The blister foil used in blister packaging is a sealing material that is tightly sealed on a rigid sheet of medicinal plastic polyvinyl chloride (PVC), so it is also called a cover material. Almost all products in modern packaging that require opaque or high-barrier composite materials use aluminum foil (Mingtai products) as the barrier layer. This is because aluminum foil has a highly dense metal crystal structure that can block gases, so it is widely used.

The main production process of Mingtai Aluminum's blister foil is: billet inspection - billet rolling - split rolling - coil rolling - finished rolling - slitting - furnace annealing - finished product packaging. In the production process, Mingtai Aluminum has very strict control of surface and performance, which mainly reflects the following points:
One: First of all, we must control the quality from the source and strictly inspect the blanks.
Two: During the rolling process, the surface quality of the product is controlled by the control of the clarity and roughness of the roll, the selection of the rolling oil, the reduction of the viscosity of the rolling oil, and the control of the running speed of the machine.
Three: During the product slitting process, ensure that the edges of the aluminum foil rolls are neat and tidy when slitting, and ensure that there are no quality problems such as lotus leaf edges.
Four: In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the medicinal foil to ensure clean degreasing.
