Product Details

This product is designed for kraft paper bags with PE inner linings and a folded outer edge. The closure process heat seals the PE liner first, then folds the bag mouth along the sealing line and seals the folded edge using hot-melt paper. The corresponding GKS-324D system completes these stages automatically and uses a specially designed clamping conveyor chain to transfer the finished bag after sealing. The catalogue describes the complete sealing process as automatic without manual intervention. The product is therefore differentiated from the stitched paper-bag systems because its outer closure is based on folding and hot-melt paper sealing rather than conventional outer-bag stitching.

8 Features

The system first heat seals the PE inner liner before processing the outer kraft paper bag.

The bag mouth is folded along the inner sealing line to form the folded outer edge.

Hot-melt paper is used to seal the folded outer edge.

The entire closure sequence is performed automatically without manual intervention.

A clamping conveyor chain transfers the sealed bag after the closure process.

The machine is designed for kraft paper bags with PE inner lining and folded edges.

The sealing height can be adjusted within the specified machine range.

The system combines inner heat sealing, folding and hot-melt paper sealing in one integrated process.
