Unwind directions dictate how the rolls of labels are produced so that the labels are facing in the right direction on the roll at the time of application. It is usually only important to specify an unwind direction when the labels are going to be machine-applied to end products, and it ensures that the applicator is receiving and dispensing the labels in the right direction on the containers (e.g., bottles or jars) they're being applied to. If you're intending to hand-apply each label, unwind direction usually is not important. See this chart for more details.
