ULTRAVIOLET LIGHT-BLOCKING FILM AND ULTRAVIOLET LIGHT-BLOCKING CONTAINER

摘要

PURPOSE:To provide the subject film and the subject container using this film. CONSTITUTION:This virtually transparent cylindrical film having thermal shrinkability can be obtained by incorporating a synthetic resin material with 1.0-70.0wt.% of ultrafine zinc oxide powder 0.005-0.1mum in particle diameter. The objective container can be obtained by cladding the cylindrical film on the outer peripheral surface of a container body made of a plastic or glass followed by heating and shrinking the film to effect film adhesion of the film to the container surface to form an ultraviolet light absorbing film.
