Unprinted Blister Foils are manufactured by Wahren. These foils are produced using high-quality pharmaceutical-grade aluminium foil coated with heat-seal lacquer, designed specifically for blister packaging applications.
The foil provides an excellent barrier against moisture, oxygen, light, and contamination, ensuring maximum protection for pharmaceutical products. The unprinted surface allows flexibility for plain packaging or secondary printing/labeling, while maintaining consistent sealing performance with PVC, PVDC, Triplex, and other blister films.
Unprinted Blister Foils are widely used in pharmaceutical blister packaging to seal formed blister cavities containing tablets, capsules, and other solid dosage forms.
