PTP packaging is one of the applications of blister packaging. This packaging method is mainly used in the pharmaceutical industry for packaging various tablets, capsules, pills, etc. The main difference between PTP and general blister packaging is that it uses pressurization to fit aluminum foil and plastic blister.
This method uses a blister to hold the tablets and seals them with aluminum medical foil to isolate moisture, preventing the tablets in the package from oxidation and deterioration, or being polluted by the environment. In addition to using transparent plastic shells, PTP packaging can also choose opaque blister shells to further prevent the medicine from deteriorating due to light.
1. It has the properties of oxygen barrier, light-proof and moisture-proof.
2. It is easy to puncture and convenient for taking medicines.
3. It has excellent mechanical properties, heat resistance, low temperature resistance and corrosion resistance, and is suitable for high-speed automated packaging in various environment.
Pharmaceutical PTP aluminum foil generally uses 8011 aluminum foil, which has excellent mechanical properties and few pinholses. Its roughness and glossiness are better than pure aluminum foil, which is conducive to printing and decoration. For example, as the number of printing colors increases, the surface quality requirements of pharmaceutical aluminum foil are getting higher and higher.
8011 aluminum foil for pharmaceutical packaging has high gas barrier, moisture resistance and flavor retention. Not only that, but it also has the characteristics of light weight, certain strength and good printability.
Almost all products in modern packaging that require opaque or high-barrier composite materials use aluminum foil as a barrier layer. This is because aluminum foil has a highly dense metal crystal structure and can block gases, so it is widely used.
It is expected that the medical blister packaging will account for about 60% to 70% of the tablet and capsule packaging of pharmaceuticals in the future, and it is one of the pharmaceutical packaging materials with good development prospects.
At present, the surface printing of PTP aluminum foil for blister packaging is very simple, and single-color printing is more common. There are almost no anti-counterfeiting marks and special anti-counterfeiting materials and means, which provides convenience for counterfeiters to imitate and counterfeit.
Many multinational pharmaceutical groups use PTP aluminum foil products with laser holographic dark pattern anti-counterfeiting. The advantages are that the laser holographic pattern is intuitive and easy for consumers to identify, and it does not affect the original printing design and product packaging appearance, and does not affect the performance of the PTP aluminum foil.
