The huge difficulty recorded in the years about the disposal of an increasing amounts of plastic items at the end of their useful Life has significantly influenced the choice of new materials in almost all industrial fields favouring the development of innovative eco-friendly solutions. In light of this consideration, under a national project, funded by the Research Ministry and specifically related to the luggage field, authors focused their attention on the production of new environmentally friendly suitcases based on the use of plastic scraps from the recycling chains and the use of biodegradable resins or coming from renewable resources. In the first case, recycled polyesters from bottle flakes were adequately modified by inclusion of opportune toughening and chain extender agents to meet quantitative specifications of the reference market. Alternatively, different commercial grades of poly(lactic acid) and poly(hydroxy alkanoates) resins have been considered still including organic modifiers to improve mechanical performances of products and natural reinforcement fabrics as cotton, jute and flax. All materials, always modified by reactive extrusion and transformed in pure sheets or woven fabric reinforced laminates by compression moulding, were characterized in terms of mechanical properties under static, dynamic and impulsive conditions, highlighting good perspectives for the reference applications. Suitcase prototypes, specifically designed in order to further improve mechanical performances of products and based on some selected formulations, were produced by thermoforming and validated by specific tests. Results confirmed a significant competitiveness of new eco-sustainable rigid suitcases with respect to commercial ones. [ABSTRACT FROM AUTHOR] |
