Special Issue Information

Dear Colleagues,

From the earliest experimental evidence of the effects that nanometric sizes determine with respect to chemical and physical-chemical properties of materials, the packaging industry, in general, and that of food packaging, in particular, is considered to be one of the most useful application of nanotechnology.

There is a strong interest in significantly improving the performance of packaging materials, especially flexible ones, in order to improve the protective features of packaging and to increase the overall sustainability of the related industry by reducing the mass of material used and optimizing their usage.

Nowadays, it is well known that the nanometric scale can lead to relevant advantages in controlling diffusional phenomena, such as migration or permeability, in enhancing mechanical properties, and in the modulation of important surface behaviors, such as scalping or wettability. Moreover, the finalization of these properties, towards functional structures or devices, enables the introduction of active and intelligent concepts into food packages.

However, many technological aspects related to the production of coatings and composite structures have yet to be fully resolved in order to achieve real and useful applications of nanomaterials in the food packaging sector. In addition to these issues, furthermore, it is essential to take into account the themes of compliance with official regulations and the safety of food contact materials that contain nanoparticles.

The aim of this Special Issue is to attract world leading researchers in the Food Packaging area in an effort to highlight the latest progresses, discuss the underlying physics and chemistry of various achievements, and promote effective applications of nanomaterials and nanotechnology in the food packaging field. Contributions dealing with theoretical investigations, experimental verifications, and proposals of real applications will be therefore welcomed to the special issue "Nanotechnology in Food Packaging".

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Three plastic nanocomposites containing the nanomaterials silver, titanium nitride, and laponite were investigated on the potential to release nanoparticulates under stress conditions into food simulants. Nanocomposites were exposed to thermal, chemical, and mechanical stress followed by mechanical abrasion of their surface. Particle sensitive [...] Read more.
Three plastic nanocomposites containing the nanomaterials silver, titanium nitride, and laponite were investigated on the potential to release nanoparticulates under stress conditions into food simulants. Nanocomposites were exposed to thermal, chemical, and mechanical stress followed by mechanical abrasion of their surface. Particle sensitive asymmetric flow field-flow fractionation (AF4) with multi-angle laser light scattering (MALLS) as well as inductively coupled plasma mass spectrometry (ICP-MS) detection was used to detect and quantify the respective nanoparticulates. The results of this study demonstrate that even under dynamic stress conditions nanoparticulates are not released from the nanocomposites into food. Full article

Plastic and rubber based composites containing carbon black (CB) were investigated for the potential to release CB nano-particulates under stress conditions into food simulants. Nanocomposites were exposed to thermal, chemical, and mechanical stress, followed by mechanical abrasion of their surface. Particle sensitive asymmetric flow field-flow fractionation (AF4) with multi angle laser light scattering (MALLS) detection was used to detect and quantify CB nano-particulates. This study demonstrates that, even under dynamic stress conditions, CB nano-particulates are not released from the plastic or rubber compounds into food. This study intends also to propose a general nano-release stress test protocol for plastic materials coming into contact with foodstuff. Full article
