Types of Liquid Packaging Machines

 Vertical Liquid Packaging Machine (VFFS)，A vertical liquid packaging machine forms the bag from film roll, fills liquid, and seals it automatically.Best for:Back-seal sachets，Three-side seal sachets，Stick packs，Small retail sachets

Production Speed Selection

When choosing an automatic liquid packaging machine, production capacity matters.

Typical speed ranges:

20–40 bags per minute (small business)

40–80 bags per minute (medium factory)

80–120+ bags per minute (industrial production)

Do not blindly choose high speed.

Higher speed means:

Higher cost

More maintenance

Higher power consumption

Choose according to actual demand.

Sealing Quality Matters

A good liquid packaging machine must have:

Airtight sealing structure

Leak-proof horizontal sealing jaws

Anti-drip nozzle

Clean cutting system

For oil, water, or detergent packaging, sealing performance is critical to avoid customer complaints.

Film Compatibility

Make sure your liquid pouch packing machine supports:

PET/PE laminated film

Nylon composite film

Aluminum foil film

Pure PE film

Film thickness and material compatibility affect sealing quality and stability.

Automation Level

Modern automatic liquid packaging machines may include:

PLC control system

Touch screen interface

Servo motor control

Auto film tracking

Fault alarm system

Optional CIP cleaning system

For export markets, CE certification is often required.

High-speed servo system: $25,000 – $60,000+

Common Mistakes to Avoid

 Choosing based only on price

 Ignoring liquid viscosity

 Buying oversized machine

 Ignoring sealing performance

 No after-sales support

FAQ
