III. Core Product Advantages (Focus on Pharmaceuticals, Cover Multiple Fields)
1. Pharmaceutical-grade Compliance and Safety to Safeguard Drug Quality
Produced under full-process quality control and risk management, it complies with the 2025 Chinese Pharmacopoeia Guiding Principle 9625 and GMP. Free of harmful impurities, odors and migration when in contact with drugs, it safeguards drug stability, efficacy and patient safety, suitable for solid dosage forms like tablets and capsules.
2. Excellent Barrier Protection to Extend Drug Shelf Life
With excellent barrier properties, it blocks moisture, oxygen, UV rays and pollutants, preventing drug deterioration and extending shelf life. Its multi-layer structure enhances protection and anti-tampering—any tampering leaves obvious traces, ensuring drug integrity during transportation and storage.
3. Excellent Processability to Adapt to Pharmaceutical Production Lines
Highly flexible and easy to form/punch, it fits PTP blister packaging machines perfectly. Formed blister cavities are regular for easy single-dose access. Its flat surface allows clear, non-fading printing of drug information, meeting pharmaceutical labeling standards.
4. High Purity and Quality, Suitable for Multi-scenario Applications
With Al ≥99.35%, it uses high-purity ingots, featuring uniform surface, no scratches/pinholes, and precise tolerance control (thickness ±5%, width ±1mm). Beyond pharmaceuticals, it is widely used in food packaging, electromagnetic shielding, capacitors and more, reducing procurement costs.
5. Green, Environmentally Friendly and Recyclable, in Line with Low-Carbon Concepts
Environmentally friendly and non-toxic, it is 100% recyclable with low recycling costs. It aligns with global low-carbon trends, helps enterprises meet environmental compliance and enhances brand image.
IV. Main Application Fields (Focus on Pharmaceuticals, Cover Full Scenarios)
★ Pharmaceutical Field (Core Application)
Core application: PTP blister packaging for solid drugs (tablets, capsules, granules), including inner lining and sealing foil. It is also used for aluminum-plastic composite packaging and bottle cap sealing, widely recognized in the pharmaceutical industry for compliance and protection.
