MuYunSign Unveils Innovative Vinyl Window Film to Enhance Comfort and Protection.

Shanghai, China – Nov. 1st, 2025 – Shanghai MuYunSign New Material Co., Ltd., a global supplier in innovative

home and office solutions, today announced the launch of its premium line of Vinyl Window Film. This advanced product

is designed to provide homeowners and businesses with an affordable and effective way to improve energy efficiency, enhance

privacy, and protect against harmful UV rays.

Unlike traditional solutions, MuYunSign's vinyl film is a durable, optically clear, and easy-to-apply layer that acts as an invisible

shield for windows. It offers a multifaceted solution to common problems without the need for expensive window replacement.

Key benefits of the new Vinyl Window Film include:

· Significant Energy Savings: The film provides an insulating barrier, reducing heat loss in the winter and blocking solar heat gain

in the summer. This can lead to lower heating and cooling costs throughout the year.
· 99% UV Protection: By blocking the vast majority of ultraviolet rays, the film helps prevent fading and damage to valuable interior

furnishings, including carpets, artwork, and furniture.
· Enhanced Safety and Security: The film strengthens the window pane, holding shattered glass in place in the event of impact.

This helps protect against injuries from broken glass and can deter forced entry.
· Increased Privacy: Available in a range of tints and opacities, the film allows occupants to enjoy natural light while reducing visibility from the outside.

"Our mission has always been to provide smart, simple solutions that make a tangible difference in our customers' lives," said Miss Qin at MuYunSign.

"This new vinyl window film is a perfect example. It's a single upgrade that saves money, protects belongings, and increases comfort and safety.

It’s an investment that pays for itself."

The vinyl window film is easy to install by professionals and is backed by a 1-year warranty, ensuring long-lasting performance.
