HC Aluminum Strictly Controls the Quality of 8011 Blister Aluminium Foil

As a professional blister product supplier, HC Aluminum always places product quality as a top priority, strictly implementing full-process quality control in accordance with industry standards to ensure high-quality and highly reliable products for customers. We rigorously monitor and inspect the following key quality indicators:

Appearance Quality Control

The surface must be clean, smooth, free of oil and impurities;

The coating must be uniform and consistent, with no missing areas, bubbling, or peeling;

Printed text and graphics must be correct, clear, firm, and free of misprints, ghosting, or fading;

The surface must not have dense, continuous, or periodic pinhole defects.

Pinhole Density Control

No pinholes with a diameter over 0.3mm are allowed per square meter;

For pinholes with diameters between 0.1–0.3mm, the number must not exceed 1 per m²;

HC Aluminum uses high-resolution CCD pinhole detection systems to ensure each batch meets standards.

Heat Seal Strength

When heat-sealed with PVC, average heat seal strength ≥7.0N/15mm;

When heat-sealed with PVDC, average heat seal strength ≥6.0N/15mm;

Heat seal strength testing ensures stable sealing performance, suitable for high-demand pharmaceutical packaging.

Burst Strength

Product burst strength must not be lower than 98KPa, ensuring structural integrity during packaging and transport.

Adhesion of Protective Layer

The protective layer must bond firmly with the aluminum substrate, with no obvious peeling or delamination, ensuring long-term packaging stability.

Fluorescent Substance Control

The protective and adhesive layers must not contain flaky fluorescent substances, ensuring packaging safety and compliance for contents.

Heavy Metal Limits

Contents of lead (Pb), cadmium (Cd), and arsenic (As) in all products are controlled to ≤0.01%, meeting international environmental regulations (such as RoHS, REACH, etc.).

HC Aluminum ensures every batch of delivered blister aluminum foil products meets customer usage standards and regulatory requirements by continuously optimizing production processes, introducing advanced inspection equipment, and implementing strict quality traceability systems, helping customers achieve safe and stable packaging solutions in high-standard applications such as pharmaceutical packaging.
