Shanghai Tangke|Patent for high-performance aluminum-plastic composite packaging ton bags
Shanghai Tangke New Materials Technology Co., Ltd. has recently submitted a patent application named 'A Type ofAluminum-Plastic Composite Packaging Ton Bag Material and Its Preparation Method' to the National Intellectual Property Administration, with publication number CN119773332A, and an application date of December 2024. This patent involves the processing technology of ton bag materials, aiming to meet the current market's demand for high-performance packaging materials. 
According to the patent abstract, the aluminum-plastic composite packaging ton bag material consists of several raw materials, specifically: 8-9 parts of PET film, 4.5-5.6 parts of aluminum foil, 10-11.4 parts of PA film, and 72-77 parts of PE film, where the PE film composition includes linear low-density polyethylene, metallocene polyethylene, TPU, and various other components. Through a thermal pressing process, these materials are layered and bonded together to form a ton bag with excellent performance, ensuring that the final product exhibits outstanding water resistance, moisture resistance, and anti-static properties.
The patent document states that this ton bag material can effectively block oxygen, has good thermal insulation, waterproof, and moisture-proof properties, and is not easily damaged even after repeated folding and rubbing, showcasing remarkable durability.
Shanghai Tangke New Materials Technology Co., Ltd. was established in 2006. The company focuses on the research and production of rubber and plastic products （Vacuum Sealer Bag、Laminated Film、Aluminum Plastic Composite Bag 、Ton Bag）,and has accumulated abundant results in patents and trademarks in recent years,holding 85 patents and 11 trademark registrations.
