Induction sealing
A non-contact coil heats a foil liner inside the cap, bonding it to the container lip after capping.
Sealing Machines for Industrial Packaging Applications
Induction, heat, band, foil and tube sealing for secure, tamper-evident packs.
Sealing machines close a pack with a bonded seal, either under a cap (induction foil), across a film or pouch (heat or band sealing), or on the tail of a tube. A good seal depends on matching the sealing method to the liner or film material.
Types and configurations
Common approaches in this category. The right one depends on your product, pack and output.
Heat sealing
Heated jaws or plates seal films, cups and trays.
Band sealing
Continuous bands seal pre-made pouches and bags at steady speed.
Foil sealing
Cup and container sealing with die-cut lidding foil.
Tube sealing
Hot air or ultrasonic sealing for plastic and laminate tubes, crimping for aluminium.
How to choose
| Selection factor | Why it matters |
|---|---|
| Material compatibility | The liner, film or tube material must match the sealing method and the product. |
| Seal integrity | Agree how seals are tested, such as peel, leak or burst tests, before you buy. |
| Heat exposure | Heat-sensitive products and thin containers may need controlled dwell time and cooling. |
| Line speed | Sealing time per pack limits output. Check it at your real pack size. |
Where it fits in a packaging line
A typical sequence. Your actual line depends on product and pack.
- Filling
- Capping
- Induction sealing
- Labeling
- Coding
- Inspection
Technical specifications such as output, accuracy and dimensions are configuration dependent. They are confirmed against the supplier datasheet for each enquiry.

Frequently asked questions
What does induction sealing need from the cap?
The cap must contain an induction liner suited to the container material, such as PET, HDPE or glass. The liner supplier and container material decide the power and time settings.
Is induction sealing the same as heat sealing?
No. Induction sealing heats a foil inside a closed cap without contact. Heat sealing presses heated jaws directly onto film or lidding material.
How is seal quality checked?
Common checks include peel tests, vacuum leak tests and visual inspection. Some lines add sensors that reject packs with missing foil.
