Induction Sealing vs Heat Sealing: Choosing a Sealing Machine
Quick answer: Use an induction sealer for bottles and jars: it melts a foil liner inside the cap onto the bottle neck to give a leak-proof, tamper-evident seal. Use a heat sealer (hand, foot or band sealer) for plastic bags, sachets and pouches. Many plants use both.
Key facts
- Bottles and jars → induction sealer + foil liners
- Bags, sachets and pouches → heat sealer
- Band sealers seal and code in one pass
- Tamper-evident seals build customer trust

- Keep heat-sealer bars clean and the temperature steady.
Frequently asked questions
What is induction sealing?
A foil liner inside the cap is heated by an electromagnetic field and bonds to the bottle neck, making a leak-proof, tamper-evident seal.
Which sealer is best for plastic bags?
A hand or foot operated heat sealer for low volume, or a band sealer for continuous work.
Do I need special caps for induction sealing?
Yes, caps fitted with induction liners that match the bottle.
Can a sealer also print the date?
Yes, some band sealers have a coding unit that prints as they seal.
