Wahren Ultra - Safe PVDC
The product consists of high-quality PVC film coated with PVDC (Polyvinylidene Chloride) to deliver enhanced barrier protection against moisture, oxygen, and other environmental factors.
This advanced film structure provides excellent thermoforming properties, clarity, mechanical strength, and superior barrier performance, making it highly suitable for pharmaceutical blister packaging applications. Ultra-Safe PVDC film helps maintain the stability, safety, and shelf life of moisture-sensitive pharmaceutical products.
Applications
Ultra-Safe PVDC film is specifically designed for pharmaceutical blister packaging used to individually package tablets, capsules, and other solid dosage forms.
The film is thermoformed to create cavities that securely hold the product and is then sealed with aluminium lidding foil to provide reliable protection from moisture, oxygen, and contamination.
