Medical Test Strips

Polyester film offers unique benefits when used as the substrate for medical test strips:

Inert and plasticiser free: no migration of species to the surface over time.
High stiffness: thinner films retain rigidity when inserted into reading devices.
Dimensionally stable to changes in humidity.
Dimensionally stable to changes in temperature, which can be further improved by subsequent annealing: retain tight registration during strip printing.
Tight caliper control: reliable insertion into reading devices.
On some grades, the film surface can be modified to improve ink adhesion or to make the surface hydrophilic.

We offer a wide range of Melinex®, and Mylar® films that are suitable for medical test strips. These include:

Brilliant white with high opacity, translucent white, matte and glossy clear films
Low shrinkage and ultra-low shrinkage films
Films which are uncoated, primed for adhesion of dielectric ink, or gelatin-coated for hydrophilicity
