M-type inflatable bag

Abstract

An M-type inflatable bag includes a bottom wall, two side walls, two protective walls and two connecting portions. The bottom wall includes a plurality of bottom gas columns. Each of the side walls includes a plurality of side gas columns. Each side wall is located on two opposite sides of the bottom wall. The side walls and the bottom wall are divided at a joint to form a receiving space and a limiting space. The protective walls include a plurality of protective gas columns, and the protective walls are separately located outside the side walls. The connecting portion includes a plurality of first heat sealing nodes adjacent to the side wall and a plurality of second heat sealing nodes adjacent to the bottom wall. When the side wall and the bottom wall are bent, a buffer bump is formed between a first virtual bending line and a second virtual bending line.
