Aluminum foil blister packaging is a widely used way of pharmaceutical product, after a special molding process, drugs are stored in the groove. This kind of molding actually also has a very strict and complex process, each step needs precise design and matching.

Manufacturers will start from the design of packaging format, according to customer requirements of the shape of the product manufacturing Yin mold. A CNC machine was used to mill a series of cavities on the aluminum billet. Install the corresponding die after milling.

The molding process of pharmaceutical aluminum foil bubble cover mostly adopts hot forming or cold forming, and there will be differences according to the different molding methods of bubble cover material. Zum Beispill, medicine pvc and other plastic films are processed by hot forming, an goen folie is processed by cold forming.

For thermoforming machines, the preheating process is performed at a temperature below the melting point of the plastic. Gläichzäiteg, before aluminum blister foil packaging products, products are visually inspected in the staging area to see if there are any major problems. If it is a product, the product is put into the pocket manually or automatically. For some small but bulky products, wéi Pëllen, use a packing machine with a hopper feed. The product is then loaded into the hopper and fed into the pocket of the bubble sheet. Then the product goes into the fixed testing place to check whether the product is unqualified. Here, inspectors or visual sensors check for any damaged or broken items and, if there are damaged products, mark them as rejected at the end of the packing line. After inspection, the plates are transferred to the sealing station.

The final step is to seal the aluminum blister foil package, and before sealing, a cylinder with embossed text or graphics is printed on one side of the lid. The cylinder picks up the ink and presses it onto the capping film to create a surface printing process. Finally transported to the sealing station, the cover film and bubble pack meet by pressing against each other (this is why bubble pack packaging is sometimes called PTP blister pack, by pressure). Finally, heat is applied to form a bond between the two substrates. After bonding, the sealed blister pack is then transferred to the cooling station to secure the bonding.

This sealing is not the last step for aluminum blister foil packers. After fixing the adhesive, the sealed blister sheet needs to be transferred to the dressing station, and the whole larger blister package needs to be cut into blister cards. The blister card then passes through the delivery system, which automatically removes the marked item from the packing line. A conveyor belt guides the blister cards through a robotic arm that automatically collects and places them in boxes or larger packages. After this step, the basic process is almost complete, but there is still one final step left.

Finally, the process operator is required to select samples from the packing line for quality inspection. Through the determination of specific detection methods, generally will focus on the detection of drug sealing degree, barrier performance, etc., will use some special tools.
