The blister packaging of tablet capsules purchased by end consumers at pharmacies or hospitals often has various text descriptions, drug names, dosages, or simply the logo of the drug manufacturer printed on the aluminum foil side. These printed products may look identical, but in fact, they generally include two common printing methods. Today we will discuss how to choose the most economical and suitable aluminum foil printing method from the perspective of pharmaceutical factories!

Firstly, let's clarify how these two printing methods are specifically distinguished.

We can start with the structure. Unprinted medicinal aluminum foil mainly consists of three parts: protective agent, aluminum foil, and heat sealing adhesive (from outside to inside). The printing layer can appear on the outermost layer of the protective agent (ink, protective agent, aluminum foil, heat sealing adhesive), or between the protective agent and the aluminum foil (protective agent, ink, aluminum foil, heat sealing adhesive).

It can be divided from procurement channels. If the purchasing channel is a printing factory, then there is a 90% chance that the printed aluminum foil you purchase is printed on the outermost layer. If it is directly purchased by the source manufacturer, it is usually printed on the middle layer.

So another question arises, what are the advantages and disadvantages of these two printing methods? We will also delve into it from several perspectives.

The degree of wear resistance in printing. The aluminum foil printed on the outermost layer has a lower degree of wear resistance. During transportation, if there are bumps or scratches, the printed patterns on the surface will peel off to varying degrees. Therefore, for the durability of printing, the aluminum foil printed between the protective agent and the aluminum foil (protective agent, ink, aluminum foil, heat sealing adhesive) has a better effect.

Printing minimum order quantity. For the packaging of new products, the initial quantity may not be large, and the minimum order quantity for pharmaceutical aluminum manufacturers is usually higher than that for printing factories, generally ranging from 200-500kg. The minimum order quantity for printing factories is around 50-100KG. Therefore, for selling prices that require small batch orders, the quantity of outer printing should be more suitable for the initial procurement of new products.

The cost of printing products. Printing with a low minimum order quantity often has a higher unit price, and the purchasing unit cost of printed materials will also increase.

Therefore, for the procurement of printed pharmaceutical aluminum foil, it is necessary to consider both the finished product and sales volume, and choose the appropriate printing method.
