Cold Forming Blister Foil for Medicine Packaging
Blister packaging is a widely used medicine packaging. One of its main raw material is cold forming aluminum foil, of which its thickness and performance are different from the common foil. Learn more.
Cold forming blister packaging, like other pharmaceutical packaging, originated in food packaging applications. In the 1970s, the earliest cold-formed blister prototypes were used to package jams. Then in the mid-1970s, Bayer teamed up with some material scientists to find a suitable packaging for aspirin tablets.
Cold forming blister packaging can protect the performance of the drug very well. Its production speed is very fast and the degree of automation is high. In addition, it also has the characteristics of convenient transportation, light weight and low cost. It is also one of the reasons why it is widely used and is the most important packaging form of capsules and tablets.
Cold forming blister foil is usually used as the covering material. The sheet of the blister pack uses a composite material of pure aluminum as a blister. The application of high-strength alloy aluminum foil in the cold forming packaging makes the cold stamping hard sheet have extremely high resistance to water vapor and oxygen and light insulation, which is unmatched by any other material.
In addition to the function of barrier properties, the intermediate aluminum foil barrier layer used in cold stamping also has functions such as strength support and resistance to stamping and stretching, so it is different from the general aluminum foil for flexible packaging. The cold forming blister foil is an aluminum foil with extremely high strength and good extensibility.
Since the cold stamping hard sheet needs to be stamped, the thickness of the aluminum foil used is much thicker than that of the ordinary composite film. Generally, 45μm thick aluminum foil is used. For the occasions where the stamping is shallow, the aluminum foil thickness can be reduced to 30μm. The maximum thickness can be increased to 70 μm.
