I got a plastic bag heat sealer...the heat sealer heats up in the middle more than the sides...how can i fix that?

Question edited for a lot more clarity.
Question moved from Vacuum Cleaners to Vacuum Sealers.

You need a new seal bar, it is heating unevenly.

Could be the heating element (wire that gets hot enough to melt plastic) is going bad, how long have you been sealing bags with the unit? If you have used it for some time there is the possibility of build up plastic/residue on the the wire or the surface that actually comes in contact with the bag as I would suspect there is a coated surface the element heats up as opposed to the element / wire coming in contact with the plastic itself!

The same thing happened to mine and I found a really,really inexpensive way to resolve it. I don't use original foodsaver bags and I found out that their thickness might not be detected correctly so it won't vacuum. To compensate for this, I used an ordinary piece of notebook paper. I cut it to a size of 4 1/2" by 1 1/2". I set the long side in the middle of the liquid catching tray and let it lean back towards the heat strip. Make sure it doesn't cover the heat strip or it won't seal. Now I inserted the bag as the directions say, close and lock the top, and it vacuums and seals perfectly.

An impulse sealer heat-seals objects by sending high current on impulse to a heater ribbon, equipped on the surface of the heat-sealing blade, to generate heat that enables thermal-sealing through thermal conductivity. The section to be sealed is placed between the heat-sealing blades, pressed and thermal-fused when current and heat are delivered on impulse through the heater ribbon. After the current stops the seal remains under pressure to cool and to give it a clean finish.

Heating Element / Wire - After heavy use of the vacuum sealer, it is natural for the heating element to break. The amount of seals per sealing wire is dependent on your timer setting, how often you use your vacuum sealer and how thick your vacuum bags are. When you replace the heating element, we usually recommend you replace the sealing strip as well. Different machines have different sizes of heating elements but we carry five stock elements.

place the end of the roll just past the wire heating element into the sealer and press and hold the lid closed until the cycle finishes. (I usually do this twice in a slightly different place). Remove the roll and cut the plastic back far enough into the roll for the bag you are going to fill. Leave enough space to seal the bag after you have filled it. Seal the filled bag according to the instructions.

Hi,
No, the heating strip is actually a wire that get s warm the do the sealing...when the wire breaks there is no more heating and there is no way to repair that wire...

the function that seals the bag after the vaccum process (melts the plastic to itself) Hope this helps
