[0022] By setting up the pretreatment mechanism package, when in use, first the fixed plates are set on both sides of the feeder, and then cold air is injected into the pretreatment cooling hood through the micro-cooling fan. At this time, the polypropylene film passes through the pretreatment cooling hood, and the pretreatment cooling hood pretreats both sides of the polypropylene film to harden both sides of the polypropylene film to avoid indentations caused during limiting. Then the rotating wheel can enable the polypropylene film to pass through the pretreatment cooling hood better.
