Hemaokang Steel (Shandong) Co., Ltd. is proud to introduce our premium 0.025mm Thick PTP Aluminum Foil – a specialized packaging material designed for the pharmaceutical and nutraceutical industries. With a high tensile strength and precision custom printing featuring registration marks, this foil ensures reliable sealing and brand consistency on blister machines. As a manufacturer with ISO9001 certification and annual export values exceeding US$50 million, we combine advanced production capabilities with strict quality control to deliver foil that meets the demands of global markets, including North America, Europe, and Southeast Asia.
Our PTP aluminum foil is engineered from high-purity aluminum alloys (8011/8021 series) to achieve consistent thickness at 0.025mm (±5% tolerance) while maintaining excellent tensile strength for smooth unwinding and forming. The foil undergoes a multi-stage annealing process to eliminate pinholes and ensure low water vapor transmission rates, protecting sensitive blister contents like tablets and capsules from moisture and light. We offer custom gravure printing with precise registration marks that enable accurate alignment during high-speed blister packaging, reducing waste and improving production efficiency.
Key Features & Specifications
- Ultra-thin & Consistent Thickness: 0.025mm (25 micron) with strict tolerance control ensures uniform sealing and material savings.
- High Tensile Strength: ≥180 MPa (machine direction) for reliable handling on automatic blister lines without tearing.
- Pinhole-Free Surface: Manufactured in clean-room environments to minimize defects and maintain barrier integrity.
- Custom Printing with Registration Marks: Up to 8-color gravure printing with registration marks (cross or circle) for accurate foil indexing.
- Low Water Vapor Transmission Rate (WVTR): <0.01 g/m²/day at 38°C/90% RH (typical) for long shelf life.
- Excellent Heat-Seal Compatibility: Works with common PVC/PVDC/PE lidding films to form secure blisters.
- Environmentally Friendly: 100% recyclable aluminum, free from organic solvents in printing (upon request).

Application Advantages for Blister Packaging: Our 0.025mm foil is optimized for use on both intermittent and continuous motion blister machines. The high tensile strength reduces breakage during feeding, while the registration marks ensure that printed information (brand logos, dosage instructions, expiration dates) aligns perfectly with each cavity. For pharmaceutical companies, this translates to fewer rejected packs and higher OEE (Overall Equipment Effectiveness). The foil also complies with USP <671> and EP 3.2.5 standards for barrier materials (tested upon request).

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ) for custom printed PTP foil?
A: The MOQ is typically 500 kg per design. For smaller quantities, we might offer stock printed foil with generic registration marks – please inquire with our sales team. -
Q: Can the registration marks be positioned on both edges or just one side?
A: Yes, we can print registration marks on one or both edges of the foil, as well as in the center if required. The position and shape (circle, cross, star) are customizable. -
Q: Is this foil compatible with child-resistant blister packaging?
A: Yes, our PTP foil can be laminated with special heat-seal coatings to meet child-resistant or senior-friendly standards. We recommend testing with your chosen lidding film. -
Q: Do you offer non-printed versions of the 0.025mm foil?
A: Absolutely. We supply plain (non-printed) PTP aluminum foil with the same high tensile strength and thickness, ideal for sterile or generic blister packs. -
Q: How do you ensure the foil is pinhole-free?
A: Our manufacturing process includes multiple rolling and annealing stages, followed by 100% in-line pinhole detection using laser sensors. Any roll with more than 3 pinholes per 100 m² is rejected. -
Q: What are the typical delivery times for orders?
A: For standard width (up to 600mm) and plain foil, delivery is 10–15 working days. Custom printed orders may require 20–25 working days, depending on design complexity. -
Q: Can the foil be supplied with a peelable sealant layer?
A: Yes, we can apply a peelable heat-seal coating on one side to facilitate easy opening. The coating is FDA-compliant for pharmaceutical contact (certificates available upon request). -
Q: What are the storage conditions for this foil?
A: Store in a cool, dry place at
