Huicong plastic: Recently, Shijiazhuang Shenwei pharmaceutical packaging Co., Ltd. applied two patents independently developed to prevent the degradation of PHB, which is a special color plastic packaging bottle developed and produced by Jinan gold assay digital display impact tester with surface corrosion degradation technology, and the first batch of it was exported to Malaysia
it is reported that these two original patents add new experimental methods for software self-upgrading or require manufacturers to provide new versions of software anti-counterfeiting technologies, namely photochromic and thermochromic technologies. If plastic packaging products with thermochromic technology are put into hot water, the color of the packaging bottle will change rapidly, and the original color will be restored soon after taking it out. Plastic bottles with photochromic technology can achieve the same effect when exposed to light. These two anti-counterfeiting technologies are international initiatives. Consumers can easily identify the authenticity of products, so that counterfeit products have nowhere to hide. These two technologies can be widely used in the packaging of solid and liquid products such as drugs, cosmetics and food
