Bottle Continuous Induction Sealer for Aluminum Foil
The SUNAURA bottle continuous induction sealer for aluminum foil is the most price-accessible continuous (not handheld) sealer in our range. A compact floor-standing unit with an integrated belt conveyor (~0–12 m/min, Φ20–80mm), it gives small operations genuine aluminum-foil tamper evidence at the lowest entry price.
Product Description
The SUNAURA bottle continuous induction sealer for aluminum foil is our entry point to continuous conveyor sealing. Unlike a handheld wand, this is a genuine floor-standing continuous unit with its own belt conveyor — small bottles feed through hands-off while the head seals each cap automatically. That removes the slow, labor-intensive hand-sealing step without the cost of a full production model.
It is aimed squarely at cost-sensitive buyers: small workshops, start-ups, and secondary packers who need real aluminum-foil tamper evidence but run low-to-medium daily volume on small-to-medium bottle sizes. The trade-off versus our mid-range machines is honest and intentional — a narrower sealing window (~Φ20–80mm), lower power (~1500–2000W), and a lighter frame (30–50kg). For the volumes this machine is designed for, that is fully adequate, and the simple knob/button operation means an operator can run it with almost no training.
Air cooling means no water supply or chiller, and the compact frame sits on adjustable feet. It is also well suited to OEM and private-label channels. Every unit is CE certified and backed by a 12-month warranty with lifetime support from our Qingdao factory.

- Compact Floor-Standing Frame: Small footprint on adjustable feet fits benchtop-adjacent work cells and tight workshop floors without permanent installation.
- Air-Cooled, No Water Required: Forced-air cooling needs no supply, drain, or chiller — just plug into a 220V outlet and seal.
- Simple Knob / Button Operation: Straightforward controls for speed and power mean minimal operator training and fast changeovers.
- Integrated Conveyor for Hands-Off Feeding: Small bottles ride the belt through the head automatically, freeing the operator to load and pack.
- Configurable Power & Head: Choose the 1500–2000W generator and head size that match your bottle range, so you pay only for what you need.
- OEM / Private-Label Friendly: Clean, utilitarian build suited to white-label resale and contract-packer channels.
- Factory-Direct & CE Certified: Built in our Qingdao plant, covered by a 12-month warranty and lifetime technical support.
Application Industries
This budget continuous sealer fits low-to-medium volume bottling where tamper evidence is required but a full production line is overkill.
Small Workshops & Start-Ups
Founders and small teams needing their first proper foil-sealing station at a realistic price point.
Food & Condiments
Sauces, dressings, and small-batch foods in PET, HDPE, or glass — prevents leakage and adds consumer trust.
Cosmetics & Small Batches
Serums, toners, and small personal-care bottles — hermetic foil seals protect products during shipping.
Chemicals & Small Liquids
Sample and small-format chemical liquids — leak-proof sealing avoids spills and contamination.
Secondary / Contract Packing
Packers adding tamper-evident seals to existing bottled goods as a secondary operation.
Container Types
Seals non-metal small-to-medium bottles in PET, HDPE, and glass, up to ~300 mm tall.
How Induction Sealing Works
Induction sealing bonds an aluminum foil liner to the bottle mouth using electromagnetic energy — no contact with the cap. The cycle on this compact continuous unit:
- Capped small bottles feed under the head. Pre-capped bottles ride the compact belt conveyor beneath the RF sealing head at the selected speed.
- Field induces current in the foil. The generator drives a high-frequency magnetic field that induces eddy currents in the aluminum foil, heating it almost instantly.
- Wax melts, film bonds to the rim. Heat melts the wax into the pulp board while the heat-seal film fuses to the container mouth.
- Cap removed, foil seal remains. Unscrewing the cap leaves the pulp inside the cap and the aluminum disc bonded to the mouth — visible tamper evidence.
- Air cooling keeps the unit simple. Fan cooling maintains stable output without any water circuit, keeping setup and maintenance minimal.
How to Choose the Right Entry-Level Continuous Sealer
This machine is the smart entry point when volume and bottle sizes stay modest. Confirm fit with these four checks:
- Confirm your bottles fit Φ20–80mm. The budget head covers small-to-medium caps. If you need wide-mouth jars or caps above ~80mm, move up to a wide-head or large-head model.
- Estimate your daily volume. At ~0–12 m/min this suits low-to-medium daily output. If you run high volumes for hours every day, a higher-power continuous sealer will be more productive per dollar.
- Plan for the simple duty cycle. Air cooling suits intermittent, start-up-scale running. It needs no water and minimal maintenance — just a 220V outlet and level floor.
- Leave headroom for growth. We can configure power and head size to your current SKUs. Tell us your planned growth so we spec a unit you will not outgrow in six months.
Troubleshooting Guide — Common Issues & Solutions
Entry-level continuous sealers are simple, but set-up issues still appear. Below are the most frequent problems on this model, their causes, and fixes. Always disconnect power before inspecting the sealing head.
| Problem | Possible Causes | Solutions |
|---|---|---|
| Weak or partial foil seal | Conveyor too fast; head too high; low power; wrong liner type. |
|
| No heat / foil not bonding | No RF output; loose head connector; non-induction liner; off-center bottle. |
|
| Seals off-center on small caps | Bottle guide crooked; belt tracking off; cap not centered on neck. |
|
| Overheat trip after a run | Continuous running beyond duty cycle; blocked fan; hot room. |
|
| Bottles jam on the belt | Guide gap too tight; tall bottles tipping; sensor blocked. |
|
| Uneven seal strength between bottles | Fill level varies; cap torque inconsistent; liner mis-seated; dirty head. |

Frequently Asked Questions
Why is this the cheapest continuous sealer in your range?
It uses a lower-power (~1500–2000W) generator, a narrower sealing window (~Φ20–80mm), and a lighter 30–50kg frame. We deliberately trimmed cost to the essentials for low-to-medium volume. For the bottle sizes and volumes it is designed for, it still produces a full, reliable aluminum-foil seal — you are not paying for wide-head or high-speed capacity you do not need.
How is this different from a handheld induction wand?
A handheld wand seals one cap at a time by hand and suits very low volume. This unit is a genuine continuous machine with its own belt conveyor: you place capped bottles on the belt and they pass under the sealing head automatically. It removes the hand-feeding step and scales to steady low-to-medium production.
What bottle sizes and materials can it seal?
It seals non-metal small-to-medium bottles up to about 300mm tall with caps in the ~Φ20–80mm range, in PET, HDPE, and glass. Power and head size are configurable to your exact SKUs. Send us your samples and we will confirm the right configuration before you buy.
Do I need water or special utilities?
No. This is an air-cooled unit that needs only a standard 220V power outlet and a level, ventilated floor. There is no water supply, drain, or chiller, which keeps installation cost and maintenance to a minimum.
What is the warranty and lead time?
Every unit carries a 12-month warranty on parts and labor plus lifetime technical support by email, WhatsApp, and remote video. Standard models ship in 7–15 days, and spare parts are dispatched worldwide within 48 hours.
