MUNICH, Germany, Feb. 23, 2017 (Press Release) -The main objective of this project was to develop a packaging concept for regional fruit and vegetable products based on materials referred to as permselective packaging materials, i.e. packaging materials with selective gas permeability for oxygen and carbon dioxide. In the case of the packaging materials used, particular focus was placed on functionality and ecologically beneficial packaging materials. Both synthetic and bio-based materials were taken into account.

The materials used for the test packages exhibited ecological advantages such as recyclability (carton board trays), biodegradability (carton board and PLA trays) and potential reuse (synthetic polymers for lid films). They were also in accordance with current legislation for food contact materials. Costs estimations showed comparable material costs between the investigated test packages and commercially available packaging solutions.

It was successfully demonstrated within the project that the EMAP concept works and suitable materials are available. But before the findings of this project could be transferred into commercial products further improvements have to be made.

The development of concepts for packaging with selective permeable materials was targeting several market sectors. Based on the results of the project paper and plastic packaging manufacturers and suppliers will be able to propose new, improved packaging materials to their customers. Food producers will get better packaging and therefore improve the shelf-life of their products and thus their cost-effectiveness. Chemical manufacturers will have new uses for their materials, and finally food retailers will reduce waste by marketing products with a better shelf-life.
