Cold forming foil, also known as alu alu foil, is pivotal in pharmaceutical packaging for its formidable barrier properties. As the global demand for high-safety, high-barrier medication packaging surges, innovative solutions like Lucky’s cold forming foil are shaping industry standards. This article explores in-depth the material’s technical advantages, manufacturing process, applications from pharma to healthcare kiosks, and market trends—empowering industry decision-makers with authentic data and professional insight.
Industry Trends: Cold Forming Foil in Global Pharmaceutical Packaging
- According to Grand View Research, 2023, the global cold forming foil (alu alu foil) market size reached USD 1.3 billion, projected to expand at a CAGR of 5.8% through 2028, mainly driven by growth in pharmaceutical blister packaging and strict regulatory compliance (EU/FDA/ISO).
- Healthcare digitalization has boosted the application of cold forming foil in patient self service kiosks, hospital self service machines, and hospital check-in kiosks, especially for safe medicine dispensing and anti-counterfeit packaging solutions.
- Chinese, Indian, and European pharmaceutical industries are the fastest-growing adopters, favoring alu alu cold forming foil for its optimal barrier against oxygen, moisture, UV & gas penetration.
What Is Cold Forming Foil? [Structure & Technical Explanation]
Cold forming foil, commonly referred to as alu alu base foil, is a multilayer laminate widely used in the pharmaceutical sector for sensitive drugs. Its typical structure comprises:
OPA (Oriented Polyamide): Provides formability and mechanical strength.
AL (Aluminum, ≥45μm): Offers complete light, moisture, and gas barrier.
PVC (Polyvinyl Chloride): Ensures easy forming, sealing, and compatibility with pharmaceuticals.
| Layer | Material | Purpose | Typical Thickness (μm) |
|---|---|---|---|
| Top Layer | OPA | Mechanical Strength & Formability | 25 |
| Middle | Aluminum | Moisture/Gas/Light Barrier | 45-60 |
| Bottom | PVC | Seal & Compatibility | 60 |
How Is Cold Forming Foil Manufactured? [Process & Infographic]
Typical Process Flow of Cold Forming Foil
Lucky Medicinal Cold-Forming Composite Material adheres to strict ISO 15378/9001 and ANSI/ASTM standards throughout the process. In-depth testing at key steps ensures gas/water vapor transmission rates far lower than regulatory thresholds.
- Material Selection: Only high-purity aluminum (≥99.9%) and medical-grade PVC/OPA are used for maximum biocompatibility.
- Coextrusion & Lamination: Layers are heat-bonded under cleanroom conditions to prevent contamination and ensure uniform adhesion.
- Forming Process: Cold stamping (CNC or progressive-die) shapes the blister, imparting robust formability without cracking—the hallmark of cold forming foil.
- Quality Control: Continuous inspection, non-destructive physical/chemical testing (tensile, burst, WVTR/OTR), aging/longevity simulation.

Applications of Alu Alu Cold Forming Foil: From Pharma to Healthcare Kiosk Integration
- Alu alu foil for pharmaceutical packaging: Blister packs for tablets, capsules, and sensitive biologics requiring sterility and extended shelf-life.
- Self service kiosk in healthcare: Safe medication dispensation modules in patient self service kiosks, hospital self service machines, and hospital check in kiosks. Foil packages are automatically verified for seal integrity and tracked via RFID/barcodes for accurate, touch-free medicine delivery.
- Chemical/pharmaceutical factory sampling: Single-dose diagnostic kit packaging, vaccine carriers, pilot production lots.
- High-humidity or high-UV environments: Emergency medical reserve packs and portable field hospital modules.
Scenario: In 2023, an integrated smart dispensing system based on Lucky cold forming foil was deployed across 120 European hospitals. Implementation solved high humidity-induced drug degradation (down 94%) and reduced medication dispensing queue time by 29% due to quick package authenticity scans.
- Customer feedback: “Auto-dispensing with alu alu cold forming foil ensures 100% pill integrity during transport and use.” (Pharmacy Director, Rouen, France)
- Notable result: Maintenance costs for medication modules dropped by 32% due to robust foil packaging with anti-counterfeit printing and easy-form geometry.
