Industrial bag-mouth closing equipment · Made in China
One closing process rarely fits every bag. Zhongda combines heat sealing, folding, sewing, label insertion, trimming and tape binding around your package and production target.
Illustrated configuration: KS-242D. Final configuration depends on bag tests.
01 — Product families
Choose one machine family or connect both as a downstream packaging line.
Configure the bag mouth around the liner, outer bag and required finish.

The website guides buyers by process, then connects each requirement to a machine configuration.
METHOD 01
Continuous controlled heat closes PE inner liners, plastic films and compatible composite bags. Cooling and conveyor requirements are configured around the bag material and line speed.

04 — Applications
Start with the customer’s actual bag to determine whether the liner needs sealing, how the outer bag should be prepared, and which final closure is appropriate.

Images are unbranded application illustrations. Final machine configuration must be confirmed using the customer’s actual bag, material, dimensions, product, and required output.
05 — Buyer evidence
The final website will use verified factory materials instead of invented export numbers, certifications or client logos.
06 — Technical FAQ
Start with the bag structure, bag width, material inside, required output, closure sample and local voltage. Zhongda then maps the required steps—heat sealing, folding, sewing, label insertion, trimming or tape binding—to a configuration.
Yes. Combined configurations are intended for this process. Suitability depends on the exact film structure, thickness, bag dimensions and required speed, so a sample should be tested before final confirmation.
Options include GK35-6A, GK35-8A, DS-9C and DS-11. Confirm the sewing head and line configuration against your bag material and required closure.
Please provide bag photos or samples, bag material and dimensions, product inside, bags per hour, closure method, voltage and frequency, destination country and any preferred options.
