INDUSTRIAL BAG CLOSING EQUIPMENT
Compare integrated lines, heat sealers, tying machines, folding units and sewing heads using the bag structure and required finished closure—not a model number alone.
Choose by bag construction, closure sequence, bag-top width, material, required output and finished appearance. A PE liner may need heat sealing before the outer woven or paper bag is folded, labelled, sewn or tape-bound. Final suitability should be confirmed with a real bag sample.

Compare the machines by closing process and reference specifications. Confirm the final configuration with your bag sample and production requirements.
Combine several operations into a continuous downstream packaging process.
An integrated line that levels the bag top, heat-seals the PE liner, applies hot-melt tape and sews the outer bag in one continuous process.
Four heating-block groups seal the inner PE liner; pressure rollers, bag-top folding and sewing then complete the woven outer bag.
A continuous bag-closing configuration for trimming, sewing and applying a hot-melt tape finish to supported multi-layer bags.
Coordinates bag-top folding, label feeding and sewing for continuous lines that require a label to be inserted into the closure seam.
Automatically folds and sews paper or woven bag tops and can be configured with selected GK, DS, GP4900 or ZB4907 units.
A conveyor-mounted sewing unit for continuous bag closing with adjustable operating height, variable-speed conveying and automatic thread cutting.
A compact clamping, feeding and sewing assembly with adjustable machine, traction and gripper speeds for line integration.
Close the inner liner or tie the bag neck before the next operation.
Continuously heat-seals PE bags, aluminium-foil bags and inner liners, with adjustable sealing height for automated packaging lines.
Automatically ties the neck of large plastic, woven and mesh bags and can be integrated into a continuous packaging line.
Prepare a consistent paper or woven bag top before sewing.
A mechanical bag-top folder designed to pair with selected sewing heads for paper, woven, jute and cloth bags containing powders or granules.
A chain-type folding unit for woven bag tops, designed for adjustable line speed and pairing with compatible automatic sewing heads.
Select the stitch, needle configuration, feed and cutting method for the bag.
A single-needle, two-thread chain-stitch head with bag counting, jog sewing and an electro-pneumatic thread-chain cutter.
A twin-needle, four-thread chain-stitch head designed for a denser closure, with an electro-pneumatic chain or paper-tape cutter.
A chain-stitch sewing head with automatic oil-bath and manual lubrication plus a cylinder-driven cutter for thread chain or paper tape.
A roller-feed continuous sewing head for automated lines, using sealed upper-shaft and looper-drive assemblies and automatic cutting.
Published specifications are for reference. Confirm the offered configuration using your bag sample before ordering.
ANSWER-FIRST SELECTION
A clear decision path connects each bag-closing requirement with the relevant equipment family.
Heat seal first
XPE-3 or an integrated line →Fold and sew
GP/ZB folder + GK/DS head →Fold, feed label, sew
Automatic label sewing machine →Trim, tape-bind and sew
KS-14 or KS-242D →TECHNICAL FAQ
Yes. BZR-3 and selected integrated configurations combine inner-liner heat sealing with folding and sewing of the outer bag. The exact film, bag size and required output still require a sample test.
A single-needle head produces one chain-stitch seam. A twin-needle, four-thread head produces two stitch lines for a denser closure. The correct choice depends on bag construction and the required finished seam.
Heat sealers, tying machines, folding units and automatic sewing assemblies can be configured for continuous lines. Confirm conveyor height, direction, speed, voltage and the control interface for your project.
Provide bag photos or samples, material and layers, bag width, product inside, bags per hour, required closure, voltage and frequency, destination country and line layout.
No. Specifications are reference values for the named machine. Output and closure quality depend on the bag, material, product, upstream feed and final configuration.
