The present invention relates to a membrane for forming a sealing layer in a storage tank (10) capable of storing liquefied gas, and includes a first extension part (31) extending in one direction, and a second extension part (32) extending in a direction different from the first extension part (31). According to the present invention, the extension length of the first extension part (31) is different from the extension length of the second extension part (32), so that an asymmetric membrane (30) in which the first extension part (31) and the second extension part (32) are asymmetric may be provided. An objective of the present invention is to provide the asymmetrical membrane capable of simplifying the arrangement of the membranes forming a sealing layer. 액화가스를 저장할 수 있는 저장탱크(10)에 밀봉층을 형성하기 위한 멤브레인으로서, 일방향으로 연장되는 제1 연장부(31)와, 상기 제1 연장부(31)와는 상이한 방향으로 연장되는 제2 연장부(32)를 포함하며, 상기 제1 연장부(31)의 연장 길이는 상기 제2 연장부(32)의 연장 길이와 상이하여, 상기 제1 연장부(31)와 상기 제2 연장부(32)는 비대칭 형상을 이루는 비대칭형 멤브레인(30)이 제공될 수 있다.
