Latest Patents

One of Xiujun Li's latest patents is a laminating film resistant to discoloration caused by cooking. This innovative 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 film-laminated metal sheet exhibits excellent resistance to discoloration caused by cooking and is particularly useful for metal containers in food and beverage packaging that require high-temperature sterilization.

Another notable patent is for a high-strength multiphase tinned steel raw plate. This invention outlines the mass percentages of various components, including carbon, manganese, aluminum, and others, which contribute to the plate's high strength and better elongation. The tinned raw plate's structure includes ferrite grains, pearlite, martensite, and cementite particles, making it suitable for producing can bodies, can bottoms, easy-open ends, and twist-off caps for three-piece cans that demand higher strength and elongation.
