Learn how a blister recycling line separates PVC and aluminum from medical blister packs, the process flow, technologies used, and why blister recycling is becoming a profitable opportunity in the circular economy.

Medical blister packaging is widely used to protect tablets and capsules from moisture, contamination, and damage. Most blister packs are made of thermoformed plastics such as PVC or PET, sealed with aluminum foil. This multi-layer structure ensures product safety but creates a major recycling challenge, as plastic and aluminum are tightly bonded and cannot be separated by conventional methods.The blister recycling line efficiently recovers aluminum and plastic using only physical separation methods.

How a Pharmaceutical Blister Recycling Line Works

1. Shredding and Crushing
After being loaded, blister packs undergo shredding or crushing. This process breaks them into small particles and helps weaken the bond between plastic and aluminum.

2. Grinding and Screening
The crushed material is finely ground and screened to achieve a uniform particle size, which is critical for high-precision separation in later stages.

3. Airflow Separation
Air classification separates materials based on weight differences, with lighter plastic carried away while heavier aluminum particles remain.

4. Electrostatic Separation
This is the core technology of the system, using conductivity differences to separate conductive aluminum from non-conductive plastic, with high-quality systems achieving up to 99% aluminum recovery.

5. Dust Collection System
A negative-pressure dust removal system ensures a clean working environment, prevents secondary pollution, and complies with environmental standards.

For customers interested in machine specifications, layout design, and pricing, tailored technical proposals and process configurations can be provided based on capacity requirements, feedstock composition, and site conditions.
