Special Issue Information

Dear Colleagues, 

The 3rd International Congress on Advances in the Packaging Industry—Sustainability: Products and Processes (API2021) was held virtually on 11–12 November 2021. The congress was organized by the Regional Competence Centre for Technologies (CRdC Tecnologie Scarl, www.crdctecnologie.it) and the Italian Flexible Packaging Association (Giflex, www.giflex.it). The aim of the organizers was to create a multidisciplinary forum to discuss themes worthy of further investigation in the quickly-developing field of flexible packaging, considering the perspectives of both the scientific and business worlds. 

The main topics of the congress were as follows: 

  • Advances in packaging materials and design;
  • Active and passive barrier solutions and new functionalities;
  • Food packaging safety: Emerging risks and regulatory issues;
  • Eco design, circular economy and environmental impact;
  • Lamination, printing and converting processes;
  • Hazard and safety issues in the packaging production industry;
  • Functional coating and surface treatment technologies;
  • Nanotechnologies for packaging;
  • Packaging during the time of COVID;
  • Packaging innovation in support of the European Green Deal.

Authors of selected high-quality papers presented at the congress will be invited to submit their extended version for publishing in this Special Issue of the journal Polymers dedicated to API2021. In this regard, contributions in the form of research or review articles are welcome. All invited articles will undergo a thorough peer-review process. 

We look forward to receiving your contribution.

The purpose of this study is to limit the environmental impact of packaging applications by promoting the recycling of waste products and the use of sustainable materials in additive manufacturing technology. To this end, a commercial polylactide acid (PLA)-based filament derived from waste production of bio-bags is herein considered. For reference, a filament using virgin PLA and one using a wood-based biocomposite were characterized as well. Preliminary testing involved infrared spectroscopy, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The effect of printing parameters (namely bed temperature, layer thickness, top surface layers, retraction speed, and distance) on the final aesthetics of 3D printed parts was verified. The results allow us to attest that the thermal properties of recycled polymer are comparable to those of virgin PLA and biocomposite. In the case of recycled polymer, after the extrusion temperature, bed temperature, and printing speed are estabilished the lowest allowable layer thickness and an appropriate choice of retraction movements are required in order to realize 3D-printed objects without morphological defects visible to the naked eyes. In the case of wood biocomposite, the printing process was complicated by frequent obstructions, and in none of the operating conditions was it possible to obtain an aesthetically satisfying piece of the chosen geometry (Lego-type bricks) Finally, mechanical testing on the 3D printed parts of each system showed that the recycled PLA behaves similarly to virgin and wood/PLA filaments.
