    • A washable label (100) may comprise a heat-shrinkable layer (10) and a heat-activatable layer (20). The label (100) may be attached to an item (ITE1) by a method comprising: heating a portion (21) of the heat-activatable layer (20) by intense visible or infrared light (LB1) so as to transform the surface of the heat-activatable layer (20) from a non-tacky state to a tacky state, and attaching the label (100) to the item (ITE1) when the surface of the heat- activatable layer (20) is in the tacky state, wherein the intensity of the light (LB1) is selected such that spatially averaged temperature (T 10 ) of the heat- shrinkable layer (10) remains lower than the threshold shrinking temperature (T THR ) of the heat-shrinkable layer (10). The label (100) may be easily separated from the item (ITE1) by heating the label (100) such that shrinking of the heat-shrinkable layer (10) peels at least a portion of the label (100) away from the item (ITE1).
    • 可洗涤标签(100)可以包括热收缩层(10)和可热激活层(20)。 可以通过以下方法将标签(100)附接到物品(ITE1):包括:通过强烈可见光或红外光(LB1)加热可热激活层(20)的一部分(21),以便将 所述热可活化层(20)从非粘性状态到发粘状态,并且当所述可热活化层(20)的表面处于粘性状态时,将所述标签(100)附着到所述物品(ITE1) 其中选择光强度(LB1),使得热收缩层(10)的空间平均温度(T10)保持低于热收缩层(10)的阈值收缩温度(TTHR)。 标签(100)可以通过加热标签(100)而容易地与物品(ITE1)分离,使得热收缩层(10)的收缩将至少一部分标签(100)剥离远离物品 ITE1)。
