Here are some critical test items, along with relevant standards, test methods, and instruments:
Barrier Properties:
- Water Vapor Transmission Rate (WVTR): Measures the rate at which water vapor passes through the material.
- Standards: ASTM E96, ISO 2528
- Test Instruments: Gravimetric and Coulometric methods
- Oxygen Transmission Rate (OTR): Measures the rate at which oxygen permeates the material.
- Standards: ASTM D3985, ISO 15105-2
- Test Instruments: Oxygen transmission rate analyzers
- Carbon Dioxide Transmission Rate (CO2TR): Measures the rate at which carbon dioxide permeates the material.
- Standards: ASTM D1434, ISO 15105-1
- Test Instruments: Gas transmission rate analyzers
Labthink C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249,ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.
Mechanical Properties:
- Tensile Strength and Elongation: Measures the material's resistance to breaking under stress.
- Standards: ASTM D882, ISO 527
- Test Instruments: Tensile testing machines
- Tear Resistance: Measures the force required to initiate and propagate a tear in the material.
- Standards: ASTM D1922, ISO 6383
- Test Instruments: Tear testers
- Seal Strength: Measures the bond strength between layers of the laminate.
- Standards: ASTM F88
- Test Instruments: Seal strength testers
- Impact Resistance: Evaluates the material's ability to withstand impact forces.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
