One
of the most beneficial machines in the packaging industry, heat sealing
machines are used to seal containers, pouches, bags, boxes, cartons,
tubes and trays filled with products. These machines are used to pack
almost all products right from food and confectionery to medicines, from
industrial goods to beverage industry. Fully and semi automated heat
sealers provide a cost effective sealing solution and help to increase
the operational efficiency. The process involves heating the
thermoplastic film or sheet at a specified temperature and
simultaneously applying pressure for proper sealing. These machines will
vary according to the material being sealed.
Impulse heating, continuous heating, ultrasonic heating and dielectric
heating are are by different machines depending on the kind of
thermoplastic being sealed and the type of heat sealer being used.
