High Precision Drawstring Threading and Heat Sealing Machine

High Precision Drawstring Threading and Heat Sealing Machine This machine is used after the bag is made. It installs a cotton drawstring at the bag mouth and heat seals it. Materials: PE, TPU, EVA and similar plastic films. The bag edge must be heat-sealable. Not for cloth bags, non-woven bags or paper bags. Here's how it runs. Someone puts the bag in the holder. Machine feeds the cotton cord and lines it up along the bag mouth. The sealing bar drops down and seals the cord into the folded edge. Then the bag comes out, and the next one goes in. That's the whole cycle on the Drawstring Threading Heat Sealing Machine. Semi-auto. You load and unload by hand. The machine handles threading, positioning, and sealing. Speed? Depends on the bag and the person. Small bags go quick. Big bags take longer. Nothing surprising there. Cotton cord, remember. When the bar seals, the plastic around the cord melts and sticks. The cotton doesn't melt. After it cools, the cord is trapped in the sealed edge…
