Heat sealers are used to create airtight seals for packaging and other kinds of thermosealable plastic. Heating elements are an essential component of these devices, as they create a seal by transmitting heat, in addition to cutting the packaging being sealed.
These heating elements are always used in conjunction with a heat sealer. As heat sealers can create airtight seals that will contain solids as well as liquids, they are very versatile. Heat sealers are used across many different industries, including home businesses (sealing food products within packaging, for example) and can seal many different materials, including anti-static and polyethylene.
Different heating elements are designed to be used with specific models of heat sealers, and the size of the heating element will vary accordingly. Compatible heat sealers are listed in the details for each heating element. Many heating elements also feature electronic timer control, which makes repeated use more convenient.
