The growing demand for eco-friendly practices has propelled sustainable packaging to the forefront of industry innovation. Manufacturers are increasingly adopting materials that minimize environmental impact, utilizing recycled and renewable resources. However, sustainability must not compromise product protection and shelf life. Rigorous testing is essential to validate the performance of these new packaging solutions.
To ensure the longevity and quality of packaged goods, particularly in the food and pharmaceutical industries, measuring the Oxygen Transmission Rate (OTR) is essential. This test, defined by ASTM D3985, quantifies the amount of oxygen that permeates through a packaging material. Specialized Oxygen Transmission Rate (OTR) Testers are employed for this purpose. These instruments utilize sensors to precisely detect the oxygen passing through a sample over a specified period, providing crucial data for preventing oxidation and maintaining product integrity."
Similarly, the Water Vapor Transmission Rate (WVTR) is a critical parameter for evaluating packaging designed to protect against moisture. As defined by ASTM F1249, this test assesses the rate at which moisture vapor passes through a material, crucial for preventing spoilage. Water Vapor Transmission Rate (WVTR) Testers are used to perform this evaluation. These devices typically incorporate humidity chambers and sensitive weighing systems to accurately determine the moisture vapor transmission, ensuring that packaging effectively safeguards products from moisture damage.
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.
Physical Characteristics such as Tensile Strength, Elongation, Bursting Strength, Puncture Resistance, and Seal Strength are also key factors to be tested.
Organizations like ASTM International and ISO provide standardized testing protocols, ensuring consistent and reliable evaluation of sustainable packaging materials. Many of the instruments used for these tests are designed to comply with these industry standards. These standards enable manufacturers to make informed material selections, optimize packaging design, and confidently deliver products in environmentally responsible solutions.
Continuous research and development of new testing methods are vital to ensure that sustainable packaging meets the evolving demands of product protection and environmental responsibility. Specific examples of sustainable packaging currently being tested include packaging made from mycelium, algae, and plant-based plastics. By prioritizing rigorous testing, the industry can confidently advance sustainable packaging, minimizing environmental impact while maintaining product quality and consumer satisfaction.
