Soft film ceiling is a modern and versatile interior decoration material that has gained significant popularity in recent years. Originating from Switzerland in the 19th century, it was further developed by a French inventor named Farmland Scherrer in 1967. He refined the technology and successfully introduced it to the interior design markets in Europe and the Americas. The material made its way to China in 1995 and initially found its place in high-end commercial spaces, particularly in coastal cities that were at the forefront of the reform and opening-up movement. Over time, its use has expanded beyond luxury settings, becoming a preferred choice for both residential and commercial interiors due to its aesthetic appeal, flexibility, and ease of installation. Today, soft film ceilings are widely used in offices, retail stores, and public spaces, offering a sleek and contemporary look while providing excellent acoustic performance and lighting integration.
