L-Bar Sealers

Belco L-Sealers feature a welded tubular steel frame and sealing head design to maintain perfect alignment during the sealing process. This unique construction is superior to conventional assemblies that are simply bolted together. This manufacturing process provides consistently strong seals, long machine life and years of trouble-free performance.

Belco L-Sealers with Hot Knife Sealing Technology rely on a set of Mushroom Sealing Knives to seal the film at the proper temperature without creating fumes, smoke and residue common with Impulse Wire sealing machines. Traditional impulse wires operate at higher temperatures to seal and then cut the film while hot knife sealing uses a steel rule cutting blade to mechanically cut the film and the mushroom profile is used to  create a small fin seal on the package. This system utilizes heavy duty cartridge heaters for long life, independent Watlow digital temperature controls and precision thermocouples to exactly monitor and control the side seal and front seal. 

Belco L-Sealers come in a variety of sizes and styles to help you package your product in a quick and efficient manner.


All film manufacturers require sealing machines to control the same three variables in order to make their film seal: Time. Temperature and Pressure. For 60 years. Belco L-Sealers have easily met and surpassed these demands while producing fast. clean. and repeatable seals. 

Available Models

ILS2016HK    ILS2520HK    ILS3022HK    ILS4030HK    ILS5030HK    ILS5016HK   

The sealing operation is safe, fast and reliable. Simply place your product into the centerfold of film, advance both film and product into the seal area and lower the sealing arm. Upon completion of the heat seal cycle, the arm will return to the up position, leaving your product fully wrapped.
