Packing Process
 
01/

Film Unwinding & Tension Control: Rollstock film is mounted onto the motorized unwinding shaft, passing through tension-control dancer arms to maintain constant web stability.

02/

Film Registration Tracking: The optical photoelectric sensor scans the printed eye-mark on the film web, feeding positional data back to the control system to keep print alignment exact.

03/

Pouch Forming: The flat film web passes over the stainless steel forming collar and folding tube, transforming into a continuous vertical tube shape.

04/

Vertical Fin Sealing: The vertical sealing bar applies heated pressure down the back overlap of the film tube to form a secure longitudinal seam.

05/

Volumetric or Gravimetric Dosing: The synchronized filling funnel discharges the pre-measured dose of powder, liquid, or granule directly into the formed film tube.

06/

Horizontal Sealing & Cross Cutting: Horizontal sealing jaws close to form the top seal of the current sachet and the bottom seal of the subsequent sachet simultaneously, while the internal cutting blade severs the individual pack.

 

 

Filling & Dosing Systems

Auger Screw Dosing Filler: Driven by high-torque stepper or servo motors with adjustable screw pitch, engineered for fine, cohesive, and non-free-flowing powders.

 

Volumetric Cup Dosing Mechanism: Telescopic volumetric cups with adjustable volume cavities, designed for free-flowing granular products.

 

Multi-Head Electronic Weigher: High-precision load cell weighing buckets combining microcomputer calculations for exact weight batching of irregular or fragile granules.

 

Piston Liquid Pump Dosing: Pneumatic or servo-driven positive displacement piston pumps equipped with anti-drip nozzles, suited for watery liquids, oils, and high-viscosity creams.

 

Peristaltic Pump Systems: Precision tube-squeeze liquid dosing units preventing product contact with mechanical pump internals, ideal for pharmaceutical liquids and chemical reagents.

FAQ

 

 

Q: What is the typical production lead time for an order?

A: Standard machine configurations require 20 to 30 business days from order confirmation and sample material receipt. Fully customized multi-lane or integrated lines require 45 to 60 business days.

Q: How are changeover times managed for different sachet sizes?

A: Format changeovers require swapping the forming collar tube assembly and adjusting jaw parameters via the PLC touchscreen, keeping total downtime under 30 minutes.

Q: What film materials are compatible with these machines?

A: The systems process heat-sealable laminated rollstocks, including PET/PE, BOPP/PE, paper/PE, aluminum foil laminates, and co-extruded polyethylene films ranging from 40 to 100 microns in thickness.

Q: What electrical power requirements must be prepared on-site?

A: Standard units operate on single-phase 220V or 3-phase 380V supplies. Custom voltage transformers can be integrated during manufacturing to match regional industrial grids.

Q: What after-sales technical support is provided?

A: Remote diagnostic support is available via video communication channels. Replacement mechanical and electrical components are dispatched directly from stock inventories, accompanied by engineering installation guides.
