WATERTIGHT FILM

摘要

PURPOSE:To provide a watertight film which is free from a fear of contaminating a carpet and floor even if insulation properties and watertightness are favorable and weight is loaded. CONSTITUTION:The title film is constituted of watertight adhesive layer 2 to secure watertightness and a supporting film layer 1 stuck firm to the fringe of the watertight adhesive layer 2 projecting from the fringe. Since an adhesive layer having a fixed flow index is formed and a projecting part is provided on the circumference of the watertight adhesive layer 2, the title film has an advantage that favorable watertightness and insulation properties can be displayed.
