Plastic Drawstring Trash Bag Machine

The Plastic Drawstring Trash Bag Machine is a fully automatic integrated production equipment specially developed for manufacturing roll-type drawstring trash bags. It supports LDPE, HDPE and biodegradable plastic film raw materials, finishing film conveying, rope threading, heat sealing, perforation, folding and rolling in one continuous procedure. Adopting servo drive and PLC touch screen control, the equipment runs stably, with accurate sealing and neat finished bags, suitable for household, catering and commercial garbage bag mass production.

Operators can simply set bag width, length and drawstring position on the human-machine interface to produce different specifications of drawstring trash bags. Optional automatic roll changing device effectively reduces downtime, lowers material waste and greatly improves overall production efficiency.
Our factory optimizes the mechanical structure of the Plastic Drawstring Trash Bag Machine, strengthening the heat-sealing component to avoid weak sealing and string falling problems. With reliable quality, easy maintenance and long service life, this machine is the ideal core equipment for plastic packaging factories to produce popular drawstring trash bags.
