Core Advantages
1.Seamless Production Line Connection
After folding and rewinding, the double-layer film can be directly used for heat sealing on bag making machines. No additional debugging is required, which greatly improves the continuity and overall efficiency of the whole production line.2.High Automation & Labor Saving
The whole process including unwinding, folding and rewinding runs automatically. Only one operator is needed for monitoring, which eliminates heavy manual folding work and effectively cuts labor costs.3.Stable Constant Tension Control
The rewinding system adopts constant tension regulation. Combined with magnetic powder clutch or servo system, it adjusts rewinding force in real time to prevent film deformation caused by uneven tension.4.Expandable Functional Modules
Optional punching and slitting modules are available. The machine can complete slitting and punching while folding and rewinding, expanding its application scope to meet diversified production demands.5.Neat Finished Rolls & Space Saving
The folded film rolls feature flat edges and uniform diameter. They are tidy to stack and save storage space for workshops.Packaging And Delivery
The machine is packed with standard export wooden cases and stretch film, featuring excellent anti-collision, moisture-proof and dust-proof performance. We support sea freight, air freight and combined logistics, and deliver goods as scheduled.
