“…Even more advanced and intriguing is the possibility of providing films with specific additional functionality, thus developing not just a passive barrier but an active component. 1 In Europe, packaging is the largest application sector for the plastics industry and represents 39.6% of the total plastics demand. It is clear that packaging, including flexible films and rigid containers, represents the largest single market for plastic material consumption and also one of the main problems when it comes to post-consumption disposal of wastes.…”

Hydroxytyrosol methyl carbonate (HTyr-MC), a synthetic non-cytotoxic hydroxytyrosol-derived compound showing excellent antioxidant capacity, was obtained in high yield and purity by an ecofriendly procedure and used as active ingredient for poly(vinyl alcohol) (PVA) matrix. Novel PVA/HTyr-MC binary films were developed by solvent casting in water adding 2%, 5% and 10% by weight of HTyr-MC to PVA. Morphological, thermal and optical properties, water absorption capacity, migration to food simulant and antioxidant characteristics of PVA/HTyr-MC films were finely investigated in view of their potential application as active food packaging materials. The morphological and transparency studies underlined that HTyr-MC was homogeneously dispersed in the PVA matrix and it is able to act as a nucleation agent, influencing the diffusion processes of the water through the polymer chain without negatively affecting the release of the active ingredient. The overall migration levels for all studied formulations were lower than the migration limits permitted by the current legislation for food contact materials while the data of antioxidant assays demonstrated a good antioxidant activity induced by HTyr-MC presence also at the lowest concentration. These novel films represent a valid and sustainable alternative to non-ecofriendly-based materials.

“…However, current consumer concerns about the use of chemical preservatives in food products are making researchers direct their efforts towards alternative compounds of natural origin, such as vegetal extracts or essential oils of herbs and spices. These latter substances, in particular, are already recognized as food additives by the European Food Safety Authority and as generally recognized as safe substances by the US FDA and have been the object of numerous studies demonstrating their effectiveness against a wide spectrum of microorganisms, as well as their advantages in matters of consumer acceptance, antioxidant activity and biodegradable or edible capabilities in recent years …”

Food packaging is the best way to protect food while it moves along the entire supply chain to the consumer. However, conventional food packaging poses some problems related to food wastage and excessive plastic production. Considering this, the aim of this work was to examine recent findings related to bio-based alternative food packaging films by means of conventional methodologies and additive manufacturing technologies, such as 3D printing (3D-P), with potential to replace conventional petroleum-based food packaging. Based on the findings, progress in the development of bio-based packaging films, biopolymer-based feedstocks for 3D-P, and innovative food packaging materials produced by this technology was identified. However, the lack of studies suggests that 3D-P has not been well-explored in this field. Nonetheless, it is probable that in the future this technology will be more widely employed in the food packaging field, which could lead to a reduction in plastic production as well as safer food consumption.
