使い心地と高気密性に配慮した広口耐油性容器の開発

摘要

今回，ポリオレフィン樹脂とポリエステル樹脂の積層構造容器を新開発し，耐油性，高気密性といった処方性能を活かせる容器性能に加え，使いやすく環境性に優れた容器設計を実現した。これからも消費者視点に立ち，使い勝手に優れ，サステナブル社会に貢献できるような容器開発を続けていきたいと考えている。%New sheet type makeup remover contains mineral oil. The mineral oil is key content for cleansing ability and comfort usability, however, it makes polyolefin (PE, PP) swell. The new oil resistant container consists of tub and lid. The container applies the multilayer structure made from polyester and polyolefin. Inner layer is polyester for oil resistant by vacuum molding. Outer layer is polyolefin for easy molding by injection molding. Lid is designed to place movable cavity which can adjust airtightness between tub and lid parts. The multi-layer structure achieves oil resistant, easy molding, usability and airtightness at the same time.
