ILS Impulse Wire

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 Impulse Wire sealing technology employs a single Nichrome wire to create the front seal and side seals around your package. During the Sealing Cycle, the wire temperature is controlled by the Seal Wire Heat Adjust for a fixed amount of time which is regulated by the Impulse Timer. A Sealing Wire Sensor monitors the heat buildup in the wire so overheating and wire breakage during the sealing cycle is prevented. For the larger sealers and custom sizes, individual Seal Wire Heat Adjust controls for the front seal and side seal are used. An Impulse/Constant Heat switch allows the operator to choose which sealing method is best for the particular film being sealed.

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.
