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

DuPont Teijin Films offers a wide range of Melinex®, Mylar® and films which 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
