Strippable film is a clear pressure sensitive polyethylene plastic film that is applied to some roofing products to assist in protecting the surface from damage and scratching during forming, transportation, handling, storage, and erection.
Strippable film is designed to provide some protection to the product before and during installation on the building. It is not designed to protect against corrosion, humidity, or chemicals.
Strippable film must be removed before prolonged exposure to sunlight, as that may make it extremely difficult to remove. Prolonged exposure and wet conditions can also cause the film adhesive to whiten and breakdown, leaving residue on the painted surface when the film is removed. Once removed from the sheet for installation, strippable film must be collected and removed from the site.
Product with film applied must be stored at temperatures of less than 50°C and out of direct sunlight to avoid prolonged UV exposure.
The product needs to be kept dry to prevent moisture ingress between the film and the painted surface. In the long term moisture ingress may cause issues to the painted surface; and in the shorter term cause the film adhesive to whiten and breakdown, leaving residue on the painted surface when the film is removed.
