Curved Surface Adhesion Test
Brother DK film labels are specifically designed so that the labels will
stick to most cylindrical surfaces used within the laboratory and medical
sectors*.
Curved Surface Adhesion Test Procedure
Brother DK film and paper labels were attached to test tubes of various materials
and sizes, and left for approximately 30 minutes. The labels were then checked for
their ability to stay affixed to each particular surface.

= Sticks perfectly to the curved surface
= 5mm to 10mm of the label’s edge springs back
= Does not stick to the curved surface

For labelling curved objects with a small diameter, we recommend the use of Flexible ID TZe label cassettes.
Strong Adhesion Test
Brother DK paper and film labels are both supplied with a strong adhesive
to ensure that they remain stuck to most common surfaces.
Strong Adhesion Test Procedure
To test the adhesive strength of Brother DK film and paper labels, 25mm wide
labels were affixed to a variety of surfaces and left for 30 minutes.
The adhesive strength was tested by removing the label at an angle of 180
degrees. This testing method complies with Japanese Standard JIS Z0237 testing
for adhesive tape.
Strong Adhesion Test Results
The table shows that an adhesive strength of at least 11 Newtons was maintained
with most materials, indicating sufficient adhesive strength against most common
materials.
