The covering material of cold-formed blister packaging is usually aluminum foil, and the base material for forming the blister is usually a rigid polyvinyl chloride sheet. Due to the limited barrier properties of the latter, it is difficult to ensure the quality of the drug within the period of use. Therefore, now people have developed a cold stamped hard sheet, which uses stamping to replace the original ordinary blister packaging.
The application of high-strength cold forming blister foil in the cold stamping hard sheet 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.
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 thickness of the aluminum foil can be appropriately reduced. Generally, the minimum thickness can be reduced to 30μm.
The blister pack is easy to handle, compact and easy to carry. Due to the use of aluminum foil, each product is individually packaged and protected from all effects until consumed. It is mainly made of 8021-O and 8079-O aluminum foil.
