Our Building Shrink Wrap is a Canadian-made, high-strength polyethylene film that shrinks when heat is applied. The heated plastic film shrinks to create a perfect fit around any object, framework, or engineered scaffolding. Our 9mil Wrap has UV inhibitors built-in to protect against degradation from the sun’s UV rays.
