Sealers accommodate polyethylene and laminated material for packaging and supply applications. Units support small, irregular, or extra-long dimensions for application versatility. In most cases minimum warm up time required. One of the most popular heat sealers is the Impulse sealer, this tool uses heat to essentially melt a small strip of plastic in the bag so it forms an air tight seal. The reason it is called an “impulse” sealer is that the heat it applies is not continuous. Rather, the heat is dispersed in small impulses when activated. The timer on a sealing machine controls these impulses which control the total amount of heat that is applied.
Thicker plastics will need more heat, or more impulses and very thick bags or foil will require a constant heat sealer which provides a constant source of higher heat so you can seal the thicker bags. Thicker bags will take a bit longer to seal as well. The heat is generated through a wire which then heats the sealing element that you close over your bag. Heat sealers are made to last with a Teflon coated sealing surface for durable frequent use. Sealer operates by placing the material you want to seal between sealing bars, pressing the handle down and releasing. Portable Sealers are often used for Commercial, Packaging, Food service, Medical applications, and more. You may need to seal something big or long so they have Long Hand Sealers that accommodate longer length poly bags and thermoplastic materials. Large volume operations will want to look into a foot operated heat sealer to accommodate high volume poly bag sealing for packaging parts, screws, nails, and supply applications. Foot pedal control frees up hands for faster production. Most larger heat sealers will Include a pedestal base, adjustable work table, and adjustable foot control. This can be a real time saver when you are sealing a large amount of packages.
