Don’t Let Packaging Be
Don’t Let Packaging Be
Your Bottleneck.
Manual packing leads to inconsistent weights, high labor costs, and slow throughput. Our fully automated systems integrate weighing, bag forming, filling, and sealing into one seamless high-speed operation.
Precision Weighing
Stop giving away free product. Our Multi-Head Weighers calculate the perfect combination to reach target weight with ±0.5g accuracy, saving tons of raw material annually.
High-Speed Servo
Dual servo motors control film pulling and sealing independently. This ensures precise bag length and print registration at speeds up to 100 bags/minute.
Extended Shelf Life
Integrated Nitrogen Gas Flushing removes oxygen from the bag before sealing. This prevents oxidation, keeping chips crispy and nuts fresh for months.
Choose Your Packaging Architecture
The physical state of your product determines the machine type. Use Vertical for gravity-fed loose items and Horizontal for solid unit items.

The Complete Packaging Loop
We integrate separate components into one synchronized system. From the Z-Elevator to the Output Conveyor, every step is automated and controlled by a central PLC.
01
Feeding & Elevation
Z-Bucket Elevator lifts the product from ground level to the top of the weigher automatically.
02
Multi-Head Weighing
Computer calculates the precise combination of buckets to reach the target weight instantly.
03
Form, Fill & Seal
The VFFS machine pulls the film, forms the bag, fills it with product, and heat-seals it shut.
04
Conveying
Finished bags drop onto the Output Conveyor and are transported to the check-weigher or rotary table.
System Layout
The Brain & The Muscle
High-performance packaging requires synchronization between three critical systems: Weighing, Film Transport, and Sealing.
The Brain
Multi-Head Weighing System
The microcomputer instantly calculates the optimal combination from 10 or 14 weighing hoppers to match your target weight. It eliminates the “overfill” problem of traditional cups, saving tons of material annually.
Accuracy: ±0.1-1.5g
Speed: Up to 130 dumps/min
Dimple Plate (Anti-stick)
IP65 Waterproof
The Muscle
Double Servo Film Transport
Unlike old pneumatic systems, our VFFS machine uses Double Servo Motors to pull the packaging film. This provides constant tension, smoother motion, and precise bag length control without slippage.
Precise Registration
No Film Wandering
Quiet Operation
Auto-Correction System
The Seal
PID Temperature Control
A beautiful bag is useless if it leaks. Our independent PID temperature controllers ensure the sealing jaws maintain a constant heat within ±1°C, guaranteeing an airtight seal even at high speeds.
Independent Control
Safety Obstruction Sensor
Clean Cutting
Multi-Film Compatible

Smart Investment
Turn Accuracy Into Net Profit.
The hidden cost of packaging isn’t the machine price—it’s the “Product Giveaway”. Every gram you overfill to be safe is profit leaving your factory.
Loyal’s microcomputer combination weighers reduce deviation significantly compared to manual or cup-filler systems. You save raw material on every single bag, paying back the equipment cost in months.
-
Reduce Giveaway: From ±3g down to ±0.2g.
-
Save Labor: One machine replaces 4 manual workers.
-
Zero Underweight: Auto-reject function ensures 100% compliance.

Common Questions
Answers about bag sizes, materials, and machine operation.
How do I change the bag width?
To change the bag width, you simply replace the Bag Former (the metal forming tube). We design our formers for “Tool-Free” changeover, which takes an experienced operator about 5-10 minutes.
What kind of packaging film should I use?
Our machines work with most heat-sealable laminated films, such as BOPP/CPP, PET/PE, or Aluminum Foil. If you are using single-layer PE (Polyethylene), please inform us, as it requires a specialized sealing system.
Can one machine pack different weights?
Yes. The same machine can pack a wide range of weights (e.g., from 15g to 1kg) by simply adjusting the settings on the touch screen. However, if the volume difference is huge, you might need to change the bag size.
What are the wear parts?
The most common consumables are the Teflon belts (for pulling film), cutting knives, and heating elements (cartridge heaters). We include a spare parts kit with every machine delivery.
Can you add Nitrogen Flushing for chips?
Yes. We can integrate a Gas Flush Module directly into the VFFS former. This pumps nitrogen into the bag just before sealing to displace oxygen, keeping fried snacks crispy and extending shelf life.
