As for its size, the actual label size is 60 X 40 mm. But we'd recommend to set the label size on computer program as 56 x 40 mm (default setting of our bonvoisin barcode scale) or 58 x 40mm. So there will be some space around the label, which will display more clearly and not print outside the border.
Generally speaking, the stickiness of label paper can last up to a year, but the time will be greatly reduced if it is exposed to moisture. If the label paper you received has lost its stickiness, please contact us for a replacement.
