PLA4FOOD proposal deals with the development of innovative active and biodegradable packaging for fresh-cut food products based on renewable resources thermoplastic materials (PLA-polylactic acid). Fresh Cut Products category refers to fresh vegetables, fruit and market garden products without thermal treatment, prepared, washed and packaged without the incorporation of additives or preservatives and, as an essential requirement, demands the maintenance of the cold chain for its perfect conservation and has a shelf life of approximately 7 days.
Addcomp Holland B.V. is active in this project as a compounder of materials functionalised with additives from natural sources (antioxidants, antibacterial and antifungal) in order to increase the shelf-life of packed products. Different encapsulation routes will be tested to protect active additives from processing conditions and to control migration rates. PLA4FOOD aims to minimize the current limitations of PLA in terms of flexibility, water barrier properties, and processability. Different additives will be studied, including bio-based lactic-acid plasticizers, inorganic nanofillers, and organic nucleants. Co-extrusion techniques (blown-film, cast-sheet and thermoforming) will be developed to obtain multilayer structures from different PLA formulations, controlling the thickness and crystallinity of each layer, in order to achieve the best cost/benefit ratio and optimal performance of the active packaging. This combination of material advances and processing technology improvements is designed to produce high-performance, active food packaging that exceeds the current state of the art. New active and biodegradable packages from renewable sources will provide minimally processed fresh-cut products with adequate protection against environmental agents. These packaging advances will improve product properties (quality, shelf-life, microbiological safety, and nutritional values) and, moreover, will degrade in composting conditions according to the standard UNE-EN 13432.
