A:AnswerI believe you should have no problem with this product overheating, it does get warm to the touch from the heat strip that seals the bags but that shouldn’t affect the ability of the product to vacuum and seal multiple items in a short period of time.
A:AnswerProbably 5 mm, but I bought an impulse sealer on Amazon for $16 dollars for this very purpose and o prefer it for the pill packs, which I've been doing for about 2 years now
A:AnswerIt has a separate seal button that you can use to seal the mylar bags with. But because mylar bags are smooth, the bags will pinch shut and the air won't get vacuumed out. To vacuum seal mylar bags, I insert the correct size oxygen absorber into the bag and then seal it with my sous vide's sealer or use a hand held iron. Give the bags about an hour or two and they will be vacuumed tight.
