Tensile Properties
Tensile properties of plastic films can help characterize their suitability for use in medical packaging.
Gelbo Flex Crack Resistance
Good flex crack resistance will reduce the propensity of the package developing holes during the distribution cycle thereby destroying the package integrity.
Tear Strength
Tear strength may be measured by using an Instron® tensile tester or an Elmendorf tear tester.
Microbial Barrier
Microbial Barrier is the property of medical packaging substrates to resist the passage of microbes.
Corner Thickness Measurement
Corner Thickness Measurement is a non-destructive test performed on flexible or rigid trays that have been produced by thermoforming.
Puncture Resistance
Puncture resistance of substrates can be measured using the Instron® testing system, the Spencer impact method or the Dart Drop Test.
Coefficient of Friction
Coefficient of Friction (COF) is measured using a friction tester. Friction may be measured film-to-film or film-to-metal depending on the situation.
Smoothness
The Sheffield smoothness of a substrate is calculated by measuring the rate of air flow over the surface of the sheet.
Ink Adhesion
Ink adhesion may be evaluated using ¾-inch wide Scotch® brand 600 adhesive tape, placing the tape firmly over the area to be tested and removing it quickly at a 180 degree angle.
