Due to the special nature of nanomaterials and structures on its surface, the material has generally difficult to obtain excellent performance, by means of conventional coating technology, adding the nano materials, can get nano-composite compund system coatings, this could modify the traditional coating capabilities. For example, special wear-resistant transparent coating material without pollution is made from silicon-based nano-ceramic, painted on glass, plastic and other objects, with dirt, dust, scratch, wear, fire and other functions, can be used in food contact surfaces coated packaging material.
Metal particles having infrared absorbing characteristics, and have the large surface area, high surface activity, are sensitive to the surrounding environment(temperature, humidity, light), when the characteristics of these nano-particles has added packing material, or to form a coating, the varnish coating after the surface of the packaging material of cloth, or by the temperature, humidity, light, or the product to be identified, so as to achieve the purpose of security. Nano coating with color packaging material security, physical and chemical effects of anti-counterfeiting and other functions.
Application of Nano packaging materials.
Nano-technology not only widely used in chemical fiber, plastics, rubber, ceramics, paints, coatings, paper, etc., to improve product quality and achieve some special properties of the product, while in aseptic packaging, antimicrobial packaging, deodorant packaging, high barrier packaging also be widely applied. With the advent of packaging development, increasing demand for packaging for special functions, such as anti -static packaging, explosion-proof packaging, anti-electromagnetic packaging, packaging camouflage, stealth packaging, dangerous goods packaging, anti- radar and other new packaging requirements, to promote the nano- packaging development of technology. Because nanotechnology is emerging in the last 10 years, a comprehensive science and technology, the study will address all areas of modern high-tech multi-directional. Such as nano- physics, nano- biology, nano- chemistry, nano- electronics and nano- processing technology, nanotechnology research in the process of packaging materials but also the development of nano- packaging applications are subject to production scale nano-composite material costs, packaging multiple factors influence the use and packaging materials, etc., but the special properties of nano- packaging materials, has broad prospects for development in saving material resources to meet the functional requirements of special packaging and other aspects.
