Testing Biodegradable Film Barrier Properties

Product catalog summary
Introduction
Biodegradable plastics are increasingly popular due to environmental concerns. Testing their barrier properties is essential for their use in packaging food, pharmaceuticals, and everyday items. These properties affect a material's ability to prevent gas or water vapor from passing through, impacting product quality and shelf life.
Testing Methods
  • Gas Transmission Rate (GTR): This test measures the amount of gas passing through a film over time. The Labthink C106H Gas Permeability Test System, based on the differential pressure method, is used for this purpose. It conforms to international standards such as GB, ISO, and ASTM.
  • Water Vapor Transmission Rate (WVTR): This test involves measuring the weight loss due to water vapor escaping from a water-filled cup covered with the film. The Labthink C306H Water Vapor Transmission Rate Test System, based on the infrared sensor method, is used for this test and conforms to ASTM F1249 and ISO 15106-2 standards.
Findings
The full-starch biodegradable film showed excellent resistance to oxygen but poor water vapor barrier properties. This indicates its suitability for packaging dry products but limitations for products needing moisture protection.
Recommendations
To improve the film's performance, modifications such as adding thermoplastic starch or nano-reinforced montmorillonite are suggested. These can enhance barrier properties, moisture resistance, and mechanical strength while maintaining biodegradability.
Conclusion
Testing biodegradable films is crucial for understanding their limitations and identifying improvement areas to broaden their applications. As demand for functional packaging grows, testing methods are evolving for comprehensive evaluations. Labthink encourages collaboration with packaging industry companies for quality control.

Testing Biodegradable Film Barrier Properties-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Testing Biodegradable Film Barrier Properties Biodegradable plastics 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 full-starch biodegradable film, 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. Labthink C106H Gas Permeability Test System is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at different temperatures. The test system conforms to GB, ISO, ASTM and other international standards.
