Food Packaging Testing Solutions Extending Shelf Life

The processed food industry is heavily reliant on packaging to maintain product quality and ensure consumer safety. Packaging serves as a crucial barrier, protecting food from external factors that can accelerate spoilage, such as moisture, oxygen, and contaminants.

To achieve optimal product shelf life, packaging must be meticulously designed and tested. A key consideration is the packaging's barrier properties. For instance, water vapor transmission rate (WVTR) measures the amount of moisture passing through the packaging, while oxygen transmission rate (OTR) indicates the amount of oxygen that permeates the material. These parameters are critical in preventing spoilage caused by oxidation, moisture, and microbial growth.

Testing the packaging's ability to protect against organic compounds is equally important. These compounds, responsible for flavors and aromas, can migrate through packaging materials, affecting product quality. While WVTR and OTR testing methodologies are well-established, evaluating the transmission of organic compounds remains a complex challenge. However, recent advancements in analytical instrumentation have made significant strides in this area, enabling more precise measurement of these critical factors.

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.

In addition to barrier properties, packaging must also withstand the rigors of the supply chain. Tests for factors like seal integrity, puncture resistance, and impact resistance are essential to ensure product protection during transportation and storage.

As consumer demand for high-quality, longer-lasting food products grows, the development of innovative packaging solutions becomes increasingly critical. By investing in rigorous testing and analysis, the food industry can optimize packaging design, extend product shelf life, and ultimately deliver superior products to consumers.

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!
