Title: Innovations of Zhangwei Wang in Laminating Technology
Introduction
Zhangwei Wang is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of laminating technology, particularly in developing materials that enhance the durability and functionality of packaging solutions. With a total of 3 patents, his work focuses on creating innovative films and laminated materials that resist discoloration and improve product quality.
Latest Patents
Zhangwei Wang's latest patents include a laminating film resistant to discoloration caused by cooking. This film-laminated metal sheet is a blended polyester laminating film that comprises polyethylene terephthalate and polybutylene terephthalate. The film consists of three layers, with one surface layer containing SiO in a mass fraction of 1200-2000 ppm added by in-situ polymerization. The manufacturing process involves a three-layer coextrusion biaxial stretching method at temperatures between 240-275° C. This innovative film is particularly useful for metal containers used in food and beverage packaging that require high-temperature sterilization.
Another notable patent is for laminated steel having an extremely low interface bubble rate. This laminated steel features a substrate with a surface roughness of 0.15-0.25 μm, onto which a modified flexible polyester film is thermally laminated. The film is produced through copolymerization modification of ethylene terephthalate with a low-molecular-weight aliphatic polyester. The manufacturing method includes preheating the substrate, thermally laminating the film, and cooling and squeeze-drying the final product. This technology results in laminated steel with high product surface quality and excellent adhesion properties, making it suitable for deep-drawn containers.
