KF-Constant Heat Bag Sealer for Mylar Bags 2 Heat Settings, Black

Works exactly as described in the instruction paper. We need it on high and in 3-10 seconds max the mylar bags are sealed perfectly. This item saves me a lot of time, instead of using a curling iron or any other heating device.

This sealer works like a commercial sealer. I wanted this product to process mylar bags of food and I wanted to make sure the bags were sealed properly. Many people use cheap flat irons to seal their mylar bags, but this sealer provides about 4 seal lines that look like the seals on food you get in the grocery store. My bags look so professional! This sealer seals both the top and bottom of the bag at the same time. I'm really impressed with the heat output and how easy this sealer to use. I recommend it if you're a prepper!

Works great for Mylar, if you’re not heating enough or melting the bag just adjust between low and high and adjust the amount of time you’re holding it closed for. For me, warm it up on high for about 5 minutes and seal for 7-10 seconds. If it gets too hot after a long time I’ll set it to low for a while.

This unit works fine but it needs a holder or cradle to operate. Where can I find this cradle? I imagine that it is foot operated.

Can I say wow. Should have bought you looonnnngggg time ago to seal our coffee bags. Its perfect, 3 second each bag able to rush through larger order batches. Thank you for a reasonable price and quick shipment. Our bags are 5.4 mil gusset bags and this will do the job, quick and I mean quick. Do only into 3 seconds on high you'll be satisfy.

It looks great in principle. I got it, plugged it in and then tried to seal my bags. It became frustrating and took way too much valuable time. I had to prop it open with a ball of aluminum foil each time I wanted to use it, place my bag in, take out the aluminum ball and hope my bag was in the right spot. I started looking at other crimp sealers and they sit in an open position then you close it. I don’t know if this thing is broken or this is how it is. For me, it’s useless when I’m trying to do things efficiently. I’m going to try to return it and then buy a new one. Very disappointed.

These work great. Let them heat up about 5 minutes, you press the bag for about 4 seconds, and it is sealed. The bags get very warm where the seal is, just let it cool off before messing with the bag again, seriously, or you'll mess it up. I do wish I had bought the wider one, as my bags are well over 6" wide, but doing it twice is not a big deal and works great.

Four stars vice five since it seems pretty spendy for what it is, but it works like it should, and is far superior to an iron. Great seals every time.
