Product Overview

Alloy and temper

The 30μm 8011 H18 Pharma Blister Foil is made from an 8011 aluminum alloy that is work-hardened to the H18 temper.

The 8000-series alloys are non-heat-treatable, known for their excellent formability, corrosion resistance, and stability in contact with pharma materials.

The H18 designation indicates a specific level of strain hardening that provides improved strength and rigidity without sacrificing substantial ductility.

This combination makes 8011-H18 particularly suited to the delicate yet precise demands of blister-pack manufacturing, where seals must form cleanly and consistently.

Key implications of the 8011 H18 combination:
– High formability supports consistent foil shaping in blister cavities.
– Enhanced strength relative to softer tempers reduces the risk of tearing during punching, sealing, and handling.
– Superior surface quality supports reliable coating adhesion and printability, which is important for unit-dose labeling and tamper-evident features

Thickness and mechanical behavior

A thickness of 30 μm positions the foil in a sweet spot for blister packaging: thin enough to enable high-speed sealing and lamination with polymer films, yet thick enough to provide robust barrier characteristics and puncture resistance. In practice, 30 μm 8011 H18 foil delivers:
– Adequate puncture resistance to protect contents during handling and transport.
– Sufficient stiffness to maintain cavity integrity in blister tooling without excessive flex that could compromise seals.
– Compatibility with standard heat-sealing processes when laminated to film layers (e.g., PVC, PVdC, PET-based films).

Surface coatings and lamination options

Pharmaceutical blister foils are often paired with polymer films via heat sealing to form a hermetic seal around the dosage unit.

The inner surface of 30 μm 8011 H18 Pharma Blister Foil may be standard aluminum with a protective lacquer or subjected to a polymeric coating (for example PVdC or PCTFE) to enhance sealing performance and moisture barrier.

Lamination structures commonly look like:
– Aluminum foil with PVdC or PCTFE coating, laminated to a polyolefin or PET film.
– Aluminum foil backed by corrosion-inhibiting coatings to improve shelf life for sensitive formulations.
– A multilayer laminate where the foil acts as the gas/moisture barrier, and the polymer film provides mechanical formability and sealant interface.

In each case, the coating and lamination choice is driven by the drug’s stability requirements, the chosen blister architecture (e.g., standard PVC blisters, cold-form or cold-formed aluminum), and the intended sterilization or storage conditions.

Applications in Pharma Packaging

Blister pack architecture and suitability

30μm 8011 H18 Pharma Blister Foil is designed for single-dose or unit-dose packaging, where small tablets, capsules, or soft-dose forms must be protected from light, moisture, and oxygen.

Its properties support:
– Light shielding: Aluminum inherently blocks most UV and visible light, preserving photosensitive drugs.
– Moisture and gas barrier: The aluminum layer provides a strong barrier, which is further enhanced by laminated polymer films against water vapor and oxygen.
– Mechanical integrity during form-fill-seal (FFS) processes: The foil’s ductility and stiffness reduce the risk of tearing or wrinkling under high-speed production.

Sealing and compatibility with polymer films

The heat-seal interface between the foil and the laminated polymer film is crucial. For 30μm 8011 H18 Pharma Blister Foil, typical outcomes include:
– Strong heat seals with a wide sealing window, enabling consistent seals across a production shift.
– Compatibility with standard thermo-seal equipment used in pharmaceutical packaging lines.
– Reduced risk of delamination when used with appropriate adhesive or interlayer materials in the laminate stack.

Seal strength is influenced by several factors, including coating chemistry, film type, sealing temperature, dwell time, and pressurization.

In practice, a well-implemented laminate using 30μm 8011 H18 foil often yields seal strengths in the range suitable for pharmaceuticals, with robust performance over typical shelf-life conditions.

Drug stability considerations

A primary function of blister packaging is to shield the drug from environmental factors that could degrade potency or safety. With 30μm 8011 H18 Pharma Blister Foil:
– Moisture ingress is minimized by the metal barrier and the laminate’s moisture-barrier layer.
– Oxygen exposure is reduced, supporting the stability of oxygen-sensitive formulations.
– Light sensitivity is largely addressed by aluminum’s opaque barrier, which helps prevent photodegradation.
– Compatibility with sterilization methods must be verified; some lamination systems are better suited for processes like gamma irradiation or ethylene oxide depending on the drug’s tolerance to processing conditions.

Tamper-evidence and traceability

Pharma blisters frequently incorporate tamper-evident features. Foil and laminate structures are selected to maintain seal integrity while allowing for tamper-detection indicators (e.g., color-shift or micro-laminates).

The 30μm thickness, coupled with appropriate coatings and lamination, supports reliable tamper evidence without compromising barrier performance or patient safety.

Performance Metrics and Standards

Barrier properties

The primary barrier in blister packaging comes from the combination of the aluminum foil and the laminate.

Aluminum’s inherent barrier to gases and moisture is excellent, and 30 μm provides substantial resistance to diffusion.

When combined with dedicated polymer barrier layers in the laminate, products achieve effective protection against:
– Moisture ingress
– Oxygen transmission
– Light exposure

Notes on performance:
– The actual barrier is a system property: the foil is a key component, but the laminate layers contribute significantly to the final WVTR (water vapor transmission rate) and O2 transmission rate.
– The choice of polymer coating (e.g., PVdC, PCTFE) and any additional barrier between foil and drug product can tune the overall performance to match product stability requirements.

Mechanical properties

For 30μm 8011 H18 Pharma Blister Foil, mechanical performance includes:
– Formability suitable for high-speed FFS equipment.
– Puncture resistance adequate to withstand handling through packaging lines and distribution.
– Dimensional stability under typical processing and storage conditions.

Seal strength and peel strength are critical properties for blister packaging.

The foil must produce a reliable seal with the film while permitting easy opening for the patient at the point of use.

Seal strength is influenced by:
– The sealing surface chemistry and coating on the foil
– The sealing film’s properties
– The dwell time and temperature of the sealing process
– The lamination adhesion between foil and polymer film
