If you pack spices, tea, namkeen or snacks in pouches, sealing is usually the slowest step. A continuous band sealer is the machine most small units move to after a hand impulse sealer.
The basic idea
A hand sealer is press, wait, lift, repeat. A continuous band sealer works more like a mini conveyor:
- Two metal bands grip the open mouth of the pouch.
- The bands carry the pouch past a heating block that melts the film layers together.
- A cooling block sets the seal.
- Rollers press the seal flat and the pouch drops out at the far end.
The operator only feeds pouches in. There is no waiting for each bag.
What you control
- Temperature: thin poly needs less heat, thick laminates need more. A wide range such as 0 to 300 deg C covers most films.
- Belt speed: faster for thin films, slower for thick ones so the heat can get through.
- Seal width: around 8 to 10 mm gives a strong, tidy seal for most retail packs.
Signs you have outgrown a hand sealer
- One person spends most of the shift only sealing
- Seals look uneven from operator to operator
- Orders are waiting on packing, not on production
