PVC blister film for pharmaceuticals is engineered to meet strict industry standards, with key properties that address safety, usability, and product protection:
Excellent Barrier Performance: It provides a reliable barrier against external contaminants (e.g., dust, moisture, and minor oxygen exposure), preserving the potency, stability, and shelf life of sensitive pharmaceutical formulations.
High Thermoformability: The film softens uniformly under controlled heat, allowing easy formation of precise, consistent blister cavities (various shapes/sizes to fit different tablet/capsule dimensions) during the blister packaging process.
Optical Clarity: Its transparent nature enables clear visibility of the enclosed drug, allowing consumers, pharmacists, and inspectors to check product appearance (e.g., color, shape, integrity) without opening the package.
Good Sealability: It forms strong, hermetic seals with compatible lidding materials (typically aluminum foil or paper-aluminum composites), preventing product leakage and ensuring tamper resistance.
Cost-Effectiveness: Compared to premium pharmaceutical packaging materials (e.g., PET, PP, or PVC/PVDC laminates), PVC film offers a more economical solution while meeting basic pharmaceutical requirements, making it ideal for large-scale drug production.
Regulatory Compliance: Pharmaceutical-grade PVC blister film adheres to global standards such as the U.S. FDA’s 21 CFR, EU’s REACH, and Pharmacopoeia guidelines (e.g., USP, EP). It is free from harmful additives (e.g., heavy metals, phthalates in some formulations) and undergoes rigorous testing for extractables and leachables to ensure no chemical migration into the drug.
