Bag Sealing Machines: Choosing a Hand, Foot or Continuous Band Sealer
- Heat + pressure fuse the bag layers
- Hand: small volumes; foot: faster; band: production
- Set heat time for the bag thickness
- Band sealers can print batch codes

Types of Bag Sealers
| Type | How it works | Best for |
|---|---|---|
| Hand impulse sealer | Press the arm; a short heat pulse seals the bag | Shops and small producers |
| Foot-operated sealer | Pedal closes the jaws; both hands hold the bag | Busy packing tables, thicker bags |
| Continuous band sealer | Bags travel through heated bands on a conveyor | Production lines; can code as it seals |

Getting a Good Seal
- Set the heat time for the bag: too low gives a weak seal; too high burns through.
- Let the seal cool under pressure before releasing.
- Keep the sealing area clean of powder, oil and liquid.
- Replace worn Teflon tape and heating elements.
- Test seals by squeezing or pulling sample bags.
Which Bags Can Be Sealed?
Most polythene (PE) and polypropylene (PP) bags and many laminated or foil (mylar) pouches can be heat-sealed; check that the bag's inside layer is heat-sealable.
Cups, Bottles and Codes
For cups use a cup sealer (cup sealing); for bottle caps, induction sealing (induction vs heat sealing). Dates and batch numbers: batch coding.
Frequently asked questions
Which sealing machine is best for small businesses?
A hand impulse sealer for small volumes; a foot sealer when you pack many bags a day.
What is a continuous band sealer?
A machine that seals bags as they travel through heated bands on a conveyor, often printing a code too.
Why are my bag seals weak?
Heat time too short, dirty sealing area, worn Teflon tape, or releasing before the seal cools.
Can foil bags be heat sealed?
Many laminated foil (mylar) pouches can, if the inner layer is heat-sealable.
