Pharmaceutical PTP aluminum foil is non-toxic, odorless, light in weight, has excellent shading properties, high moisture resistance and barrier properties. PTP medicinal aluminum foil substrate can be divided into hard aluminum foil and soft aluminum foil. The former is mostly used for the blister packaging of tablets and capsules, and the latter is generally used for the outer packaging of powder granules and powder composite flexible packaging.

The pharmaceutical PTP aluminum foil is generally made of aluminum alloy, which has excellent mechanical properties and pinhole properties, and its roughness and gloss are better than pure aluminum foil, which is beneficial to printing and decoration. The aluminum foil produced by the aluminum used in PTP is non-toxic and tasteless, does not cause any harm to the human body, and has good electrical conductivity and shading performance. Aluminum foil for pharmaceutical packaging also has high gas barrier properties, moisture resistance and taste retention, and no metallized film or coated special film can completely replace aluminum foil. Aluminum foil not only has the above advantages, but also has the characteristics of light weight, certain strength and good printability. With the development of the pharmaceutical industry, the quality requirements for medical aluminum foil are also getting higher and higher.
