Recently, MC Aluminum successfully completed the production and packaging of a batch of high-quality PTP (Press Through Packaging) aluminum foil, which has been successfully shipped to Japan. This export not only demonstrates the leading technology of Chinese aluminum processing enterprises in the medical packaging material industry but also strengthens the cooperation between China and Japan in the pharmaceutical and medical device packaging sector.
Introduction to PTP Aluminum Foil
PTP aluminum foil is a high-barrier material specifically designed for pharmaceutical packaging. It is widely used in blister packaging for pharmaceutical tablets and capsules, effectively protecting medicines from light, moisture, oxidation, and other external factors, thereby extending their shelf life and ensuring their safety and stability.
MC Aluminum produces PTP aluminum foil using high-quality aluminum alloy materials (8011, 8021), processed through precision rolling, coating treatment, and printing. Our products comply with Japanese Pharmacopoeia (JP), U.S. FDA, and European Pharmacopoeia (EP) standards, meeting the strict requirements of Japanese pharmaceutical companies for packaging materials.
Commonly Used PTP Aluminum Foil Alloys
8011 aluminum alloy: This is one of the most commonly used alloys in PTP aluminum foil, usually in H18 or O state. 8011-H18 aluminum foil has higher hardness and strength, suitable for blister packaging of tablets and capsules; 8011-O aluminum foil is softer and often used for outer packaging of powder particles and composite soft packaging.
8021 aluminum alloy: Mainly used for tropical blister aluminum foil (aluminum-plastic aluminum), its O state characteristics make it have good flexibility and formability, suitable for drug packaging in special environments.

PTP Aluminum Foil Production Process
1.Raw Material Selection
Uses high-purity aluminum alloys (8011/8021/8079) to ensure optimal mechanical properties and chemical stability.
2.Rolling Process
Cold rolling and annealing techniques ensure aluminum foil reaches the required thickness (commonly 0.02mm-0.03mm) with excellent flexibility.
3.Surface Treatment
Degreasing to remove surface oil and improve print adhesion.
Coating treatments (e.g., PVC, heat seal varnish, protective lacquer) enhance process adaptability.
4.Printing & Slitting
High-precision printing technology ensures clear, non-fading graphics.
Precision slitting meets blister packaging equipment requirements.
5.Quality Control & Packaging
Rigorous testing (pinholes, tensile strength, peel strength, barrier performance) to ensure compliance with international standards.
Dust-free packaging ensures contamination-free transportation, meeting Japan’s high regulatory requirements.
