995

Spectrométrie de masseIndex. décimale : 667.9 Revêtements et enduits Résumé : Organic coatings have been applied to the inside surfaces of cans intended to come into contact with food and beverages. In general, polymeric coatings are complex formulations that may contain different components such as resins, crosslinking agents, catalysts, wetting agents, etc. The most widely used type of polymeric coating is epoxy, which is obtained by the condensation of epichlorohydrin and bisphenol A, which yields bisphenol A diglycidyl ether (BADGE). The resulting finished material may have starting substances such as monomers and additives, and also non-intentionally added substances that can potentially migrate from the food contact material into the food. In the present study, a beverage can, as a model sample, was evaluated. First, the internal surface was identified as epoxy-based coating using an infrared spectrometer with attenuated total reflectance. In the second part of the work, an acetonitrile extract of the can sample was obtained in order to tentatively identify potential BADGE derivatives using a non-targeted screening by liquid chromatography coupled to tandem mass spectrometry in positive and negative atmospheric pressure chemical ionization mode. Several BADGE derivatives could be tentatively identified comparing their characteristic m/z with a homemade database developed taking into account possible starting substances used in epoxy resins.

PolycarbonatesIndex. décimale : 668.4 Plastiques, vinyles Résumé : The use of plastics in the food industry is strictly regulated. That is why only very few recyclates can be used in this field so far. In the case of recycled polycarbonate chocolate molds, for example, the recyclate does not meet the requirements for reuse as a mold. Therefore, a processing strategy for a closed loop for chocolate molds made of polycarbonate was developed at the Institute for Plastics Technology at the University of Stuttgart, Germany.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Layers of cellulose nanofibers (CNF) have great potential to be used in food packaging applications because of their oxygen and grease barrier properties. However, because of their sensitivity to moisture, they likely will need to be used in a layered structure with water vapor barrier layers. Waterborne barrier coatings (WBBC) have the potential to provide this water vapor barrier, but their performance on paper with a CNF layer has not been described in the literature. Paper that had a CNF layer was coated with three different WBBC with various levels of two different barrier pigments to improve the water vapor barrier properties of these systems. The effective diffusion coefficient of these systems was obtained by fitting the data to a two-layer diffusion model. A finite element code was used to predict the flux rate of water vapor through the barrier layers in the presence of a barrier pigment. The dangers of samples “blocking” in production have been tested as well as grease barrier properties. The presence of the CNF layer on paper is shown to improve the performance of the water vapor barrier layer, in some cases, by a factor of six. Adding barrier pigment to the WBBC improves barrier properties at low concentration by 15%, but as the concentration of pigment increases, the barrier properties decrease. The water vapor transmission rate does not decrease to the same order of magnitude as expected from simple theoretical models and the finite element calculations. This result likely is linked to fine bubbles in the coatings that are hard to remove or other defects that are generated during coating or drying. Barrier pigments remove concerns around blocking. All samples had good grease barrier properties. Note de contenu : - Table 1 : Ranking system for blocking test
