China Wholesale Ketchup Sachet Packaging Machine Factory & Exporters

Our machines utilize positive-displacement linear servo-driven piston pumps or high-precision rotary lobe pumps specifically engineered for viscous, non-Newtonian liquids. The stroke displacement of the piston is regulated down to hundredths of a millimeter via the HMI interface. Furthermore, heated product hoppers with mechanical agitators keep the sauce at a consistent temperature and viscosity, ensuring filling accuracy within ±0.5%.

We integrate proprietary anti-drip cut-off nozzles equipped with positive pneumatic blow-back or vacuum suck-back functions. Additionally, the filling cycle is electronically synchronized with the vertical film pull movement, allowing the nozzle to lower deep into the pouch during dosing and retract cleanly before the horizontal heat-sealing jaws engage.

Yes. Our sachet machinery features tool-less, quick-change vertical forming shoulders and adjustable bag length parameters via the touchscreen. While sachet width is fixed by the former size, pouch length can be modified instantaneously. For switching between low-viscosity soy sauce and high-viscosity mayonnaise, pump parameters and agitation speed can be saved as pre-configured recipes in the PLC memory.

All machines manufactured in our facility carry full European CE Certification under the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. The factory operates under ISO 9001:2015 quality management systems. All food-contact parts are supplied with material traceability documentation confirming compliance with FDA 21 CFR and EU 1935/2004 food-grade stainless steel standards.

Standard single-lane liquid sachet packing machines are manufactured within 25 to 30 business days. Multi-lane high-speed customized production lines require 40 to 55 days. All equipment is backed by a 2-Year Full Manufacturer Warranty covering mechanical components and electronic controllers, supported by remote video assistance and express spare parts dispatch.
