Does Cling vinyl film have good insulation properties?

Does Cling PVC vinyl film have good insulation properties? Yes. Cling PVC film is a vinyl polymer. It’s not as resistant to high temperatures as polyester films, but vinyl excels in low temperature applications. In the case of Cling, it is possible that extreme low temperatures could cause the film to loose its “tack” and become less sticky. But that should not affect its insulation properties.
