Water-Cooled Electromagnetic Sealer
Induction Foil Sealing Machine
Seal the bottle, not the cap. A high-frequency coil heats the aluminium foil liner inside the closure until it fuses to the neck, so every container leaves the line tamper-evident and airtight without a single contact with the product.

Containment Without Contact
Why Induction Beats Contact Sealing on a Bottle Line
A contact head has to reach the neck, apply pressure and release. An induction head never touches the product at all: it passes over the capped bottle and heats only the foil liner, which means no residue, no smearing and no mechanical wear on the closure.
- Seal through the capThe liner fuses to the neck from the outside in, so the closure stays clean and intact.
- Water-cooled headContinuous output without heat soak, which keeps the seal flat and the cycle repeatable.
- Dielectric materials onlyPE, PP, PET, PS, ABS and glass are ideal; metal bodies and metal caps are excluded by the process.
- Line-readyRuns inline with filling and capping equipment or as a standalone bench unit.
Sealing Principle
How the Foil Seal Forms in Four Stages
No adhesive, no flame and no hot tool touching the product. The seal is created by the liner itself.
01
Field Couples
The sealer coil generates a high-frequency field as the capped bottle passes beneath it.
02
Liner Heats
The aluminium foil layer absorbs the field and rises in temperature within a fraction of a second.
03
Polymer Fuses
The heat-seal coating on the foil melts and bonds to the bottle neck, forming a continuous membrane.
04
Seal Sets
On leaving the field the bond cools and locks, leaving a tamper-evident, moisture-proof closure.
Technical Data

Digital Monitoring
Working voltage and current are shown continuously, so a drift in the seal is caught at the panel, not downstream.
Automatic Protection
Over-current and over-voltage faults trip the unit automatically, protecting both the coil and the production batch.
Integrated Build
Power supply, coil and cooling sit in one stainless cabinet, leaving a single unit to position over the conveyor.
Container Fit
Bottle Neck and Container Coverage
Two standard coil sizes cover the range from small dropper bottles to wide-mouth jars. The table shows which coil suits which neck.
| Neck diameter | Typical container | Coil size |
|---|---|---|
| 15-30 mm | Pharmaceutical dropper and syrup bottles | 15-60 mm |
| 30-45 mm | Cosmetic and essential oil bottles | 15-60 mm |
| 45-60 mm | Beverage and nutraceutical bottles | 15-60 mm |
| 50-90 mm | Wide-mouth supplement jars | 50-130 mm |
| 90-130 mm | Chemical and oil containers | 50-130 mm |
Metal bottles and metal caps are not compatible with induction sealing. For lined plastic or glass closures the process works across the full range above.
Where It Earns Its Place
Industries That Seal Foil Every Shift
Any line that fills a bottle and needs a moisture barrier, a tamper seal or an oxygen barrier is a candidate.
Pharmaceuticals
Airtight, tamper-evident seals on syrup, tablet and dropper bottles where cleanliness and traceability are mandatory.
Food & Beverage
Freshness locks on sauces, condiments, juices and dairy, keeping the headspace product from oxidising after capping.
Cosmetics & Oils
Leak-proof closures on lotions, serums, essential oils and lubricants, sized for both narrow and wide mouths.
A
Supplements & Nutraceuticals
Seals keep moisture out of hygroscopic powders and protect sensitive actives in high-humidity warehouses.
B
Chemicals & Agro
Barriers against leaks and fumes on pesticide, fertiliser and industrial chemical containers.
C
Contract Packing
A single sealer that changes coil to switch between bottle families, keeping short runs economical.

FAQ
Induction Foil Sealing Questions
PE, PP, PET, PS, ABS and glass containers are all supported. Metal bottles and metal caps cannot be used, because the induction field has to pass through the cap into the foil liner.
The sealing speed is rated from 0 to 250 bottles per minute. The achievable figure depends on bottle diameter, line pitch and the liner used, so we confirm it against your container.
The unit is water-cooled as standard, which keeps the sealing head stable during long shifts. The cooling circuit is specified with the machine so it matches your utilities.
Yes. The sealer can be integrated into an automatic line or operated as a standalone unit, which makes it suitable for both new projects and upgrades of existing filling and capping equipment.
The display shows working voltage and current so the operator can see the sealing condition at a glance. Over-current and over-voltage protection trips automatically to keep the machine safe.
Standard production takes about 5 working days. Air express adds roughly 4-6 working days, and air or sea freight is arranged for larger quantities. Every shipment is trackable.
The machine carries a 2-year free warranty covering parts, plus English online support by email, WhatsApp and remote assistance for the life of the equipment.
