Testing Gas Barrier Properties of Complex Films-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Testing Gas Barrier Properties of Complex Films Keywords: Complex Film, multi-layer film, gas Barrier Property, Gas permeability test, gas transmission rate test, Edge Sealing, Accuracy Complex films, multi-layer structures made from various materials, play a vital role in modern packaging. Their ability to impede gas transmission is crucial for maintaining product freshness and shelf life. However, accurately testing the gas barrier properties of these films presents unique challenges due to their layered construction. Testing complex films is challenging. Firstly, the influence of Multi-layer. The layered structure of complex films can influence gas flow patterns within the material. This differs from single-layer films where gas transmission is more straightforward. Package edge leakage is another possible challenge. Unsealed edges on complex film specimens can become leakage points during testing. This compromises the accuracy of the test results by allowing gas to bypass the intended measurement path. To overcome these challenges and ensure reliable test results, strict edge sealing of complex film specimens is paramount. This minimizes edge leakage and guarantees gas transmission occurs solely through the film itself. Gas barrier property testers typically employ various methods to measure gas transmission rates through the film sample. Common methods include: 1
