How does the packaging industry adopt the latest emerging technologies （6）?
3D printing is a growing trend in the packaging industry, allowing companies to build different prototypes and innovate their packaging lines in near real time. Brands often try packaging design, but this design is costly, time-consuming, and wasteful. 3D printing technology can alleviate these problems and promote personalized packaging, and the contribution to plastic waste is zero. This technology provides engineers and designers with greater design freedom so that they can produce high-quality products. Manufacturers also use additive manufacturing technology to manufacture prototypes of packaging mechanical parts, for example, by printing robotic arms for specific packaging lines. From packaging materials to product safety, certification and tracking, nanotechnology is used at all stages of the packaging supply chain. The use of nanoparticles mixed with polymer chains can enhance the barrier properties and tensile strength of packaging. It can also help brands and packaging companies to track and anti-counterfeiting. In addition, nanotechnology has had a huge impact on the food packaging industry by addressing food safety issues that people are increasingly concerned about. Nano-coating on the packaging surface can protect it from dirt, dust and stains. Finally, several types of nanosensors can be used to monitor food freshness and detect any chemical changes.
