The granted patent (Publication Number: US11919190B2) discloses a process for introducing perforations into a laminate, involving steps such as providing a laminate with a substrate layer and a silicone gel layer, using an ultrasonic welding device with perforating elements, applying ultrasonic energy to create perforations while deforming a layer, and keeping the deformed portions in contact with the silicone gel layer for at least 12 hours. The process aims to efficiently introduce perforations into the laminate while maintaining the integrity of the silicone gel layer.

The patent claims specify various aspects of the process, including the type of substrate layer (polymer), its thickness, the composition of the silicone gel layer, the softness/penetration depth of the silicone gel layer, the amount of silicone gel per square meter, the diameter of the perforations, and the material of the deformable layer. Additionally, the process involves a specific timeframe between joining the substrate layer with the silicone gel and applying ultrasonic energy. The process ensures the effective introduction of perforations into the laminate, catering to various parameters such as material properties and perforation size, ultimately enhancing the functionality of the laminate in specific applications. The patent also includes a step for removing the deformable layer after the specified contact time, indicating a comprehensive method for producing perforated laminates with silicone gel layers.
