Compostable materials are gaining traction due to environmental concerns. To ensure their suitability for packaging food, pharmaceuticals, and everyday items, testing their barrier properties is crucial. These properties determine a material's ability to prevent gas or water vapor from passing through, affecting product quality and shelf life.
To evaluate the barrier properties of a compostable material, two standard tests can be employed:
Gas Transmission Rate (GTR): The test involves exposing the film to oxygen and measuring the amount of gas passing through over time.
Water Vapor Transmission Rate (WVTR): The test involves placing a water-filled cup covered with the film in a controlled environment and measuring the weight loss due to water vapor escaping.
Labthink C403H 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.
Testing biodegradable films is important for understanding their limitations and identify areas for improvement to expand their practical applications.
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!
