Shuangxing New Material Patent Covers Composite Aluminum Foil Film with Bond-Then-Roll Process
- Shuangxing New Material secured an invention patent for “A Composite Aluminum Foil Film and Its Preparation Method” (CN202311768687.9), authorized on August 7, 2026.
- The composite aluminum foil film uses a substrate layer with metal aluminum foil adhered to both faces, and the foil is roll-stretched from a first thickness of 5–15 μm to a second thickness of 3–8 μm.
- Its preparation method first adhesively bonds and laminates first-thickness metal aluminum foil to the substrate layer, then roll-stretches it to the second thickness, so no further lamination operation is needed afterward.
- Evenly distributed holes are present on both the metal aluminum foil and the rolling protective film, with the rolling protective film attached to the outer side of the metal aluminum foil.
According to disclosures from Tianyancha APP, Shuangxing New Material has added a new invention patent authorization. The granted patent is titled “A Composite Aluminum Foil Film and Its Preparation Method,” with application number CN202311768687.9 and an authorization date of August 7, 2026.
Per the patent abstract, the composite aluminum foil film comprises a substrate layer, with metal aluminum foil adhered to both faces of the substrate. The metal aluminum foil is produced by roll-stretching first-thickness metal aluminum foil of 5–15 μm on both sides of the substrate layer into a second thickness of 3–8 μm. A rolling protective film is attached to the outer side of the metal aluminum foil, and corresponding holes are evenly distributed on both the metal aluminum foil and the rolling protective film. The patent also covers a preparation method for the composite aluminum foil film. In this process, first-thickness metal aluminum foil serves as the starting raw material; it is first adhesively bonded and laminated to the substrate layer, then roll-stretched to the second thickness, so no further lamination operation is needed afterward.
