Alu Alu Foil VS PTP Foil

In the field of pharmaceutical packaging, pharmaceutical aluminum foil plays a vital role. It not only protects drugs from the influence of the external environment, but also extends the shelf life of drugs. Today, let's take a deep look at the alu alu packing and PTP blister foil to understand their differences and their respective scope of application.

Alu alu packaging

It is composed of two layers of aluminum foil with a layer of plastic film in between. This unique structure gives double aluminum packaging many advantages. In terms of barrier properties, it greatly reduces the impact of air on drugs and can effectively prevent drugs from being oxidized.

It reduces the impact of humidity on drugs and prevents them from getting damp and deteriorating; it also reduces the impact of light on drugs, and plays a good protective role for some light-sensitive drugs.

For example, the double aluminum packaging of Niuhuang Jiedu Tablets was launched on the market because it can better protect the quality of drugs, adapt to different sales channels, and enhance the brand image. Double aluminum packaging is suitable for drugs with high requirements for storage environment and poor stability, such as some Chinese medicine preparations or chemical drugs that are easy to oxidize and absorb moisture.

PTP aluminum foil

PTP foil originated in Europe in the 1930s and is an aluminum foil used for pharmaceutical packaging. PTP aluminum foil is a multi-layer structure. From the outside to the inside, it is the outer printing layer, OP primer, aluminum foil layer, and VC adhesive coating. The surface of the aluminum foil is coated with OP protective agent primer, and the other side is coated with VC coating heat seal adhesive.

It is mainly used for blister packaging. It is one of the fastest-growing flexible packaging materials in recent years and is also the main packaging form in the fields of food, health products, and medicines. Its advantage is that it is convenient for consumers to take medicines. When taking medicines, they only need to press lightly to push the tablets out of the blister. However, the surface printing of PTP aluminum foil for blister packaging is relatively simple, single-color printing is common, and anti-counterfeiting measures are relatively few.

What are their differences

In terms of barrier properties, double aluminum packaging is better at blocking air, humidity and light due to its double-layer aluminum foil structure; although PTP aluminum foil also has certain barrier properties, it is relatively weaker.

In terms of ease of use, PTP aluminum foil blister packaging is more convenient for patients to take according to dosage; double aluminum packaging may be relatively troublesome when taking medicine. In terms of cost, double aluminum packaging is usually more expensive than PTP aluminum foil due to material and structure reasons. Haomei Alumium offers different pharmaceutical packaging materials.
