Reheat with saran wrap

I have not used it in an oven... but if I recall the foodservice film will hold up to 265. I wrap hot briskets right out of the cooker before coolering them, or putting them back on for a finish... so wrapping the hot stuff typically isnt an issue. just wear jeresy gloves with xl size nitrile or latexs over them.... so you dont burn your digits to nubs. We have found that gives you the highest touch/dexterity, but still protects you. Heating over the water makes sense for the oven. That way you are not getting the direct heat of the element that would likely compromise the film. Just like putting it in a smoker over a water pan!
