The Sealing Edge System

We spent several years finding the best sealing edge cover since it is one of the most important parts of every sealer - without it you do not have a workable sealer. The sealing edge cover allows the transfer of heat and pressure to the plastic without sticking to the plastic after the seal is completed.

Good heat transfer is due to aluminum - aluminum contact and teflon coating.
*To replace channel loosen only (do not remove) hold down screws. Then slip channel off between stripper rails. Slip new channel into place and tighten hold down screws.

Teflon is the best single sealing edge anti-stick material available. A dual anti-stick system does exist which provides significantly better long term operation. A microscopically thin coating of silicone does the trick.

A couple of quick swipes of silicone rag to teflon coated sealing edge every day does it.

Plastic Bag Sealer Operating Instructions

Three variables are involved in sealing plastic bags and films:
Temperature	Time	Force Between Hot Bar And Plastic Film

30 years of experience has shown that the time and force factors for most operators using hand held sealers are fairly constant which leaves temperature as the main variable.

		Thus For:
Fig. 1		Thin bags & films from 1-2 Mils thick Keep force 8 - 10 lbs. Time 1 second & set temperature as shown in Figure 1.
Fig. 2		Medium bags & films from 3-4 Mils thick Keep force 8 - 10 lbs. Time 1-1/2 seconds & set temperature as shown in Figure 2.
Fig. 3		Thick bags & films from 6-10 Mils thick Keep force 8 - 10 lbs. Time 1-1/2 seconds & set temperature as shown in Figure 3.

DO . . .	DON'T . . .
Set the temperature control at the lowest position that will give consistently good seals with a force of 8 - 10 lbs. and time 1 - 2 seconds.	Try to cut the sealing time to less than 1 second by raising the temperature. Inconsistent and weak seals will result and the high internal temperatures will reduce the life of the sealer.
Keep the Teflon sealing edge clean and never scrape with a hard, sharp object. Use with adequate ventilation. Vapors may be emitted from some plastic film material when seals are made.	Set the temperature control past the high position for 6 mil materials. Thick materials require time (2 seconds) for the heat to soak through. Excessively high temperatures for short periods will simply melt the outside surface of the first layer of film and will not seal it to a second layer.
	Run the temperature control past the high position to the stop since it will materially shorten the operating life of the unit.
