What material is Window Clings made of?

Clear Window Clings are printed on a durable 8mil clear, glossy film. That material is what gives the cling its see-through look and lets it sit flush against glass without any adhesive.

• Thickness: 8mil, thick enough to handle and reposition without curling or tearing.
• Finish: clear and glossy, so colors and backgrounds read cleanly on glass.
• Backer: a paper backing sheet protects the face until you install it. Peel it off right before application.
• How it holds: the cling grips smooth glass by surface contact rather than glue, so it is easy to remove or reposition with no sticky residue left behind.
