Product Description:
This specialized multi-layer film is designed to prevent fogging and moisture ingress in blister packs for oral solid dose medications (e.g., tablets, capsules). Combining PVC, PE, and PVDC, it integrates anti-fog agents and high-barrier properties to ensure clarity and stability in humid environments. Ideal for tropical climates or high-humidity storage conditions.
