PURPOSE:To intercept reflected laser beam at an about 100% laser intercepting rate, by intercepting reflected laser beam from a body, irradiated with laser beam, by a laminate film including an aluminum vapor-deposited layer. CONSTITUTION:On one side of a film of low-density polyethylene, high-density polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamide, polyester, etc., where aluminum can be vapor-deposited, aluminum is vapor-deposited to 100- 700Angstrom by the vacuum depositing method, thus forming a laminate film including the aluminum vapor-deposited layer. Reflected laser beam reflected by a body irradiated with laser beam is intercepted by said aluminum vapor-deposited laminate film. As the laminate film, an aluminum vapor-deposited plastic film having paper, nonwoven fabric, etc., laminated on both the sides is usable. |
