How does the PVC/EVOH/PE film package the oral medicine?

Packaging Process (for Blister Packs)

Step-by-Step:
1. Film Feeding:
The PVC/EVOH/PE film is fed into a blister packaging machine (e.g., rotary or linear blister packer).

2. Forming (Embossing):
The film is heated and formed into individual cavities (blister pockets) using a mold. The shape matches the size and contour of the tablets or capsules.

3. Filling:
Medicines are automatically placed into each cavity using a filling station (via vibration feeders, pick-and-place robots, etc.).

4. Lidding (Sealing):
A second layer (usually aluminum foil or another compatible film) is sealed over the formed cavities. However, in some cases, the same PVC/EVOH/PE film can be used as a lidding film if it has a heat-sealable surface.

> Note:* In many applications, the PVC/EVOH/PE film serves as the base sheet, and the **lidding material is aluminum foil coated with a heat-sealable polymer. But in some advanced systems, the same film may be used for both sides.

5. **Cutting & Trimming:
The sealed blister strip is cut into individual units or packs.

6. Final Inspection & Packaging:

Each unit is inspected for defects (e.g., missing tablets, poor seals). Then, they are packed into cartons or secondary packaging.
