Engineering Excellence in Edible Oil Portion Packaging
The global demand for single-serve edible oil sachets (ranging from 5ml to 100ml) is experiencing an unprecedented surge across commercial catering, ready-to-eat meal kit manufacturing, airline catering, emergency food supplies, and fast-moving retail packets. However, dosing liquid fats—such as palm oil, extra virgin olive oil, soybean oil, sesame oil, and mustard oil—presents complex mechanical challenges due to variable fluid viscosity, temperature sensitivity, stringing, and seal-contamination risks. Selecting a top-tier Chinese manufacturer requires rigorous evaluation of pump kinematics, thermal sealing accuracy, nitrogen flushing integrity, and sanitary metallurgy.
Dosing Architectures for Liquid Fat Packaging
Comparing volumetric piston pumps, rotary gear pumps, and peristaltic metering systems for leak-free, high-speed sachet creation.
Servo-Driven Volumetric Piston Pumps
Utilizing high-torque Kollmorgen or Panasonic servo drives mated to ground 316L stainless steel cylinders, servo pistons provide non-pulsating volumetric dosing for oils with viscosities between 20 to 150 cSt. The digital stroke setting allows micro-adjustments in increments of 0.05ml, preventing product giveaway while handling temperature-induced density changes.
Vacuum Suction-Back Anti-Drip Nozzles
Oil contamination on horizontal seal jaws is the leading cause of channel leaks and pouch rejects. Our proprietary pneumatic shut-off nozzles incorporate an active vacuum suck-back sequence immediately following liquid discharge. This instantly eliminates trailing droplets, maintaining pristine, oil-free film contact surfaces for airtight heat seals.
Gas-Tight Nitrogen (N₂) Purging Systems
Edible oils degrade rapidly when exposed to atmospheric oxygen, causing lipid oxidation and rancidity. Integrated multi-stage nitrogen injection nozzles blanket the liquid column prior to sealing. This reduces head-space residual oxygen content below 1.0%, extending product shelf life up to 18–24 months without synthetic preservatives.

Key Sourcing Trends in Sachet Packaging Technology
1. Transition to Mono-Material Recyclable Laminates
Global environmental legislation is forcing a shift away from non-recyclable PET/AL/PE foil structures toward recyclable PE/PE or PP/PP mono-material films. Modern Chinese filling machines are equipped with precise PID digital temperature control loops and ceramic-coated sealing jaws to prevent burn-through on heat-sensitive mono-films while guaranteeing hermetic seal integrity.
2. Industry 4.0 IoT & Automatic Density Compensation
Ambient temperature variations in bottling facilities cause oil viscosity and specific gravity to fluctuate throughout the day. Advanced packaging lines now integrate inline mass flow meters linked to the Siemens PLC. The machine automatically recalculates piston dosing stroke length in real time, maintaining nominal weight tolerance without stopping production.
3. CIP (Clean-In-Place) & Rapid Product Changeover
To eliminate cross-contamination between organic extra virgin olive oil and standard canola oil, modern equipment features automatic CIP wash-down manifolds. Quick-release sanitary tri-clamp fittings allow complete dismounting of fluid piping without tools in less than 15 minutes, drastically reducing batch changeover downtime.
4. Integrated Vision Leak & Code Inspection
High-speed camera sensors inspect 100% of finished sachets for seal integrity, print clarity (batch codes/expirations), and pouch geometry. Defective sachets contaminated with surface oil drops are instantly segregated by pneumatic rejection arms, ensuring zero-defect delivery to secondary cartoners.
Our Manufacturing Capabilities & Quality Commitment
Combining European mechanical engineering standards with China's cost-effective industrial manufacturing ecosystem.
World-Class Components
We standardize standard builds with top-tier global components: Siemens S7-1500 PLC, Festo pneumatic cylinders, SICK photoelectric eye sensors, Schneider electronics, and Omron PID temperature controllers for maximum international uptime.
Full Stainless Construction
All liquid contact zones are fabricated from food-grade AISI 316L stainless steel, polished to Ra < 0.4μm, while structural frames utilize heavy-duty 304 stainless steel to resist corrosive washdown chemicals and prevent rust.
Rigorous Factory Testing
Every machine undergoes a 72-hour continuous endurance trial using customer-supplied liquid oil and packaging film prior to shipment. FAT (Factory Acceptance Testing) video verification is provided alongside full IQ/OQ validation documentation.
