Rebuild Kits 
Did you know ...
that the primary cause of poor seal quality on L-Sealers is the lack of good seal pressure due to burned and worn seal pads and teflon tape?
M-Pak's aftermarket rebuild kits can refurbish your seal jaw to like new condition.  Available for most common L-Sealer brands.
Cross sectional view above shows a typical L-Sealer configuration.  Top bar with nichrome seal wire and lower pressure bar (platen) with silione pad and teflon tape.

Pad Condition
The diagrams to the left show the difference between good and bad seal pad condition and how it effects seal quality.  
With burned and worn teflon tape and silicone seal pads, the molten film normally displaced by the seal wire when it melts/cuts the film against a good pad is not extruded to each side of the wire to form a proper weld bead.  Instead, the wire drops down into the burned/eroded seal pad and no pressure is generated to extrude the film bead.  The result is poor seals, film buildup on wires, cutting difficulty, reject packages, and lost production.

Refurbish your L-Sealer now with our L-Kits.  All you need to give new life to your sealer.  Available for most models.
