How does an impulse heat sealer work?
Impulse heat is the use of a heat spike governed by time “heat time” followed by a cool down period “cool time” during which the seal jaws remain closed. This cool down period allows the molten plastic in the seal area to cool and reset under pressure providing consistent maximum seal properties. The bond that is created during the “cool down period produces a very strong seal with excellent visual apprearance. • Why should I vacuum seal my product? To prevent moisture contamination, extend shelf life, or minimize storage space. • Why should I use Modified Atmosphere packaging (MAP) Nitrogen purge? If you are packaging a product where the shelf life of the product can be improved by flushing the bag with gas, such as in packaging fresh foods or coffee. Electronics and chemicals may also benefit from this process to remove moisture and harmful vapors from the bag, decreasing product exposure to corrosion. • Why is a “clean, dry air supply” necessary? It is necessary to maintain the warr
