ABSTRACT:
A metallized high specular gloss polyethylene plexifilamentary film-fibril sheet with very low emissivity is made by a process of calendering a polyethylene film-fibril sheet between a smooth metal roll and a soft, resilient roll to form a sheet of high specular gloss, followed by vacuum metallizaction of the smooth high specular gloss surface. Such metallized sheets are useful as radiant barriers or roof liners for energy savings purposes.
