Manufacturing method for easy-to-tear opening of soft packaging bag

The invention discloses a manufacturing method for an easy-to-tear opening of a soft packaging bag. The method comprises the following steps of manufacturing a packaging bag film, cutting the packaging bag film, slitting the packaging bag film, folding the packaging bag film, hot pressing the packaging bag film and sealing the packaging bag and the like. According to the manufacturing method for the easy-to-tear opening of the soft packaging bag, cutting process is carried out firstly, then slitting, folding, hot pressing and sealing processes are carried out after the cutting process is finished, so that a packaging bag with double-easy-to-tear openings is formed; the double-easy-to-tear openings manufacturing process and the required equipment structure are simplified, and the productionefficiency of the packaging bag with double-easy-to-tear openings is greatly improved; an anti-counterfeiting packaging bag film is adopted for the packaging bag film, so that the correlation betweentwo two-dimensional code
