Custom Printed Aluminum Foil For Pharmaceutical Packaging

Custom printed aluminum foil for pharmaceutical packaging is a packaging material designed specifically for the pharmaceutical industry. It is mainly used to protect drugs from environmental factors such as moisture, light and oxygen, thereby ensuring the effectiveness and safety of drugs. This type of aluminum foil usually has good barrier properties and can effectively extend the shelf life of drugs.

Production process of custom printed aluminum foil

• Substrate selection

– Material: 8011/8021/8079 and other aluminum alloys, usually 20-40μm thick.

– Surface treatment: Corona treatment enhances ink adhesion.

• Printing process

– Gravure printing: high precision, color saturation, suitable for complex patterns.

– Flexographic printing: environmentally friendly water-based ink, suitable for simple graphics.

– Digital printing: small batch customization, flexible and efficient.

• Coating and lamination

– Heat sealing layer (such as PVC, PP) is used to seal with pharmaceutical packaging materials.

– Protective coating improves scratch resistance.

• Slitting and quality inspection

– Slitting to a specified width (such as 20-1000mm), detection of pinholes, thickness uniformity, etc.

Key quality control standards of pharmaceutical packaging foil:

– Printing quality: color difference ΔE≤1.5, clear text without burrs.

– Barrier performance: oxygen permeability ≤0.5 cm³/(m²·24h·0.1MPa), water vapor permeability ≤0.5 g/(m²·24h).

– Heat seal strength: ≥1.5 N/15mm (according to ASTM F88 standard).

– Sanitary certification: SGS test report is required to ensure compliance with the “Chinese Pharmacopoeia” or USP Class VI standard.

Material characteristics and advantages of printed aluminum foil for pharmaceutical packaging:

– High barrier property: prevent oxygen, water vapor, light and microorganisms from invading, and extend the shelf life of drugs.

– High temperature resistance: suitable for high temperature sterilization (such as above 121℃) drug packaging process.

– Printability: supports high-precision graphic printing to meet the needs of brand logo, drug information, anti-counterfeiting code, etc.

– Mechanical properties: with good flexibility, tear resistance and tensile strength, suitable for high-speed packaging production lines.

– Hygiene and safety: Meet pharmaceutical-grade standards (such as FDA, EU, GMP), no risk of toxic migration

Custom printed aluminum foil is widely used in pharmaceutical packaging, including but not limited to:

– Blister packaging: This is the most common form, where each tablet or capsule is individually sealed in a small groove and covered with a layer of custom printed aluminum foil. This packaging method not only protects the medicine, but also facilitates patient use.

– Bar packaging: A certain dose of medicine is packaged in a long strip of packaging, each section can be easily torn open, suitable for one-time use.

– Lid material: Used for sealing bottled medicines, providing additional security, and can be customized to display brand information or medication instructions.

In terms of custom printing, aluminum foil for pharmaceutical packaging can be personalized according to customer needs, such as adding important information such as drug name, dosage instructions, and usage methods, and even adding brand logos and color schemes, which helps to improve brand recognition and patient compliance with medication.

In addition, to ensure safety and compliance, aluminum foil for pharmaceutical packaging needs to comply with relevant regulations and standards, such as the Good Manufacturing Practice (GMP) for pharmaceutical production, the EU Guide to Pharmaceutical Packaging Materials, etc. These regulations ensure the quality and safety of aluminum foil, making it suitable for pharmaceutical products.
