Frequently Asked Questions ?

This can cause discolouration or staining on the surface of the plastic, which can affect the visual appearance of the packaging.

DuPont stain can cause discolouration or staining on the surface of the plastic, which can affect the visual appearance of the packaging. This can make the packaging less appealing to customers and may affect the overall quality perception of the product.

To prevent DuPont stain, it is important to select the appropriate desiccant for the type of plastic used in the packaging. Additionally, using a barrier layer or protective coating between the desiccant and the plastic can help to prevent staining. Conducting compatibility testing before using a new packaging material can also help to identify any potential issues with staining.
