Tropical Foil is manufactured by Wahren. This high-barrier laminate is specially designed for tropical blister packaging, providing superior protection for pharmaceutical products exposed to high temperature and humidity conditions.
Tropical Foil is typically used as an additional protective layer over conventional blister packs, creating a secondary barrier that safeguards the product against moisture, oxygen, light, and environmental contamination. The laminate structure generally consists of PET / Aluminium Foil / PE or other polymer layers, ensuring excellent mechanical strength, sealing performance, and durability.
This packaging solution is widely used for export-oriented pharmaceutical products, especially in regions with challenging climatic conditions.
Tropical Foil is primarily used in pharmaceutical blister packaging as a protective overwrap for blister packs containing tablets and capsules.
Typical applications include:
Pharmaceutical blister packs requiring enhanced barrier protection
Export packaging for tropical and high-humidity regions
Moisture-sensitive pharmaceutical formulations
Long shelf-life pharmaceutical products
High-potency drugs requiring extra protection
