Review: Great sealer. Best I have found for the price. - Like a lot of people, I was interested in putting away some food for long term storage. I researched various methods of doing so, as well as purchasing pre sealed items from various distributors. First thing I discovered was the prices are outrageous in terms of pre packaged dry goods. And the second, is that people can sure come up with creative, complicated ways to complete a simple task. This sealer looked like just the thing I needed to do things myself the easy way, and I was right. It is a very simple operation. Put bag in bucket. Pour food in bag, drop in an oxygen absorber, use this sealer to seal the bag, leave the lid off of the bucket overnight to ensure you have a good seal in the morning, then put the lid on. The savings over the cost of paying someone to do this for you and ship it to you, will cover the cost of this sealer in a very short amount of time. The sealer is very simple with only a high and low setting. It has a very generous cord length which is helpful when you are moving around and filling multiple buckets. This sealer puts a very good seal like at the bottom of most chip bags. Much better than a single line seal. It is of sturdy construction and the cord is also pretty heavy duty. Certain to last many years. It can also be used for re sealing any mylar bags such as potato chip bags etc allowing you to put a factory like seal on used products and keeping food fresh longer and saving money. A very useful product, giving a quality, factory seal you can be confident in. Easy to use. Hi setting seals heavy duty bags, and Low does a great job resealing any thin things like chip bags.
Review: The best professional sealer, recommended by desertcart seller - I'm an desertcart seller, and I use this to seal jewelry boxes in poly bags, to send to the FBA, fulfilled by desertcart warehouse. I burned out 2 generic impulse sealers. The impulse sealers take longer to seal and wait. I will never go back to impulse sealers. This sealer works in 1 second. Its incredible. If you are using it to seal poly bags, this is my advice. When I first used it, I set it on high, since this was what I was accustom to on other sealers. The high setting melted the plastic, and I had to use the edge of a pair of scissors to scrape it out of the grooves. I turned it off, and then later came back to finish the job. I admit, I was first disappointed at the melting plastic on the high setting. However, to my surprise, after a second attempt, and only turning on to let it heat up for 5 minutes on the low setting, it didn't melt the plastic off. It was a dream come true! And I only had to press down for 1 second. If you hold down too long on the low setting, it will melt the plastic off the edge. I prefer to cut the edge off. Its less toxic and will keep your machine cleaner by not allowing it to heat too high and melt the plastic material. I am going to try to seal the thicker metallic bags for coffee. I am so impressed with this machine. It feels so secure, sturdy, and I don't think I will be able to burn it out. It also sped up my FBA packaging time a lot. I admit, its extremely fun to seal bags with this machine, I caught myself smiling the whole time. This is the get rich quick desertcart sellers sealer! Love it, a million stars!

## Questions & Answers

**Q: Will this work on "foodsaver" type bags?**
A: Sure, but probably best on the low heat setting.

**Q: how do you get the excess air out of the mylar bags?**
A: Don't seal it completely inn one shot. Add 02 absorber. Create a slight angle to half way. Then another from opposite side. Squeezemost air out. Then final seal. I do this whole operation in just two seals. The angle is slight in order to reuse bag if possible. But itty is an angle. Some preppers say I'm wasting space for food in an already expensive bag and that the o2 absorber will do the rest. But this is what i do. To each their own. I know this is an old post but no one else said it. To each their own

**Q: This closes aluminum bags?**
A: Yes

**Q: Can this bond typical bubble wrap together?**
A: Yes

### ⭐⭐⭐⭐ Works Well
*by M***E on March 9, 2022*

I used this sealer to form a good seal around the edges of a 6mil thick sheet of Polyethylene (PE) which covered a large slab of Styrofoam used as an insert for a hot tub cover. The Styrofoam absorbed moisture from the hot tub and had to be dried out and recovered with PE. The sealer formed a tight seal. There was a lot of trial and error in figuring out the right method in using the sealer. I used the hottest setting and applied the sealer to the PE for only a few seconds. Any longer and the PE would melt too much damaging the seal. Any shorter and the PE would not melt enough. After forming a seal at one place along the PE edge, I would move the sealer to the end of the prior seal and make another seal. I would do this to form a continuous seal for several feet. One review suggested using a rheostat to adjust the voltage to the sealer. But, this did not work. Only the full heat setting (heat to both halves of sealer) worked. Just have to know how long to apply the sealer to the PE to form a good seal. This sealer was pricey, but I could not find any other similar hand-held type of sealer to fit my needs. This device is sturdy and heated uniformly across its width. Very important.
