Nanotechnology applications for food contact materials

NanoWerk.com - Thu, 09/20/2018 - 12:45
Nanomaterials can improve the properties of food contact materials. Innovations of this kind are of particular interest for food packaging made out of plastic materials. The purpose of their use is to improve food storage and so to guarantee both freshness and quality. A further goal is to improve the technical properties of materials in order to make them sturdier more resistant to abrasion, and easier to process. With regard to environmental protection, little is known at present about the specific behavior of nanomaterials and composites during waste treatment processes.
