Unprinted 20/25 Micron Blister Lidding Foil

In the pharmaceutical industry, the selection of packaging materials is crucial for ensuring drug quality and extending shelf life. Haomei Aluminum, with 15 years of experience in pharmaceutical packaging, has developed unprinted 20/25 micron blister lidding foil to meet the stringent requirements of global pharmaceutical companies for high-barrier, high-cleanliness packaging materials. This product is specifically designed for PTP (Press Through Package) blister packaging and has obtained ISO 15378:2017 international certification for pharmaceutical packaging materials, making it a long-term supplier to multinational pharmaceutical companies such as Dr. Reddy’s in India and EMS Pharma in Brazil.

Technical parameters of Haomei unprinted 20/25 micron blister lidding foil product:

Thickness: 20 microns / 25 microns

Material: High-quality aluminum alloy

Barrier performance: O2 < 0.1 cm³/m²·day, H₂O < 0.1 g/m²·day

Applicable temperature range: -40°C to 120°C

Packaging: Width per roll can be customized to meet customer needs

Why does our unprinted 20/25 micron blister lidding foil product won high reputation on the market of pharmaceutical blister packaging industry?

1. Thickness precision control

20 micron blister lidding foil: Thickness tolerance ±0.5 microns, pinhole density ≤2 pins/m², moisture permeability <0.5g/(m²·24h), barrier performance reaches 3 times that of pharmaceutical-grade aluminized film.

25 micron blister lidding foil: Tensile strength ≥180MPa longitudinally, ≥160MPa transversely, elongation ≥1.5% longitudinally, ≥1.2% transversely, can withstand extreme temperature cycling tests from -40°C to 121°C without cracking.

2. Surface treatment process

Degreasing is performed using an imported German cleaning line, achieving a surface wetting tension ≥38mN/m (water droplet method test), ensuring a heat-sealing strength ≥8N/15mm with substrates such as PVC/PVDC/Aclar. In 2024, 25 micron aluminum blister foil customized for Mylan in the US achieved a zero-leakage rate on a high-speed blister pack machine (300 strokes/minute).

For applied in high end pharmaceutical packaging, our unprinted blister lidding foil has advantages of:

– Excellent barrier properties:

Aluminum foil possesses excellent gas and water vapor barrier properties, effectively preventing the ingress of external moisture and oxygen, ensuring the active ingredients of pharmaceuticals remain unaffected. This characteristic is particularly suitable for drugs sensitive to humidity and oxygen, such as certain biopharmaceuticals and solid dosage forms.

– Compatibility and safety:

Our aluminum foil complies with international pharmaceutical packaging standards, contains no harmful substances, and ensures good compatibility with pharmaceuticals. Rigorous quality testing ensures that every roll of aluminum foil meets high standards, guaranteeing the safety of pharmaceuticals.

Environmental protection:

Haomei Aluminum prioritizes environmental protection; our aluminum foil is recyclable, aligning with the concept of sustainable development. Unprinted aluminum blister foil reduces the environmental impact of chemical inks, meeting the requirements of modern green packaging.

In a project for a large pharmaceutical company, the client needed to package a newly developed antibiotic. This drug was extremely sensitive to humidity and light, and traditional plastic packaging could not meet its requirements. After in-depth communication with the client, we recommended unprinted 25 micron blister lidding aluminum foil, which proved to be a highly successful choice. The drug maintained excellent stability during storage and transportation. The client praised our product and expressed their intention to continue collaborating in future projects.

Unprinted 20/25-micron blister lidding foil is an indispensable choice in the pharmaceutical packaging industry. With its superior performance and environmentally friendly characteristics, it is widely used in the safe packaging of various pharmaceuticals. Haomei Aluminum is committed to providing high-quality aluminum foil products to global customers, contributing to the development of the pharmaceutical industry. We look forward to working with you to create safer and more efficient pharmaceutical packaging solutions.
