Heat Sealing Machine

'Heat sealing machine' is the widest of the names. It covers everything that closes a pack with heat, which is several quite different machines. This page sorts them so you can find the one your pack actually needs.

Every machine on this page does the same physical thing: it melts two surfaces together so that what is inside stays inside. What separates them is the pack - a flat bag, a stand-up pouch, a cup with a film lid, a jar with a foil wad - and the volume.

Buyers arrive at this term from both directions. Some know exactly which machine they want and use the general word out of habit. Others have a pack in mind and no idea what the machine is called. Both are common, so this page is organised by the pack rather than by the machine name.

If your pack is a flat bag or a pouch

This is the largest group by a distance, and it is the impulse and band family. The bag mouth is laid flat and closed with a straight seal across it.

Within that, the format follows the volume and the operator: a hand-pressed bar for occasional work, a foot pedal when the bag needs both hands, a table top machine for steady shift work, and a continuous band sealer once bags are queuing.

If your pack is a cup or a tray

A cup sealer is a different machine. A pre-cut film lid is placed on the cup rim and a heated die presses it down, sealing right around the rim. That is what closes a curd or lassi cup, a juice or drink cup, a sweet or dessert cup and a takeaway container.

The die is made for the cup, which is why the cup - not the volume - is the first thing to settle. Send the cup and the lid film with your enquiry.

If the pack has to keep air out

Heat sealing closes a pack; it does not empty it. If the point of the pack is shelf life rather than containment, the machine you want removes or replaces the air before it seals.

Vacuum machines draw the air out. Gas flushing replaces it, which is what you need when a hard vacuum would crush the product. Both are separate ranges and both end in a heat seal, which is why buyers often arrive here first.

If the film has to shrink around the product

Shrink packaging is heat sealing followed by a second heat stage. The film is sealed round the product or the multipack first, then a tunnel shrinks it tight to the shape. Multipacks of bottles, tins, soaps and books are made this way.

If what you are picturing is a tight transparent skin rather than a bag with a seal across the top, this is the range to look at.

What we need to point you at the right one

A photograph of the finished pack you want, the material it is made of, and how many you make in a day. From those three we can name the machine, and if it is not one we supply we will say so rather than sell you something adjacent to it.

Induction sealing, and why it looks like nothing at all

There is one more member of this family worth knowing about, because buyers meet it constantly and rarely realise it is a heat seal.

The foil disc under the cap of a bottle of oil, a jar of pickle or a container of supplements is applied by induction. The cap goes on with the foil wad inside it, the bottle passes under a head, and a magnetic field heats the foil so that it bonds to the rim of the container. Nothing touches the bottle and no visible machine mark is left.

It is the answer whenever the pack is a rigid container rather than a bag, and whenever a customer needs to see that a pack has not been opened before. That combination covers most edible oil, sauce, honey, nutraceutical and cosmetic packing in India.

If what you were looking for is a tamper-evident seal on a bottle or a jar rather than a seal across a bag, this is the machine, and it belongs with the capping range rather than with the bench sealers.

Heat sealer types at a glance

A heat sealer joins two layers by warming them until they fuse, and the four types we make warm them in different ways. An impulse sealer heats a thin wire for a moment and is cold the rest of the time – see the impulse sealer range. A hot bar sealer keeps its bar hot, which suits foil and metallised film – the FS300D / 400D. A band sealer carries the pouch between heated blocks on a belt – the continuous band sealer. An induction sealer heats a foil wad inside a bottle cap without touching it – the IS100 and IS200.

Not sure which one matches your pack? The chooser on the sealing machines page answers it in one line.

Which film each heat sealer can close

Impulse: PE, LDPE, HDPE, PP and PE-lined laminates up to about 150 micron, with a 2 mm seal on the hand models and 5 mm on the FS pedal series. Hot bar: aluminium foil, metallised and laminated pouches, with a 10 mm seal across 300 or 400 mm on the FS300D / 400D. Band: pouches carried on a belt at up to 12 metres a minute on the CS900; the CS1680 takes thicker film of 0.12 to 0.18 mm and up to 15 kg on its conveyor. Induction: a foil wad under a plastic cap, from 20 to 135 mm across on the IS100.

Heat sealer price, type by type

A hand impulse sealer starts at ₹1,348 + ₹243 GST, a hot bar foot sealer at ₹30,284 + ₹5,451 GST, a continuous band sealer at ₹12,812 + ₹2,306 GST and a continuous induction sealer at ₹58,240 + ₹10,483 GST. The full table, one row per type, is on the sealing machine price list.

Heat sealers for cups and cans

Not every pack is a bag. The manual cup sealing machine closes lassi, juice and curd cups at about 300 to 400 cups an hour, and the ECS150 seams a metal lid onto cans of 39 to 150 mm at 10 to 25 a minute. Both are covered for 12 months on manufacturing defects, wear parts excluded.

Where each heat sealer is used

Namkeen, spice and grocery packers close plain PE pouches on impulse sealers, and move to a continuous band sealer when the packets come off the filling bench without a pause. Tea, coffee and spice brands that pack in foil or metallised pouches use the hot bar foot sealer, because constant heat closes those films where a short impulse cannot. Pickle, oil and pharma packers fit a foil wad under the cap and seal it with an induction sealer, which never touches the bottle. Dairies and juice counters close lassi, curd and juice cups on the cup sealer, and ghee, oil and food packers seam metal lids onto their tins with the ECS150.

Power and warranty

Heat sealers draw very different amounts of power. A hand impulse sealer uses 215 W on the 8 to 12 inch sizes and up to 700 W on the 24 inch, and only while the arm is down. The CS900 band sealer is rated at 650 W, the IS100 induction sealer at 500 W and the IS200 at 2000 W. Hand impulse sealers carry 2 or 5 years of warranty; the other types carry 12 months on manufacturing defects, with wear parts excluded.

Questions we are asked about this

Is a heat sealer the same as an impulse sealer?

An impulse sealer is one kind of heat sealer - the bench kind that heats only while the jaws are closed. Band, hot bar, cup and induction machines are also heat sealers and work differently.

Which heat sealing machine do I need for pouches?

For flat and stand-up pouches, the impulse and band family. Which one depends on your daily count and whether the pouch needs both hands. Send the pouch and the count.

Can one machine handle bags and cups?

No. A cup sealer's die is made for the cup rim and a bar sealer makes a straight seal. They are different machines and there is no sensible overlap.

Does a heat sealer preserve food?

It closes the pack. Shelf life comes from removing or replacing the air, which is vacuum and gas flushing work, or from the barrier properties of the film itself.

What seals the foil under a bottle cap?

An induction sealer. The cap is applied with a foil wad inside, and a magnetic field bonds the foil to the container rim without anything touching it.
