Introduction to 8011 H18 blister aluminum foil
Blister packs are a widely adopted packaging solution for pharmaceuticals, nutraceuticals, consumer healthcare items, and sensitive foods.
The blister foil used in these applications is a specialized aluminum foil that provides barrier performance, formability, and compatibility with sealing layers.
The 8011 H18 variant is among the most popular choices for blister foil due to its combination of ductility, strength, and excellent barrier attributes.
The 8011 alloy belongs to the 8000-series family, which is aluminum with a significant content of manganese and trace alloying elements.
The result is a foil that forms smoothly, resists tearing during high-speed conversion, and maintains barrier integrity when laminated with polymeric sealants and coatings.
The H18 temper denotes a specific level of work hardening—enough to improve strength while preserving adequate malleability for deep-draw forming and reliable curling and sealing during blister process lines.
Key advantages of 8011 H18 blister aluminum foil include:
– Excellent formability for standard blister cavities and unconventional geometries.
– Superior barrier performance against moisture and contaminants when paired with suitable laminates.
– Reliable seal integrity with commonly used pharmaceutical sealants such as heat-sealing coatings and lacquers.
– Consistent thickness tolerances and surface smoothness suitable for high-speed converting equipment.
– Robust compatibility with downstream lamination processes, including cold- and hot-seal laminations, extrusion coatings, and polymeric adhesives.
In practical terms, buyers choose 8011 H18 blister foil when they require a balance of formability, barrier performance, and compatibility with standard lamination chemistries used in pharmaceutical packaging lines.
It is often chosen for tablet and capsule blister packs, sachet packages, and certain food-supplement applications where the foil serves as a protective barrier and a reliable sealing surface.

Key properties and performance characteristics
Material composition and temper
- Alloy: 8011 (Al-Mn based alloy, optimized for formability and barrier properties)
- Temper: H18 (strain-hardened to a defined level; improves strength relative to O or F temps while maintaining good draw properties)
- Typical thickness range for blister foils: 12 to 40 micrometers (0.012–0.040 mm), with common blister foil being in the 20–30 µm range for the aluminum foil layer and a polymer or lacquer sealant layer applied on the exterior.
- Surface finish: Typically bright, highly uniform surface on the foil side that contacts the product; matte or coated options available on the outer coating surface depending on lamination and packaging requirements.
- Core concept: The combination of a thin, strong foil with an appropriate lamination provides effective barriers against moisture, oxygen, aroma, and contaminants, while enabling reliable sealing and easy opening by consumers.
Mechanical and barrier performance
- Tensile strength (typical for 8011 H18 foil in the standard thickness window): 60–120 MPa (varies with exact thickness and processing history)
- Elongation at break: generally low to moderate, reflecting the ductility and work-hardening state of H18; practical values typically in the 2–10% range for the foil alone
- Puncture resistance: adequate for standard blister packaging lines when combined with proper lamination or coatings; performance is influenced by foil thickness, surface finish, and lamination structure
- Water vapor transmission rate (WVTR): highly dependent on laminate structure; aluminum foil itself provides a strong barrier, while WVTR is dominated by the polymer sealant or laminate layer; typical WVTR for a well-designed blister laminate might be in the low to mid single-digit g/m2/24h range in the presence of breathable laminates, but when a robust foil-metal barrier is used with tight lamination, lower WVTR values are achievable
- Oxygen transmission rate (OTR): similarly influenced by laminate; aluminum foil provides near-zero permeability, while the polymeric layers govern OTR in the finished package
Note: In blister packaging, the aluminum foil layer acts as a primary barrier to moisture and gases, while the lamination—often a combination of polymer films and coatings—provides surface properties for sealing and product presentation.
The 8011 H18 blister aluminum foil is chosen for its compatibility with these laminates and its ability to withstand the mechanical demands of high-speed packaging.
Forming and sealing performance
- Deep-draw capability: 8011 alloys in H18 temper offer good formability in standard blister cavities; the thin foil can be formed into the cavities without cracking while maintaining surface integrity
- Sealing compatibility: compatible with common sealants and seal lacquers used in pharmaceutical packaging, enabling reliable heat-seal bonds or cold-seal processes depending on laminate
- Curl resistance: desirable level of curl control arises from foil thickness, temper, and lamination; appropriate tension management in converting equipment reduces curl-related issues on-line
- Compatibility with printing and marking: the foil surface can be finished to permit printing or laser marking on intended areas, enabling batch codes and product information visible through the laminate structure
Coatings and lamination options
- Polymer coatings: heat-seal coatings, sealing lacquers, or functional barrier coatings applied to the foil prior to lamination to improve adhesion, tear resistance, or barrier properties
- Laminates: commonly uses multilayer structures (polyethylene, polypropylene, PET, or polyamide layers) to achieve the desired moisture barrier, chemical resistance, and sealing characteristics
- Barrier enhancements: additional coatings (e.g., fluorinated coatings for chemical resistance) or adhesive layers to improve lamination strength and product compatibility
- Consumer-facing aesthetics: outer laminate can be designed for glossy or matte finishes and include inked or printed branding visible through the laminate
Manufacturing and supply chain considerations
Manufacturing process overview
- Rolling and annealing: the base aluminum foil is produced through a series of rolling steps, with intermediate anneals to achieve the desired thickness and surface properties
- Tempering: post-work hardening steps produce H18 temper, achieving the required strength and formability balance
- Surface treatment: standard mechanical polishing or surface finishing to achieve the target surface quality; optional surface coatings for anti-tingerprint or printability
- Lamination and coating: for blister packaging, the aluminum foil is typically laminated with polymeric films or seal layers; adhesive systems are chosen to maximize bond strength and barrier performance
- Quality control: inline gauges measure thickness consistency; gloss and surface quality checks ensure defect-free foil; transmittance tests, seal strength, and peel tests confirm packaging performance
