PVC (Polyvinyl Chloride) plastic film is often used in the packaging of medical blister packs for several reasons:
1. Barrier Properties: PVC provides an excellent barrier against moisture, oxygen, and other environmental factors. This helps protect the enclosed medication from degradation due to light, moisture, or air, ensuring the product remains stable and effective until its expiration date.
2. Chemical Resistance: Medical blister packs made of PVC can withstand exposure to many common disinfectants and solvents, making them suitable for the packaging of various types of medications that might require sterilization or cleaning.
3. Durability: PVC is known for its toughness and durability, which makes it less likely to tear or puncture during handling or transportation. This ensures that the contents within the blister pack remain intact and secure.
4. Sealing Capability: PVC films can be easily sealed with heat or adhesive to create a hermetic seal around the blister cells, preventing any external contaminants from entering the package.
5. Printability: PVC films are highly printable, allowing for clear and detailed labeling of the medication's name, dosage instructions, expiration date, and other important information. This enhances patient safety by providing clear instructions on how to take the medication correctly.
6. Cost-Effectiveness: PVC packaging is relatively cost-effective compared to other materials, especially for large-scale production of blister packs. This makes it a practical choice for pharmaceutical manufacturers looking to keep costs down while maintaining quality standards.
7. Customizability: PVC films can be produced in various thicknesses, colors, and finishes, allowing manufacturers to tailor the packaging to specific needs or preferences. For example, a matte finish might be preferred for better readability, or a specific color could be used to denote the type of medication inside.
