PTP medicinal aluminum foil is mainly because aluminum foil is non-toxic, odorless, light in weight, has excellent light-shielding property, has high moisture resistance and barrier property, and is one of the main forms of pharmaceutical packaging.
PTP aluminum foil materials can be divided into hard aluminum foil and soft aluminum foil. The former is mostly used for pharmaceutical tablets and capsule blister packaging, while the latter is generally used as the outer packaging of powder particles and powder for composite flexible packaging. With the development of the pharmaceutical industry, the quality requirements for pharmaceutical foils are rapidly increasing. If the type of printing color increases, the number of color sets increases, and the surface quality of aluminum foil is higher and higher. With the increase of the speed of coating and coloring equipment, higher requirements are imposed on the mechanical properties of aluminum foil.
PTP medicinal aluminum foil generally adopts aluminum alloy materials of 8011-H18 state, mainly has mechanical performance number, excellent pinhole property, roughness and glossiness superior to pure aluminum foil, which is favorable for printing and decoration.
The aluminum foil produced by HTMM is non-toxic and tasteless, does not cause any harm to the human body, and has good electrical conductivity and shading performance, as well as high gas barrier properties, moisture resistance and taste retention, regardless of any metallized film. The coated special film cannot completely replace the aluminum foil. The aluminum foil not only has the above advantages, but also has a light weight, a certain strength, and good printability. The use of aluminum foil to make medicine blister packaging, patients take medicine, carrying is very convenient, so pharmaceutical companies will choose aluminum foil as a pharmaceutical packaging.
