Application path
Moving from a foam disc to an induction seal
A line that currently drops a foam disc into the cap can move to an induction seal — but the cap, the bottle and the line decide the format.
The buying task
The buyer wants tamper evidence and a barrier, and is considering an induction sealer in place of a foam disc. The question is whether the bottle, the cap and the line can take the change.
Conditions that change the answer
The bottle material (not metal), the cap, the line speed, the head space, the liner format and the volume. Foam + foil, foil-paper or a high-barrier structure are candidates; the sealer is only added if the line needs it.
Validation path
- 01
Check the bottle and the line
Buyer: Material, cap, speed, head space and available space for the sealer.
- 02
Choose disc or roll stock
Both: The line decides the format; the cap decides the diameter.
- 03
Trial the seal at line speed
Both: Power, speed, head gap and seal result.
- 04
Confirm the specification
Both: The liner, the machine and the settings as one combination.
Boundaries
An induction seal is not compatible with metal caps or metal bottles. The machine settings are confirmed on the buyer’s line; a lab seal is not a production result.
Candidate records
What is considered — and why.
A candidate is not a compatibility claim. The notes below say why it is on the list; the test decides whether it stays.
Foam + Foil Liners
Induction-sealed tamper evidence over a resilient foam cushion — for products that need a barrier and a compressible backing.
See the record Closure linersFoil-Paper Liners
A board-backed foil liner for jars, wide-mouth caps and dry fills, where the cap needs a flat, printable seal.
See the record Closure linersHigh-Barrier Liners
A foil-based structure for solvents, essential oils and formulations that would migrate through a simple foam or paper liner.
See the record EquipmentLGYS-4000 Induction Sealing Machine
A water-cooled induction sealer for round plastic and glass bottle necks, supplied as a key-panel or touch-screen model and set up around the liner.
