H₂S Loss through Nalophan™ Bags: Contributions of Adsorption and Diffusion

Table 5

Diffusion coefficient of H₂S over time in a Nalophan bag stored at a temperature of 23°C and a humidity of 20% and 60%, respectively. The bag tested was without any film inside (B-no film) and with the film inside. The surface of the internal film sheet was equal to 1900 cm² (B-film 1900), 2580 cm² (B-film 2580), and 3520 cm² (B-film 3520), respectively.
