This time in the NEPATA test studio: a double-sided adhesive film with an exceptionally strong adhesive and a glassine paper liner. The aim of the test was to cut precise strips of double-sided adhesive tape from the material.

The task

The master roll is intended to produce double-sided adhesive tapes in widths ranging from five millimetres to five centimetres, with a length of 25 metres per roll. Strong adhesives are considered challenging to slit, as they tend to smear and can build up on the blade.

Procedure and settings

As the material has a liner, a single-sided blade was used. Due to the strong adhesive and to achieve a better overall cutting result, we also used the lubrication system, which automatically coats the blade with silicone oil. We explain in detail which blade is suitable for which material in our slitting series.

The result

As expected, the NEPATA ADWS slitting system handled the task with ease: the double-sided adhesive tapes have smooth, clean cut edges across all widths.
