The increased mechanical strength of the graphene zipper bags allows light weighting of the plastic, reducing the film thickness from 90µm to 60µm per bag.\n \n \n \n \n \n Food packaging primarily acts as a barrier to moisture and gases (including contaminants) that ordinarily lead to a reduction in the shelf-life of food.\n \n \n \n \n \n The new graphene-enhanced food storage bags keep the food fresher for longer thanks to the anti-bacterial, UV and barrier properties of functionalised graphene, resulting in less food waste. The graphene-composites polymer bags demonstrated their own oxygen blocking effect keeping food such as bread, cake and rice containing carbohydrates fresher for longer compared to non-graphene bags.\n \n \n \n \n \n Plastic packaging is necessary to maintain the shelf life of fresh food items, reducing food waste by spoilage before use. By ensuring barrier performance is delivered in products that can be recycled or composted, there is the potential for a more sustainable approach to the challenges often faced by produci...
