The invention relates to an
adhesive label (100) for traceable labeling of a reusable food container (15). The
adhesive label (100) is structured in
layers and comprises a first
adhesive layer (11), a shrink film (12), a second adhesive layer (13), and a
thermal printing paper (14), wherein the
thermal printing paper (14) is configured to dissolve at least partially when exposed to a washing solution (17) at a temperature of 63°C to 67°C, in particular 65°C, for an
exposure time of 120 s to 180 s, in particular 150 s, and the shrink film (12) is configured to shrink when exposed to a temperature of 63°C to 67°C, in particular 65°C.so that the adhesive
label (100) can be removed from the food container (15) without leaving any residue. Furthermore, the invention relates to a method (200) for traceable labeling and washing of a reusable food container (15) comprising the steps of: providing (50) the food container (15), filling (51) the food container (15) with products, providing (52) an adhesive label (100), wherein the adhesive label (100) is releasably laminated onto a
release liner (10), printing (53) the adhesive label (100) with product-related information, peeling (54) the
release liner (10) from the adhesive label (100), applying (55) the adhesive label (100) to the food container (15), successively removing (56) the products from the food container (15), cleaning (57) the food container (15), and applying (58) a washing solution to the applied adhesive label (100). (17) at a temperature of 63°C to 67°C, in particular 65°C,for an
exposure time of 120 s to 180 s, in particular 150 s, until it detaches completely from the food container (15).
