Recently, Shijiazhuang Shenwei Pharmaceutical Packaging Co., Ltd. has developed two special patented anti-counterfeiting technologies developed to produce special plastic bottles. It is reported that these two original patented anti-counterfeiting technologies are "photochromic" and "temperature-induced discoloration" technologies, respectively. If you put plastic packaging products that use the “Temperature Discoloration†technology into hot water, the bottles will quickly change color, and will soon recover the original color after removal. The use of "photochromic" technology in plastic bottles placed under light irradiation, can achieve the same effect; these two anti-counterfeiting technologies are all international initiatives. These two technologies can be widely used for the packaging of solid and liquid products such as pharmaceuticals, cosmetics and foods. The first products of this technology have been exported to Malaysia.
