Durables labelling materials
PET (polyester) is widely use for durable labelling. UPM Raflatac’s PET White TC 50 is suitable for use on computer hardware, domestic appliances and various electronics, while PET Matt Silver TC 50 may be used on automotive parts or power tools, for example. A clear and thin 12-micron PET overlaminate can be used to protect the labels from wear and abrasion.
Other high-strength labelling materials include Tyvek and Tyvek Brillon, both used for cable labelling, and PE white strong 75.
UPM Raflatac’s RP 37 adhesive provides all the performance required for general applications. Heavy-duty applications involving exposure to high temperatures or chemicals require a durable label face combined with the radiation-cured RC 18 adhesive.
End-users may require that labelling materials have an approval for their durability. Independent testing institutes such as Underwriters Laboratories specialise in setting up durability tests. Labels are applied to particular substrates, exposed to specified liquids and temperatures, and their performance evaluated. When thermal transfer labels are involved, the type of ribbon should be specified and used in the test procedure.
