"The main attribute of the various units described on this webpage is their portability. All of these sealers
can be used across long distances on a shop floor with a simple addition of an extension cord."
Using a heat sealer to achieve a proper seal of one's storage bags is critical to the overall effort in storage.
To test the seal of the bag, apply a seal to two layers of your bag, if seal can be pulled apart, your seal is not secure.
Shown here are the two types of hotjaw sealers. On the left is the
*PTFE Flouropolymer COVERED unit which produces a narrow seal but will work with polyethylene. On the right is the new and improved *PTFE Flouropolymer COATED unit with its non-stick surface, an excellent unit for large foil and mylar® bags or covers.
Most common heat sealers deliver a seal of approximately 2 mm (less than 1/10 of an inch). This 6-inch "constant heat" clam-type Hot Jaw unit makes a strong, clean 9/16" seal.
The jaws are sufficient to close any type of heat sealable multi-layer* structure. Any size of bag can be sealed using this heat sealer.
Here we see a comparison of the Hot Jaw heat sealer vs a conventional impulse sealer. The Hot Jaw produces a 9/16 inch seal
while most others produce a 2 mm seal.
The items pictured at right are packaged in a clamshell style package. Ocassionally, we see IMPAK's HotJaw™ CLAMP sealer referred to as a clamshell sealer, usually in a You Tube video. Our engineers are actually UNABLE to close a clamshell package with our CLAMP sealer.
"They do work very well with Mylar® and aluminum foil barrier bags."
IMPAK has two similar but slightly different types of sealers that can be referred to as "Hot Jaw." Each should be evaluated carefully and chosen subject to your specific need.
Not only is the Futura "bakelite" plastic housing subject to cracks and chips if dropped, but it also lacks the *PTFE Flouropolymer non-stick coating ESSENTIAL for many thermoplastics, is also dramatically overpriced at 60% higher than our better quality units.
