I am still confused about the clarification on the different sealing temperatures. Increasing the temp per the vendor recommendation is okay but I find some inconsistencies here:Is the MDK pouch material ratio PA/PE higher for the Irrigation tubing only as all other pouches ( WBC, WJC) keep the same sealing temperature?If the MDK film has a little higher ratio of PA- how higher is it, and is this affect the pouch quality? Tracie- please provide an input !I am sorry I keep asking questions , but I just want to make sure the change of the pouch supplier is validated appropriately so we can avoid any sealing issues down the road since JY plan to have MDK as a primary supplier.
