Inline induction sealers for continuous foil sealing lines
Inline induction sealers are installed after cap application so foil-lined closures can be sealed without direct contact. This page helps buyers compare line position, conveyor speed, cap range and sealing-head setup before requesting a quote.
When an inline induction sealer is the right choice
Choose inline induction sealing when the pack is already capped and needs a consistent tamper-evident foil seal before labelling, coding or final packing. The machine should be specified around the slowest or most variable part of the packaging line, not just a catalogue speed. Bottle spacing, cap diameter, liner construction and container material all affect how long the foil must remain under the induction field.
Line data to confirm before quotation
Useful quote data includes cap diameter range, container height range, conveyor width, conveyor height, target bottles per minute, foil liner type and available power. This information allows Lancing UK to check whether a standard inline arrangement is suitable or whether the line needs additional handling, spacing or guide-rail work.
Common risks to avoid
Weak seals are often caused by the wrong liner, poor cap torque, too much speed for the available dwell time, incorrect head height or inconsistent container presentation. A good specification process checks these details before the machine is installed.
For a faster recommendation, send cap diameter, liner type, container material, bottle height, conveyor details and target output to Lancing UK.

Inline sealing is a relationship between power and the time each foil liner spends in the effective induction field. Conveyor speed, spacing, cap diameter and head alignment therefore need to remain within the proven operating range.
| Speed changes | Link speed changes to the approved setup or recipe; do not alter conveyor rate without reviewing dwell and seal checks. |
|---|---|
| Line stops | Define how the sealer and conveyor respond so a pack is not left under uncontrolled exposure. |
| Accumulation | Prevent back-pressure, bottle contact or erratic gaps from changing cap alignment beneath the head. |
| Changeovers | Record guide rails, head height, cap/liner group, power and speed before releasing the new format. |
| Interfaces | Use complete packaging-line guidance where the wider fill-cap-label system must be coordinated. |
