Since the labels are active and contain biochemical components, they can be damaged by temperatures that can affect complex protein systems. There is no minimum shipment or hold temperature. Shipments may be delivered by refrigerated carriers during times of the year and to geographical locations where they is some risk of exposure to damaging temperature conditions. In some instances, thermally protected packaging may be selected by our shipping department to protect the labels.
All product is subjected to deep freezing prior to shipment as a protective precaution.
The labels should preferentially be stored frozen. Tests indicate stability at frozen temperatures for up to six months. Activation below this temperature may result in some small percentage fracturing of the permanent liquid seals of the labels. Please consult your sales representative for low temperature activation, as specialized activation equipment or other means may be used to overcome difficulties with low temperature activation. Once applied, there is no low temperature limitation.
