The Cold Forming Process: From Raw Material to Finished Packaging

Step 1: Material Preparation and Coating

Manufacturers start with a multilayer foil substrate comprising aluminum and other polymer films.

Coatings like lacquer or ink are applied for adhesion, Imprimibilidad, and anti-tampering features.

Step 2: Cold Forming Technique

Using a sophisticated stamping machine, the foil is pressed into a mold cavity at room temperature. This process:

• Forms the blister shape
• Ensures a precise fit for the pharmaceutical product
• Preserves material integrity by avoiding high-temperature exposure

Step 3: Filling and Sealing

Once formed:

• The blister cavities are filled with the drug, often in an automated environment.
• The cavities are then sealed with a lidding foil or other sealing materials, creating a hermetic barrier.

Step 4: Final Inspection and Packaging

The finished blister packs undergo rigorous quality checks for:

• Seal integrity
• Dimensions and cavity accuracy
• Absence of defects

Subsequently, they are shipped for distribution, ensuring product safety en route.
