Es muy fácil dañar las bolsas y es muy complicado limpiar los elementos que se calientan el plástico que se pegaNo recomendable no es preciso y difícil mantenimiento

We purchased this because of Howard W.'s review, in which he states that he is using it for the gold retort canning bags (distinct from Mylar) for food storage. Our JVR chamber vacuum sealer - while an excellent machine overall - is seriously marginal for sealing retort bags, as the built-in seal heating time (even with the custom 'retort bar') cannot be set long enough for a truly reliable seal.. Why JVR could not build an extra second or two of seal time into the machine software is just beyond me.Unfortunately Howard's review did not state tested times or temperature for the retort bags -* 150 DEGREES FOR 4 SECONDS * creates - once cool - a seal that you literally cannot get apart with pliers (and I've tried); the bag rips to shreds before the seal ever lets go. Note that full warm-up time on the machine is critical - I like the feature where the green 'heating' light goes out and the red 'ready' light stays on once temp is reached.As another reviewer commented, put a cutting board underneath - even with the little stand-off legs, this machine is HOT.We use the 80 micron weight retort bags because the 100-weight was even worse in our JVR, but will likely go up to the 100 microns now (not that you can really tell any difference visually) as I'm certain this sealer will work just as well on them.We're very excited to have this machine because failing seals during pressure canning processing was our number one issue with retort canning. Like others have found, the knob hardly feels like precision German engineering - the Chinese still have a ways to go. But the machine works just fantastic for our purposes and we're definitely going to expand the range of foods which we retort can, now that we can get 100% reliable long-term seals..

I purchased this item to provide a secondary seal to retort pouches which I use for pressure canning. These are the multi layer generally gold colored pouches SPECIFICALLY DESIGNATED RETORT POUCHES. Not ordinary mylar pouches. My chamber vacuum sealer, a LEM Max Vac Pro will just barely do this, and requires multiple applications of the seal bar. I was using an ordinary iron for a secondary seal, and to work properly I needed to iron both sides in a process that wasn't very controllable. The problem with retort pouches is pressure inside the pouch as the pressure canner cools. The contents of the pouches do not cool as fast as the water in the canner cools. This results in the pouches inflating and building pressure. This limits the amount of food you can place in these pouches because you need considerable expansion room, and also puts stress on the seal because which is still hot/warm, and so in it's weakest state. The wide multi groove heat seal with heat applied on both sides at once looks like it will make a much stronger seal, probably stronger than the factory weld... I can't tear it apart once cooled. This solves ONE of my problems.....the seal. I'm developing a method of holding the pressure canner at 15 psi after taking it off the heat until everything cools off, using air pressure, and this will solve the volume issue. As it is you have to use a large pouch for a small amount of food.

Took almost 25 days to deliver. Returned the goods as it is fluctuating in temperature setting. And now 10 days after return no refund yet.

Buena herramienta en su calidad pero calienta lo suficiente y se apaga , tardo en graduarla manualmente , me detiene el trabajo y es desesperante
