Abstract
A buffer air column with a three-dimensional structure includes a first buffer portion and a second buffer portion. The first buffer portion includes a first air column, a first heat sealing section and a second heat sealing section. The second buffer portion includes a second air column, a first connection side, a second connection side and a corner area. One end of the corner area is connected to the first connection side, the other end is connected to the second connection side, and the corner area is used for abutting against a case body. A buffer slot is formed between the second air column and the first air column, and when an article abuts against the first air column, the first air column buffers and protects the article, and the buffer slot is compressed due to the pressure and assists in buffering and protecting the article.
