I know that some people have investigated which tapes do well in low-temperatures, but I have found that most good quality packing tapes will survive the process and keep the plastic sheeting in place. This is in contrast, of course, to low-oxygen treatments where a good seal for the barrier films require a heat sealer of some type.<o:p></o:p></p><p class=MsoNormal>Sincerely,<o:p></o:p></p><p class=MsoNormal>Rachael<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Rachael Perkins Arenstein<o:p></o:p></p><p class=MsoNormal>A.M.
