Heat Sealers for Film, Bags & Sacks

Impulse sealers or more commonly known as Bag Sealers or Heat Sealers are used for sealing PE, OPP or other heat sealable bags by welding the plastic together. A Bag Sealer is characterized by the length and width of the jaw of the welding wire. for example, the STEP 305HI with jaw length 300 mm and the welding wire is 5mm. There are manual sealers like the STEP 300HI. Automatic Sealers such as the STEP 455AI. A foot operated bag sealer, the STEP 455FI, and a number of variants such as band welders ME-883BS and welding handle. There are sealers where there are welding wires on the upper and lower jaws. This type of configuration is called a Double Solution where the heat is applied from both the top and bottom. It is primarily used for heavy bags, and bags with aluminum foil.
