Abstract

The invention provides a production method of a square-base self-supporting bag with an opening. The problem that organ sides are propped open easily is solved by drilling holes in lateral organ side; the problem that the existing self-supporting bags are not provided with lateral organ sides is solved through reversing and heat sealing of the self-supporting base. According to the production method, the loading volume of the square-base self-supporting bags with openings is bigger than that of those with the same specifications, and the produced square-base self-supporting bags have a stereoscopic and beautiful standing effect.
