Pharmaceutical PTP aluminum Foil
What Is Pharmaceutical PTP Aluminum Foil
PTP aluminum foil, also known as blister foil or push-through lidding foil is the fastest growing flexible packaging material in recent years, and it is also the main packaging for food, health care products and pharmaceuticals like the blister packing of capsules, tablets, pill, etc.
Structure of Medicine Aluminum Foil
Medicine aluminum foil consists of OP protective layer / AL (aluminum foil layer) / heat seal coating.
PTP aluminum foil can be unprinted or printed. Printed foil can be printed on one side or both sides.
Application of PTP Blister Foil
1. ·Blister pack for chewing gum, mints, etc
2. ·Blister pack for medicines in tablets, capsule, pills, etc
3. ·Blister pack for health care products in tablets, capsule, soft gel, etc.
Features of Medicinal Aluminum Foil
1. It is good shading performance, moisture-proof performance and gas retention performance
2. It also has the function of leak-proof and antipollution and is carryhome.
3. It is capable of being sealed with PVC/ PVDC film or Alu-Alu.

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.
