Analysis of Blister Packaging: Alu-Alu vs. Alu-Plastic

In modern pharmaceutical packaging, blister packaging (Blister Packaging) is widely used in solid drug packaging such as tablets and capsules due to its superior protection performance and convenient use experience. There are two main common blister packaging forms: Cold Form Foil (Alu-Alu) and PTP Foil. Both have their own advantages in structure, performance and application scenarios. This article will systematically analyze the differences between the two types of packaging for you, and introduce Jiruier's professional product solutions in this field.

1. Characteristics of Aluminum-Aluminum Packaging (Alu-Alu)
Also known as cold-formed aluminum blister packaging, it adopts a three-layer structure of OPA/AL/PVC and is formed by cold forming process. It has the following advantages:

1. **Super strong barrier**: It has excellent oxygen barrier, moisture barrier and light shielding properties, suitable for drugs that are highly sensitive to the environment;

2. **Complete light shielding design**: Suitable for photosensitive drugs;

3. **High mechanical strength**: The blister structure after forming is stable and can effectively prevent damage during transportation;

4. **Suitable for export drugs and high value-added preparations**: It complies with the international mainstream pharmacopoeia standards (such as USP, EP), and is widely used in biological preparations, antibiotics and other fields;

5. **Relatively low molding efficiency and high cost**

2. Characteristics of aluminum-plastic packaging (PTP)
Aluminum-plastic blister packaging is formed by hot pressing PVC (or PVDC) and medicinal PTP aluminum foil, and is currently the most widely used blister packaging form:

1. **High production efficiency**: fast thermoforming speed, suitable for large-scale automated production;

2. **Relatively low cost**: better packaging cost control;

3. **Easy to check the appearance of the drug**: PVC is transparent, and the drug can be seen intuitively, improving user experience;

4. **Moderate barrier performance**: suitable for general drug storage and sales, but not recommended for drugs that are easily affected by moisture and oxygen.
