The SVARNISH project objective is the development of a varnish with antimicrobial, oxygen and water vapor barrier properties as well as improved physic-mechanical properties, to be used in food industry.The SVARNISH project aims to overcome the flexible packaging limitations related with the traditional food plastic materials, competitive costs, the chemical properties (antimicrobial, oxygen and water vapor), physic-mechanical properties (simplifying the multilayer structures as well as improving the simple ones), environmental and sustainable development. We aim to reduce the price of the food packaging around 20% and reduce waste material by 8-10%, decreasing the time process manufacturing by 50% and reducing the energy consumption by the same 50% as well as reduce food waste by 50% and 85% of the films used for food packaging will therefore become recyclable.The food industry spends approximately $84 billion a year on food packaging and processing. On the total food cost, approximately 8% of the price to the consumer is spent on food packaging and processing. Therefore, it is clearly beneficial to both the consumer and the industry to use food packaging strategies that are both functional and cost effective. A number of broad drivers in the packaging sector are shaping innovation in product and process development: reduction in materials usage, lightweighting, increase the barrier properties requirement, increase
production speed, increase product shelf life, improve environmental balance, recyclability or biodegradability. Plastic packaging supposes a great environmental problem, due to extensive uses, difficulty to be recycled and their high volume/weight ratio. The manufacturing process applied to the flexible packaging conversion accounts for over 43% of the environmental impact of the total printing industry, due to plastic residues generated and VOCs emitted during manufacturing process: inks, varnishes and other additives. The impact on our environment can therefore be minimized by improving packaging structures, selecting materials and subsequently established regulatory guidelines.environmentThe structure of SVARNISH consortium has been selected through a logical process from “the raw material needed to improve the varnish to the final printing process”, all supply chain is then represented.To sum up, we believe that SVARNISH could become a solution which will improve packaging structures in an environmental and in a cost efficient way by reducing the structures, by the other hand will confer to packaging structures, barrier and improved physic-mechanical properties.
