Blister packaging is one of the most common forms of modern pharmaceutical packaging, and PTP (Press Through Packaging) aluminum foil is a key material in this packaging type. Due to its excellent barrier properties, safety, and convenience, PTP aluminum foil plays an important role in the pharmaceutical industry.
Common Materials for PTP Aluminum Foil:
The primary raw material for producing PTP aluminum foil is industrial-grade hard pure aluminum foil. Common alloy types include:
8011 Aluminum Alloy: Known for its excellent ductility, corrosion resistance, and sealing performance, making it the most commonly used aluminum foil material in pharmaceutical packaging.
8021 Aluminum Alloy: Offers superior oxidation resistance and moisture barrier properties, making it ideal for pharmaceutical packaging that requires high barrier performance.
8079 Aluminum Alloy: Features high strength and excellent rupture resistance, suitable for packaging applications that require higher mechanical strength.
Structure of Pharmaceutical PTP Aluminum Foil:
Protection layer (OP), outer printed layer, aluminum foil base material (AL), inner printed layer, adhesive (VC), etc.

Performance Advantages of Pharmaceutical PTP Blister Foil:
1. Barrier Performance: PTP blister foil has excellent moisture and gas barrier properties, maintaining the efficacy and stability of the pharmaceutical products.
2. Protection of Medication: The foil serves as a protective barrier, preventing physical damage, contamination, and tampering of medications.
3. Unit Dose Packaging: PTP blister foil allows for unit dose packaging, with each dose sealed individually to ensure accurate dosing and hygiene.
4. Customizability: Foil sheets can be customized in size, shape, and design to suit different types of medications and dosage forms.
5. Tamper-Evident: Once the foil is punctured or removed, it indicates tampering, thus enhancing safety.
6. Convenience: Blister packaging is easy to handle, distribute, and use, improving patient adherence and medication compliance.
7. Extended Shelf Life: The foil’s barrier properties protect medications from environmental degradation, helping to extend shelf life.
Applications of PTP Aluminum Foil:
Pharmaceutical PTP aluminum foil is widely used for packaging various types of tablets, capsules, granules, and other pharmaceutical products, and it is also used in the packaging of health supplements and some cosmetics.
Prescription and Over-the-Counter Drugs: Used for single-dose packaging of oral solid medications, ensuring safe use.
Traditional Chinese Medicine: Suitable for the sealing of granules and tablets, preventing the volatilization of medicinal effects.
Nutritional Supplements: Such as vitamins, fish oil capsules, etc., to enhance product storage stability.
Medical Device Packaging: Some small medical devices like test strips are also packaged using PTP aluminum foil.
