Medicinal aluminum foil and ordinary aluminum foil differ significantly in terms of composition, properties, and applications.

Key Differences

1. Composition and Manufacturing Standards

Medicinal Aluminum Foil:

Made of high-purity aluminum (typically 99% or more).
Manufactured under strict pharmaceutical-grade regulations (p'el ej., FDA or GMP compliance).
Coated or laminated with specialized materials (p'el ej., adhesives, lacquers) to enhance chemical resistance and compatibility with medications.
Ordinary Aluminum Foil:

Contains slightly lower purity aluminum.
May include small amounts of impurities or alloys for cost reduction.
Not subjected to stringent manufacturing standards or coatings.

2. Thickness and Structural Properties

Medicinal Aluminum Foil:

Generally thinner (6-20 Micras) and more precisely controlled.
Excellent flexibility and easy to mold into blister packs.
Ordinary Aluminum Foil:

Typically thicker (10-50 Micras) for household or industrial use.
Structural properties prioritize durability for cooking, insulation, or packaging.

3. Propiedades barrera

Medicinal Aluminum Foil:

Exceptional barrier against light, humedad, oxígeno, and contaminants.
Protects sensitive drugs from degradation and maintains shelf life.
Ordinary Aluminum Foil:

Good barrier properties but less demanding standards.
More prone to pinholes or imperfections that allow minor permeability.

4. Coatings and Laminations

Medicinal Aluminum Foil:

Often coated with materials like heat-seal lacquers or primer layers.
Designed for compatibility with pharmaceutical-grade plastics and inks.
Ordinary Aluminum Foil:

Usually uncoated or minimally treated.
Not suitable for direct contact with sensitive substances.

5. Aplicaciones

Medicinal Aluminum Foil:

Used in blister packs, strip packs, and sachets for tablets, Cápsulas, and powders.
Prevents contamination and maintains sterility.
Ordinary Aluminum Foil:

Widely used for food wrapping, cooking, insulation, and general household or industrial packaging.
Non-sterile applications.
