The quality of PTP aluminum foil packaging is constantly improving, and the application range is also expanding, such as food packaging and health care packaging.
The metal foils used in pharmaceutical packaging applications are aluminum foil, which is called aluminum foil for pharmaceutical packaging (commonly known as PTP aluminum foil), and PTP aluminum foil is from English PressThrough Packaging (literally: packaging by pressure). The more formal term in the industry is for pharmaceutical packaging. Aluminum foil, also known as aluminum foil for blister packaging.
One of the main raw materials for the production of PTP aluminum foil is pharmaceutical grade hard pure aluminum foil, which is customarily called "original aluminum foil" or original foil in the pharmaceutical packaging materials industry. When used as a pharmaceutical packaging material, aluminum foil is the only metal material in the packaging material.
Aluminum foil has:
(1) Non-toxic and odorless;
(2) Excellent electrical conductivity and shading;
(3) Extremely high moisture resistance, gas barrier properties and taste retention, which can protect the packaged objects more effectively. Therefore, it is a packaging material that has not been replaced so far, and neither the vapor-deposited metal film nor the coated special film can completely replace the aluminum foil. In the field of modern packaging and decoration, almost all composite flexible packaging materials that require opacity or high barrier are made of aluminum foil as a barrier layer.
Since the aluminum foil has the above advantages, and has the characteristics of light weight, good strength and good printability, various characters or patterns can be printed thereon. When the blister pack is made, it can be crushed with a little pressure, and the patient takes convenience and is convenient to carry.
