Products Description
OPA/AL/PVC is a common structural configuration of this cold forming foil, and each layer of material has its specific function:
OPA (Outer Layer – Oriented Polyamide): Provides excellent mechanical strength and toughness, withstanding stretching and impact during forming while offering a high-quality surface for printing.
AL (Middle Layer – Aluminum Foil): Delivers an exceptional barrier against oxygen, moisture, and light-essential for extending drug shelf life and protecting sensitive formulations from environmental factors.
PVC (Inner Layer – Polyvinyl Chloride): In direct contact with the medication, this layer ensures reliable heat sealing and maintains package integrity.
This synergistic construction makes Alu-Alu cold forming foil the preferred choice for blister packaging, particularly for pharmaceutical products requiring protection from moisture, oxygen, or light. By utilizing this high-performance material, drug manufacturers can safeguard product quality and efficacy while meeting the stringent demands of the pharmaceutical industry.
Products advantages
Independent Unit Sealing: Each cavity forms a sealed unit, ensuring that medications in other blisters remain unaffected when one dose is removed-maintaining integrity and hygiene.
Superior Triple Protection: The aluminum layer provides an complete barrier against moisture, oxygen, and light, effectively extending drug shelf life-particularly for solid dosage forms such as tablets, capsules, and powders.
Enhanced Market Appeal: The clean, premium appearance of Alu-Alu packaging elevates product presentation and strengthens pharmaceutical brand competitiveness on the shelf.
