Light and UV Protection for Sensitive Formulations

Some formulations degrade under light before they degrade under moisture, which changes material selection.

Options for protection

• Aluminum foil laminates for complete light blocking
• Metallized films for light and UV blocking while remaining printable
• Opaque pigmented structures where print is the priority

What to check

• Whether the requirement is full blocking or reduced transmission
• Whether the pack must still show the product
• Whether a clear region can be combined with a protected region
