For permanent marking of products being used indoors and outdoors, choose Avery resistant labels. These silver laser labels are significantly more durable than conventional paper labels due to their strong adhesion and their resistance to water, oil, dirt, UV rays and extreme temperatures (-40°C to + 150°C). Ideal for applying to metal, plastic, painted surface, fabric, polycarbonate and glass, both indoors and outside.Suitable for printing in most laser printers, the excellent print finish on these bright white labels is clear and sharp either in colour or black and white.
