Sigma Jet: Our Fastest 100 FPM Induction Cap Sealer
A 100 feet-per-minute automatic inline sealer manufactured for high-volume production lines. Waterless, air-cooled, and ready to run out of the box.
The Sigma Jet tops the range for output: 20 to 100 mm caps, a waterless air-cooled coil, fully assembled on delivery. Sigma CapSeal manufactured India’s first indigenous induction sealer in 1989 and the Jet won the Best Pac Machine Award in 2015.

Self-Standing Design
The Flagship Sealer for High-Speed Lines
The Sigma Jet sits at the top of the Sigma range. It runs at 100 feet per minute, the fastest we manufacture, and it ships fully assembled so it fits most lines without modification. The frame is self-standing and the machine is with castor wheels.
Recipes sit behind a password, rejects are counted automatically, and every run logs to a basic audit trail. If your line needs full FDA 21 CFR Part 11 records and electronic signatures on top of that, pair it with the CFR compliance package.
How the Sigma Jet Works
An induction sealer bonds a foil liner to the container mouth via an electromagnetic field. The Sigma Jet does that at up to 100 feet per minute, so you get the desired output.
1
Feed and Convey
Containers move down the line already capped, passing under the sealing head at up to 100 feet per minute. It is a fully automated system.
2
Induction Seal
The coil generates an electromagnetic field to the foil liner as each bottle passes under it. The sealing head delivers a full wax melt, so you get hermetically sealed bottles.
3
Inspect and Reject
Any missed seal is detected and rejected, and shown on the touchscreen.
4
Recipe Management
Customer can store recipe of the production.
Key Features and Engineering Advantages
What you get on Sigma CapSeal’s fastest sealing equipment.
100 FPM, Top of the Range
Nothing else in the Sigma lineup runs faster. It’s sized for lines that don’t stop, shift after shift.
Bottle Jamming Detectors
Detect backup of bottles at in-feed and out-feed, so a pile-up stops the line instead of running through the sealing head.
Bottle Counter
One universal head seals the full range with no head swaps. It standardizes sealing across many SKUs.
Batch Processor
You can specify how many bottles you would like to seal in the batch.
No Foil Detector
Detects the presence or absence of an induction foil liner/wad in the cap/bottle.
No Cap Detector
Detects the absence of a cap automatically.
Waterless and Air-Cooled
Detects the absence of a cap automatically.
Cap and Container Compatibility
We can provide a sealing head as per your diameter design. The universal design covers 20 to 120 mm without a coil swap between SKUs.

Output and Cost of Ownership
100 FPM
Speed to Output
100 feet per minute is the conveyor speed, not the container count. Give us your bottle & cap diameter and we will give you a number.
Fewer Rejects
Fewer Rejects, Lower Waste
On-board inspection detects a missed seal before it enters the induction sealing equipment, which brings the cost per sealed bottle down.
No Chiller
Lower Running Cost
The 100% air-cooled coil needs no water. One less system to plumb, power and maintain.
Inspection, Rejection and Recipe Management
The touch screen watches the seal, drops the failures, and keeps a basic log of what happened.
- In-line inspection and rejection on every seal
- Password protection with operator lockout
- Recipe management for repeatable changeover
- Descriptive faults and basic operating data logs
What You Get Standard
Password-protected recipes, reject counts, and basic operating logs, straight from the machine. No manual tracking of settings between shifts.

Dairy
Airtight seals on dairy cups and bottles through cold-chain handling.
Lubricants & Break Fluid Oils
Spill-proof seals on thick, slippery lube and motor-oil fills.
Agro Chemicals / Insecticide / Pesticide
Secure seals across mixed cap sizes. Used by Syngenta.
Petro Chemicals
Reliable foil seals at high-volume packing rates.
Personal Care

Specialty Chemicals & Adhesives
Solvent-tight foil seals on adhesives, resins, coatings and specialty chemical packs, so aggressive contents stay contained and evaporation-free through storage and transit.
Power and Line Integration
Plan for three-phase power; that’s the one difference from the single-phase models lower in the Sigma range. Everything else about getting it running is straightforward.
- Operates on 415 ± 10% V AC, three phase, 50/60 Hz — confirm a three-phase supply is available at the install point
- Fully assembled — ready to slot into most existing lines
- Standalone equipment
- Rolls on castor wheels and locks down on station pads at changeover
- Coil head moves 350 mm vertically, with an indicator and a lock so the height stays put

Frequently Asked Questions: Sigma Jet
What packaging engineers and procurement teams ask before they buy.
Is the Sigma Jet 21 CFR Part 11 compliant?
The standard Sigma Jet ships with password-protected recipe management and a basic audit trail. For full USFDA 21 CFR Part 11 compliance, including electronic records, electronic signatures and a complete audit trail, choose Sigma Jet + CFR.
How fast is 100 FPM in containers per minute?
It’s a conveyor speed, not a container count. The actual number depends on your bottle spacing and cap diameter. Give us your bottle & cap diameter and we will give you a number.
Is it water-cooled or air-cooled?
100% air-cooled. There is no water circulation required, which is one less thing that can take the line down.
How is it different from the Sigma III Touch?
The Sigma III Touch is single phase while the Sigma Jet is three phased. The III Touch runs at 80 feet per minute. The Jet runs at 100 and tops the range for output.
Does it need three-phase power?
Yes. The Jet operates on 415 ± 10% V AC, three phase, 50/60 Hz, so plan a three-phase supply at the install point. See Power and Installation.
Can I upgrade a standard Sigma Jet to CFR compliance later?
Talk to our applications team about your specific unit. Ask us whether your line is best served by ordering CFR-ready from the start or reviewing an upgrade path.
