An 80 FPM Sealer That Runs Itself
The Sigma III Touch is the automatic, inline workhorse of the Sigma sealing range. It is the step up from semi-automatic and entry inline models for high-volume lines that cannot stop. The self-standing design needs no mounting brackets and no cart, so it drops into your line and locks in place.
One universal sealing coil seals every cap from 20 mm to 120 mm, and touch-screen recipe management makes SKU changeover near instant. Castor wheels and station pads let you relocate and secure the machine in minutes, so a line changeover never becomes a project.
How the Sigma III Touch Works
1
Feed and Convey
Capped containers move on the conveyor at up to 80 feet per minute under the sealing head (Sealing coil). No manual handling and no operator at the head.
2
Induction Seal
3
Inspect and Reject
4
Monitor and Repeat
A clean seal depends on line speed, power output and cap torque. The recipe holds these settings for you, so a run stays consistent and auditable for quality records from the first bottle to the last.

Key Features and Engineering Advantages
80 FPM Inline Throughput
Automatic conveyor sealing at up to 80 feet per minute for high-volume, continuous lines that run all shift.
Touch-Screen and Recipe Management
An intuitive HMI with supervisory password and operator lockout, stored recipes, and descriptive fault information.
Inspection, Rejection and Counters
On-board seal inspection with reject control, plus container, cap and foil counters that keep every run auditable.
IGBT, 100% Digital Variable Output
Solid-state power with no tap changing on the transformer and no effect from voltage fluctuation, so the seal stays stable.
Waterless, 100% Air-Cooled, Ambient Operation
No water circulation and no water lines. This removes a common downtime source and cuts the maintenance and floor-space cost.
Universal Coil and Fast Changeover
One coil seals 20 to 120 mm. With 350 mm head travel, a height indicator, a position lock, castor wheels and station pads, changeover is quick and repeatable.

Throughput and Total Cost of Ownership
80 FPM
Line Speed to Containers Per Minute
Eighty feet per minute is the conveyor speed. With small pharma and nutraceutical caps, that handles a few hundred containers per minute, depending on your container diameter and pitch. Share your sizes and we confirm the exact rate.
No Water Requirement
Waterless Running Cost
The 100% air-cooled coil runs at ambient temperature with no water circulation to power or maintain. You remove a whole class of running cost and a common downtime source.
IGBT
Power-Efficient and Stable
Solid-state IGBT power with 100 percent digital variable output keeps the seal stable through voltage swings and avoids tap changing, which protects uptime and lowers energy waste.
Fewer maintenance tasks, faster recipe-based changeover and a stable seal lower your cost per sealed container. Total cost of ownership beats a low sticker price.
Inspection, Rejection and Production Data
The touch screen is more than a control panel. It watches every seal, removes the ones that fail, and keeps a record your quality team can audit. This is the capability that separates the III Touch from entry and semi-automatic sealers.
- Touch-screen control for inspection and rejection of every seal
- Supervisory password protection with operator lockout
- Recipe management for instant, repeatable SKU changeover
- Container, cap and foil counters for full run accountability
- Descriptive fault information and internal monitoring of all critical operating data
Audit-Ready by Design
Data logging and reject control support GMP and quality requirements out of the box. For lines that need full CFR 21 Part 11 compliance, the Sigma Jet CFR21 model adds compliant, auditable sealing on the same platform.

Where the Sigma III Touch Is Used
Pharma & Healthcare
Tamper evidence and a moisture barrier for high-speed tablet and syrup lines. Trusted by names like Sun Pharma and Dr. Reddy’s.
Nutraceutical
High-throughput foil seals on supplement and powder bottles across mixed SKUs.
Food & Beverages
Freshness and leak prevention at line speed for sauces, syrups and powders. Trusted by names like Nestle, Tata Tea and ITC.
Dairy
Clean, airtight seals on dairy cups and bottles that block spills in transit.
Personal Care & Cosmetics
Leak protection and theft evidence for lotions, creams and oils. Trusted by packers like Alpla and Weener.
Agro Chemicals
Secure seals across mixed cap sizes on agrochemical bottles. Trusted by names like Syngenta.
Petro Chemicals
Foil seals for petrochemical containers in high-volume packing.
Speciality Chemicals
A reliable barrier under the cap for aggressive specialty chemical contents.
Compliance and Safety, Built In
The Sigma III Touch is a GMP model, designed in a DSIR-certified R and D environment with password-protected recipes, data logging and reject control that support audit requirements. For lines that need full CFR 21 Part 11 compliance, the Sigma Jet CFR21 model runs on the same platform.
Seals rarely fail without a reason. The usual variables are air gap and coil height, line speed, power output, cap torque and a contaminated neck finish. The recipe holds your proven settings, and the on-board monitoring flags drift before it becomes a reject.

Frequently Asked Questions: Sigma III Touch
Common questions from packaging engineers, production managers, QA teams and procurement evaluating the Sigma III Touch.
How fast is the Sigma III Touch in containers per minute at 80 FPM?
80 feet per minute is the conveyor speed. Containers per minute depend on your container diameter and spacing, but for small pharma and nutraceutical caps it is usually a few hundred per minute. Send your sizes and we confirm the exact rate.
Is the Sigma III Touch a GMP and USFDA 21 CFR compliant machine?
Yes. It is a GMP model built in a DSIR-certified R and D environment, with password-protected recipes, data logging and reject control for audits. For full CFR 21 Part 11, choose the Sigma Jet CFR21 on the same platform.
What cap sizes and closure types can the universal coil seal?
One universal coil seals every cap from 20 mm to 120 mm with no coil swaps. Flat, deep tunnel, peep tunnel and custom heads cover CRC, dome, sports and spout, snap-on, flip-top, continuous-thread and conical closures.
How does it differ from the Sigma II Neo Touch and the Sigma Jet?
All are inline sealers on one platform: the II Neo Touch runs at 55 feet per minute, the III Touch at 80 with full recipe and reject control, and the Jet at 100 for maximum throughput.
Does it need a water chiller?
No. It is 100 percent air-cooled and runs at ambient temperature, with no water circulation required.
How does the inspection and rejection system work?
The touch screen checks each seal and flags any that miss. Reject logic removes them, and container, cap and foil counters keep the run auditable.
