Hot Air Seam Sealing Machine

A Hot air seam sealing machine is a type of sealer that uses heat to seal materials. A seam sealing machine operates by generating a high current impulse for the heater ribbon located on the surface of the device which is used for sealing. The machine provides a fast, simple and reliable way of applying hot melt for sealing and creating a waterproof product.

What is the Purpose of a Sealing Machine?

Hot air sealing machines are used to seal products containing granules, sprays, liquids, powders and more for consumer original equipment and bulk supply shipments. There are also seam sealing machines for garments and other packaging materials like containers, bags, bottles, jars, cartons and boxes. Seam tape machines could also come in a fully automated, semi-automated or manual design that requires do not need operator input, requires little input or heavily depends on the operator.

What Temperature Should Seam Sealer Be?

Seam sealer should ideally be above 60 degrees Farenhites which is a sweet spot that is not too hot or not too cool for material sealing. However, in some cases, the temperature needs to be raised much higher, especially when sealing thicker materials. For some others, it may need to be lowered.

After sealing, it takes approximately 3 to 4 hours to dry completely depending on atmospheric conditions. However, this applies to manual seam sealing machines that do not have an inbuilt dryer.

What Materials can be Heat Sealed?

Heat sealing is used for several applications across the manufacturing and packaging industries. These include PP, PS, IPS, PVC, aluminium foil, PA and board materials. It is also used for material packages like paper, garments, plastics, bottles, jars and more.

Films used for heat sealing applications are manufactured as either single-layered or double-layered. Single-layered surfaces are often materials with adhesive or lower melting point coating while double-layered materials have a higher melting point.
