Is Cling vinyl film suitable for outdoor applications? No! Alt-hough it may be suitable for some shorter term outdoor projects, it does not tolerate high temperatures or exposure to excessive UV light. Long term exposure to the elements can cause the material to yellow, become brittle, or turn hazy. The best products we stock for outdoor use are HDPE and polypropylene. However, it is possible for us to custom source formations of vinyl that are designed to last outdoors for a specific period of time. Many outdoor sign materials are made out of vinyl designed to last five years or more: Please contact us for more information.
