The sealing materials (also called lid materials) for pharmaceutical blister packaging in China all use aluminum foil (PTP aluminum foil) with a common thickness of 0.02mm, which requires mold-free, corrosion-resistant, impermeable, solar heat, moisture-proof, light-blocking and high-temperature extinction. The performance of bacteria. Looking at the international PTP packaging market and the development trend of PTP packaging in technologically advanced countries, the production of pharmaceutical blister packaging sealing materials in China should strengthen the development of the following aspects.

1) Hard aluminum foil, soft aluminum foil, composite materials and coated aluminum foil with special requirements can be selected for blister packaging aluminum foil.

2) In addition to the wide application of blister packaging aluminum foil that can be touch-breakable covering aluminum foil, we should also vigorously develop peelable aluminum foil that is easy to uncover and suitable for child-safe packaging and packaging of items that are subject to pressure.

3) Ink printing anti-counterfeiting, laser holographic obscuring anti-counterfeiting and layout anti-counterfeiting can be used, which can be easily identified without increasing the printing cost, making the packaging products impossible or difficult to imitate.

4) The special protective aluminum foil can not only effectively protect the performance of special drugs, but the aluminum wine itself will not be corroded and damaged by related substances in the drugs.

5) Suitable for single-dose medicine and aluminum foil with barcode label. Single-service pharmaceutical packaging will become popular, and the pharmaceutical packaging industry will have to adapt to the future of bar coding.

6) The use of PTP aluminum foil as the bottom sealing material of blister packaging still has unresolved problems. It reduces the recyclability of packaging materials and requires the development of more favorable sealing materials, such as realizing all-plastic packaging sealing.
