Characteristics and application of aluminum foil for PTP
- PTP aluminum foil packaging is used for aluminum-plastic blister packaging of pharmaceutical tablets, capsules, pills, etc. It has a novel appearance and improves the image and competitiveness of pharmaceuticals.
- Excellent sealing strength compared to PVC, PVC/PVDC, PET, PP, PE, and high barrier base materials.
- Made with hard aluminum anodized material, making it easy to break the aluminum foil to access the medicine.
- PTP aluminum foil packaging provides good light-blocking, moisture resistance, gas retention, and flavor retention properties, as well as resistance to oxidation.
- Perfect printing quality with no fading after sealing.
- PTP aluminum foil exhibits exceptional mechanical strength and corrosion resistance, ensuring its suitability for high-speed pharmaceutical packaging production lines, whether at low or high temperatures.
Printing aluminum foil for PTP
- Plain foil (unprinted)
- Printed foil (single-sided printing, double-sided printing, monochrome printing, two-color printing, multicolor printing, colored foil (single-sided gold, two-color gold), double-sided gold, green background, various colored backgrounds)
- Anti-counterfeit (steganography, design, positive and negative printing)
- Single-sided or double-sided printing, providing improved appearance as per requirements.
