PTP Aluminum Foil, also known as Pharmaceutical Blister Foil, is a high-quality aluminum foil specifically designed for medicine packaging, ensuring excellent barrier properties, corrosion resistance, and sealability. Produced from 8011 aluminum alloy or 1235 alloy, it meets ASTM B479 and GMP standards, offering safe, odorless, and non-toxic performance for direct or indirect contact with pharmaceutical products.
Our factory produces PTP aluminum foil rolls in various thicknesses (0.025–0.08 mm), widths, and tempers (O, H14, H18). We also provide printed or color-lacquered options for branding and batch information. Advanced cold rolling, annealing, and surface inspection systems ensure uniform thickness, smooth surface, and defect-free foil suitable for high-speed blister packaging machines worldwide.

PTP Aluminum Foil stands for Press-Through-Packaging Aluminum Foil. It's a specialized laminated material primarily used in the pharmaceutical industry to create blister packs for tablets, capsules, pills, and other solid-dose medications.
Here's a breakdown of its key features and structure:
Key Components & Structure (Typical Layers):
Base Layer: Pure aluminum foil (usually 20-25μm thick). Provides excellent:
Barrier Properties: Impermeable to moisture, oxygen, gases, light, and microbes – crucial for drug stability and shelf life.
Strength & Formability: Allows for deep drawing into blister cavities.
Printing Layer (Optional): Allows for branding, dosage information, batch numbers, and expiry dates.
Protective Lacquer/Varnish: Coats the printed side to prevent ink scuffing or reaction with the adhesive.
Heat-Seal Lacquer/Adhesive Layer: Applied to the side facing the blister cavity (usually PVC/PVDC). This layer melts under heat and pressure during the blister sealing process, bonding the foil securely to the plastic blister base.
Superior Barrier Protection: Essential for sensitive medications.
Product Protection: Shields contents from environmental factors.
Tamper Evidence: Any puncture or tear is usually visible.
Dosing Accuracy: Contains individual doses securely.
Ease of Use: Simple "press-through" mechanism for patients.
Compatibility: Works well with common blister base materials like PVC, PVDC, PCTFE, or Aclar.
Printability: Allows clear product identification and regulatory information.
Aluminum Thickness:
Typically 20μm, 25μm (most common), up to 40μm for very demanding barrier needs.
Total Thickness:
Includes all laminated layers (e.g., ~30-50μm total).
Heat Seal Strength:
Critical to ensure the seal integrity during the product's shelf life and easy push-through by the user.
Pinhole Resistance:
High-quality foil is virtually pinhole-free.
