Goods that are weighed in store, like fruit and vegetables, use weigh-scale labeling so they can be efficiently marked up with variable information and scanned at a checkout. This can be either self-service, where consumers weigh and label their own produce, or at a checkout or other service counter, where it is done by shop staff. Weigh-scale labels use direct thermal printing on pre-printed labels and have a short lifetime as they are only needed until a cashier scans the item.
Fruit and vegetable labels are often applied directly to edible skins, so both face materials and adhesives must be approved for direct food contact. Labels must stay firmly in place on their journey to the checkout, or the information they provide will be lost.
BPA-free thermal papers
Bisphenol-A has traditionally been used to develop color in thermal papers, including cashier receipts and weigh-scale labels. In advance of upcoming legislation restricting its use, UPM Raflatac has a wide range of FSC™ certified, BPA-free, and phenol-free alternatives available.
