[origin: EP3750827A1] The present disclosure discloses an inflatable bag with a protective base, which is formed by stacking two outer films and two inner films located inside the outer films and by means of heat sealing and inflating, which includes two opposite side walls, each of which comprises a plurality of side wall air columns; and a bottom wall, which is located between the side walls and connected to bottom portions thereof. The bottom wall includes a plurality of bottom air columns, wherein a first bottom air column section, a protective air column section and a second bottom air column section are delimited in sequence in each of the bottom air columns, the first bottom air column sections are connected to the second bottom air column sections by forming first heat sealing nodes to bond the outer films and the inner films together, and at least one second heat sealing node is formed on each of the protective air columns to bond the outer films and the inner films together, so that the protective air column sections are folded to form a protective base.
