Shijiazhuang Shenwei Pharmaceutical Packaging Co., Ltd. developed and produced special plastic bottles, which were exported to Malaysia for the first time. It is reported that these products use Shijiazhuang Shenwei company's unique "photochromic" and "temperature-induced discoloration" patent anti-counterfeiting technology.
"Tempered color change" and "photochromic" are the original patented anti-counterfeiting technology of Shijiazhuang Shenwei Packaging Company. If plastic packaging products using the â€œTemperature Distortionâ€ technology are put into hot water, the bottles will quickly change color, and will quickly return to their original color after removal. Plastic bottles with "photochromic" technology can be exposed to light to achieve the same effect. Both of these anti-counterfeit technologies belong to the international initiative. Consumers can easily identify the authenticity of the product and make counterfeit products have nowhere to hide. These two technologies can be widely used for the packaging of solid and liquid products such as pharmaceuticals, cosmetics, and foods.
