MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617061935 A) filed by Prime Polymer Co. , Ltd. on May 15, 2026, for Laminated Film, Unstretched Film, Polypropylene-Based Polymer Composition, And Propylene-Based Polymer.
Inventors include Murakami Tomoya; Mizukawa Tomoaki; and Takai Nagi.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: Disclosed are: a polypropylene-based polymer composition which contains 85-95 mass% of a resin A and 5-15 mass% of a resin B (provided that the total amount of the resin A and the resin B is 100 mass%); a laminated film which includes an unstretched film that is formed from the polymer composition and a layer that is formed by vapor-depositing an inorganic oxide; and a propylene-based polymer which contains the resin B. Resin A: A resin which has a melting point of 120-170 °C and a limiting viscosity (?) of more than 1.5 dl/g but not more than 5.0 dl/g. Resin B: A resin which contains 10-40 mass% of a propylene-based polymer (b1) that has a limiting viscosity (?) in the range of 10-12 dl/g and 60-90 mass% of a propylene-based polymer (b2) that has a limiting viscosity (?) in the range of more than 1.5 dl/g but not more than 2.5 dl/g (provided that the total amount of the polymer (b1) and the polymer (b2) is 100 mass%).
