Ever wondered how most of our food items get sealed? but couldn’t really wrap your head around it because you were busy eating?! … Well, no worries, we’ve got you covered when curiosity hits again!

Hand Sealing systems are used to seal containers for consumer, bulk, and original equipment (OEM) shipments of liquids, granules, powders, and pouches, etc.

Sealing equipment closes and seals an individual box that provides a long continuous horizontal or vertical seal. There are several styles of sealers that are unique.

Sealing machines that combine shape, filling, and sealing functions are also available. Some sealing units carry the plastic film horizontally, while others are transported vertically.

Applications of Sealing Machines:

In the chemical, medical, and pharmacy sectors, sealing devices are used extensively. Meat, drinks, cosmetics, electronics, and semiconductors are also manufactured using sealing machines.

End-of-line machines get ready for shipping of the item. Bundlers (also called sleeve wrappers), palletizers, pallet wrappers, plus the conveyor system used to move the goods could be included in this. For the application of labels or printing on the package, extra machinery is used.

Uniform case sealers may be used for production runs of cases of the same size. They can be physically reset between box cases.

Random case sealers are used when each package size differs randomly, such as in order to pick warehouses. The device automatically switches to the box dimension when seen. At lower volumes, random case sealers are more expensive and more costly than uniform case sealers.


Hand held heat sealer machines use heated seal wires which are activated when the seal bar is pressed close. A silicone sealing pad that can withstand direct heat contact is also made from the sealing bar. The sealing bar forces the wire and the film to melt the seal-forming material and mend it.
