Shuangxing New Material Obtains Patent for a Composite Aluminum Foil Film and Its Preparation Method
- Shuangxing New Material has been granted an invention patent titled “A Composite Aluminum Foil Film and Its Preparation Method,” with application number CN202311768687.9 and grant date August 7, 2026.
- The composite aluminum foil film consists of a substrate layer and metal aluminum foil adhered to both sides of the substrate layer.
- The metal aluminum foil is formed by rolling and stretching 5–15 μm first-thickness aluminum foil on both sides into 3–8 μm second-thickness aluminum foil.
- A rolling protective film is attached to the outer side of the metal aluminum foil, and holes at corresponding positions are evenly distributed on both the metal aluminum foil and the rolling protective film.
- The preparation method uses first-thickness metal aluminum foil as the initial raw material; after bonding and laminating it with the substrate layer, it is rolled and stretched to the second thickness, with no further lamination operation required.
According to Tianyancha APP, Shuangxing New Material has newly obtained an invention patent authorization, titled "A Composite Aluminum Foil Film and Its Preparation Method," with patent application number CN202311768687.9 and authorization date August 7, 2026.
Patent abstract: The invention discloses a composite aluminum foil film, composed of a substrate layer and metal aluminum foil adhered to both sides of the substrate layer, wherein the metal aluminum foil is formed by rolling and stretching metal aluminum foil of a first thickness of 5~15μm on both sides of the substrate layer into metal aluminum foil of a second thickness of 3~8μm, a layer of rolling protective film is attached to the outer side of the metal aluminum foil, and holes at corresponding positions are evenly distributed on the metal aluminum foil and the rolling protective film. The invention also discloses a method for preparing the above composite aluminum foil film. The composite aluminum foil film of the invention uses metal aluminum foil of the first thickness as the initial raw material, and after bonding and laminating it with the substrate layer, performs a rolling and stretching operation to convert it into the second thickness, after which no further lamination operation is required.

Recently, the Tropical Crop Origin Processing Team of the Institute of Processing, Chinese Academy of Tropical Agricultural Sciences (CATAS) systematically elucidated the regulatory mechanism of metal ions on the structure, properties and food preservation functions of spent coffee grounds-based films, providing new ideas for the high-value utilization of spent coffee grounds and the development of degradable food packaging materials. As the main by-product of the coffee industry, spent coffee grounds are produced in huge quantities globally each year, but most are landfilled as waste, which easily causes environmental problems such as water pollution and methane emissions. It is worth noting that,
