FILM FOR TIRE INNER-LINER AND PREPARATION METHOD THEREOF, PNEUMATIC TIRE, AND PREPARATION METHOD OF PNEUMATIC TIRE

摘要

PURPOSE: A film for a tire innerliner is provided to have excellent and uniform physical properties in all directions when applied to a tire and to have excellent durability and fatigue resistance in manufacturing tire and vehicle-driving. CONSTITUTION: A film for a tire innerliner includes a substrate film which is elongated and aligned in a first direction and non-elongated in a second direction vertical to the first direction. The first direction is parallel to the axis direction of a tire molding drum. The strength ratio of the first direction to the second direction of the substrate film is 1.1:1-2:1. The film for the tire innerliner additionally includes an adhesive layer which is formed at least one side of the substrate film and includes a resorcinol-formalin-latex-based adhesive.
