Only laboratory and industrial tapes are available as printing materials. This makes it impossible to mix them up with so-called office tapes. The basic durability and other properties have been tested by VTT Technical Research Centre of Finland. The tested characteristics are light resistance, cold resistance, heat resistance, autoclave processing, solvent resistance and abrasion resistance. The test results of Kroko labels are excellent across the entire product range. Kroko labels are also able to withstand liquid nitrogen, and their peel strength ASTM D 3330 according to the A method is one of the best available on the market, if not the very best.
