As a special commodity, medicines are inseparable from the protection of pharmaceutical packaging throughout the entire chain from leaving the factory to use. Therefore, whether drug packaging is scientific and reasonable is directly related to the safety and efficacy of the drug.
Pharmaceutical packaging has a long history, but it has always been closely related to the advancement of material science. In 1952, the application of aluminum foil blister in the pharmaceutical field opened up a new concept of pharmaceutical packaging. So, what is blister packaging? As a main form of pharmaceutical packaging, blister packaging is generally composed of covering material and blister material. The covering material is usually aluminum foil or composite aluminum foil, which mainly plays a sealing role and serves as a label inside the drug; while the blister material is usually a hard sheet composed of polyurethane, polyethylene, polypropylene hard sheet and related materials, which is the component of the bubble. The material of construction of the housing cavity.
Why choose aluminum foil as pharmaceutical packaging material? This is determined by the physical and chemical properties of aluminum foil. Aluminum foil has light-shielding, moisture-proof and anti-pollution functions, and has certain advantages in the field of pharmaceutical packaging. Regarding the barrier properties of blister packaging, depending on the material and the thickness of the blister, it can be divided into two types: moisture barrier performance and oxygen barrier performance.
Blister packaging of pharmaceuticals is also called "blister packaging", or PTP (Press Through Packaging) for short. Because blister packaging has good mechanical properties, high and low temperature resistance and corrosion resistance, it is suitable for modern automated packaging line operations. Generally, blister packaging is suitable for automated packaging of pharmaceuticals in tablets, capsules, pills, suppositories, powders and other dosage forms.
For aluminum foil blister packaging, the production process: first blister-form the transparent plastic hard sheet, then fill the grooves with different dosage forms of medicines such as tablets, pills, granules or capsules, and then combine them with adhesive-coated Aluminum foil sheets are heated and glued together. In this way, an independent sealed package is formed.
Aluminum foil blister packs are usually single-dose packaging, which can contain a single dose of medicine for a single patient. In order to improve the consumer experience, blister packaging is easy to use hard aluminum foil as the covering material, which makes it convenient for consumers to take out the medicine immediately after tearing off the aluminum foil.
