However, these active ingredients can lose their effect due to the influence of light and temperature during storage. To prevent this, packaging can be specifically adapted to the requirements of these products in terms of light protection. In addition, the packaging also protects the products from oxidative influences. An adapted oxygen and water vapor barrier can guarantee high product quality over the storage period. Currently, there is a great demand for sustainable packaging. However, these often lead to compromises in terms of barrier properties and product quality. Current research is determining how the product’s requirement for packaging can be reconciled with sustainability. With the help of so-called digital modeling tools, product quality can be predicted over the storage period, thus facilitating sustainable packaging selection.

Nanoplatelets in a barrier lacquer / Stefan Schiessl in KUNSTSTOFFE INTERNATIONAL, Vol. 112, N° 1 (2022)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 112, N° 1 (2022) . - p. 42-45 Titre : Nanoplatelets in a barrier lacquer : Flexible and sustainable plastic packaging film thanks to nanotechnology Type de document : texte imprimé Auteurs : Stefan Schiessl, Auteur ; Esra Kucukpinar, Auteur ; Marius Jesdinszki, Auteur ; Sandro Gennen, Auteur ; Pascal Viville, Auteur ; Oliver Douhéret, Auteur Année de publication : 2022 Article en page(s) : p. 42-45 Langues : Anglais (eng) Catégories : Aliments -- Emballages Emballages en matières plastiques Enduction Laque et laquage Matériaux -- Propriétés barrières Nanoparticules Polyacétate de vinyle Polypropylène Stratifiés Index. décimale : 668.4 Plastiques, vinyles Résumé : Within the "BarriFlex" joint project, novel nano-tailored materials with improved barrier properties against gas and water vapor were developed for packaging applications. These materials form the basis of new packaging concepts. Despite intensive research, much still remains to be done as regards diversity of materials, barrier specifications and more efficient manufacturing processes for new, inexpensive, easy-to-recycle and even renewable packaging products. Note de contenu : - Nanolacquer formulation - Manufacture of mono-material laminates for food packaging - Atomic layer deposition and laminate structures for organic photovoltaics - Fig. 1 : Top: the integration of platelet-shaped, impermeable nanoparticles extends the diffusion path. Bottom: scanning electron image of an adequate PVA coating without (left) and with (right) nanoparticles - Fig. 2 : Coating of a PP film with nanolacquer containing 50 wt. % nanoparticles using the slot die technique. Right: schematic diagram of a roll-to-roll coating unit - Fig. 3 : Oxygen permeation rate for different mono-material laminates. The left bar shows a blank sample without an active barrier layer (to show the differences between the other samples, this bar has been truncated). The industrial standard is a co-extruded high barrier film, which is commercially available. The two samples on the right show the new development within the BarriFlex project and the improvement factor achieved by integrating nanoparticles - Fig. 4 : Optimization of the ALD chamber: (a) initial chamber, (b) schematic and (c) resulting substrate holder specifically made in the BarriFlex project along with (d) modified chamber cap En ligne : https://drive.google.com/file/d/1xQBAprfO_KzZreXoE7v6BFDqY_1lHDds/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37209 [article]
