Pharmaceutical Aluminum Foil in India
Pharmaceutical Aluminum Foil in India is a high-purity aluminum material made specifically for drug packaging. Unlike standard household foil, pharma-grade foil must meet strict quality rules set by international regulators. It protects tablets, capsules, and powders from damage caused by moisture, light, oxygen, and and germs .
Manufacturers in India produce large volumes of this foil for both local use and export. The country has a strong base of raw materials and skilled labor for rolling and coating processes.
Why Indian Pharmaceutical Foil Matters
India is one of the largest suppliers of pharmaceutical packaging materials worldwide. The local industry supports both domestic drug makers and global brands . Indian-made pharma aluminum foil often costs less than European or American alternatives while meeting the same quality standards.
The local climate also helps. Hot weather in many parts of India means drugs need strong barrier packaging to stay stable. Aluminum foil solves this problem directly .
Common Alloy Grades Used in India
Different alloys serve different drug packaging needs.Here are the main grades you will find in the Indian market.
Alloy 8011 aluminum foil
Alloy 8011 is the most common choice for blister lidding foil. It contains iron and silicon as main additions. This gives good strength and formability for cold forming. 8011-H18 temper is the standard for push-through blister packs .
Alloy 8021 aluminum foil
Alloy 8021 has fewer trace elements and higher purity than 8011. It offers better barrier properties and fewer pinholes. This makes it ideal for drugs that are highly sensitive to moisture or oxygen .
Alloy 8079 aluminum foil
Alloy 8079 works well for both pharmaceutical and food blister packaging. It has fine grain structure which helps deep drawing and forming complex shapes .
Alloy 1235 aluminum foil
Alloy 1235 is a commercially pure grade with at least 99.35% aluminum. It is softer and more ductile than 8011. Some strip pack and cold-forming applications use this grade .
Alloy 1050 aluminum foil
Alloy 1050 contains at least 99.5% aluminum. It offers excellent corrosion resistance and is easy to form. It is common for non-cold-formed blister packs .
| Alloy Grade | Main Elements | Strength Level | Best Use |
|---|---|---|---|
| 8011 | Iron, Silicon | Medium | Blister lidding, general pharma |
| 8021 | Higher purity | Medium-high | Moisture-sensitive drugs |
| 8079 | Fine grain structure | Medium | Deep drawing, food-pharma combo |
| 1235 | Pure aluminum | Low | Strip packs, soft forming |
| 1050 | Pure aluminum | Low | Non-cold-formed blister packs |
Temper Designations Explained
The temper tells you how hard the foil is and how it behaves during forming.
H18 Temper
H18 means fully strain-hardened. The foil is stiff and strong. It is the standard temper for cold-formed blister lidding foil .
H19 Temper
H19 is also strain-hardened but slightly harder than H18. Some high-speed lines use this temper for better handling .
Soft Temper
Soft temper means the foil is fully annealed. It is very flexible and easy to form. Strip pack foil often uses this temper .
O Temper
O temper is fully soft and dead annealed. It has maximum formability. This is used when foil must wrap around complex shapes without cracking .
| Temper | Hardness | Formability | Typical Application |
|---|---|---|---|
| O | Very soft | Excellent | Strip packs, deep forming |
| Soft | Soft | Very good | Strip packs, sachets |
| H18 | Hard | Limited | Blister lidding |
| H19 | Very hard | Limited | High-speed blister lines |
Types of Pharmaceutical Aluminum Foil
Indian suppliers offer several types of pharma-grade foil for different packaging formats.
Blister Pack Foil
Blister pack foil is the lidding material sealed onto plastic blister cavities. Patients push through the foil to get the tablet. It usually comes in 20 to 30 micron thickness .
Strip Pack Foil
Strip pack foil wraps individual tablets or capsules between two foil layers. It is thicker than blister foil, often 30 to 50 microns. This format protects drugs from light and moisture .
Cold Form Aluminum Foil
Cold form foil is also called alu-alu foil. It forms the blister cavity itself rather than just the lidding. It offers the highest barrier against water vapor and oxygen. It is used for very sensitive drugs .
Sachet Foil
Sachet foil laminates aluminum with plastic or paper. The aluminum layer is usually 6 to 20 microns thick. used for powders and granules .
Lidding Foil
Lidding foil seals jars, bottles, and containers. It is thicker, often 30 to 50 microns, with heat-seal coating on one side .
Alu-Alu Foil
Alu-alu foil is a multi-layer laminate of aluminum and plastic. used for high-barrier blister packaging. It replaces PVC in cold-forming applications .
| Foil Type | Thickness Range | Structure | Best For |
|---|---|---|---|
| Blister Pack Foil | 20–30 µm | AL/HSL | Tablets, capsules |
| Strip Pack Foil | 30–50 µm | Soft aluminum | Powders, sensitive tablets |
| Cold Form Foil | 120–160 µm | OPA/AL/PVC | High-barrier drugs |
| Sachet Foil | 6–20 µm | AL/PE or AL/Paper | Powders, granules |
| Lidding Foil | 30–50 µm | AL/HSL | Bottles, jars, vials |
| Alu-Alu Foil | 140–180 µm | OPA/AL/PVC | Tropical climate drugs |
Standard Thickness Specifications
Pharmaceutical aluminum foil in India follows common global ranges.Custom sizes are available from most suppliers.
Standard Thickness Ranges
The standard thickness for blister foil is 0.02 mm to 0.04 mm . Strip pack foil is usually 0.03 mm to 0.05 mm. Cold form foil is much thicker at 0.14 mm to 0.18 mm because it forms the cavity itself .
Width Options
Standard roll widths are 200 mm to 1300 mm. Suppliers can slit rolls to smaller widths based on customer needs .
| Thickness Range | Typical Use |
|---|---|
| 0.020–0.025 mm | Light blister packs, low-dose tablets |
| 0.025–0.030 mm | Standard blister lidding |
| 0.030–0.040 mm | Strip packs, heavy tablets |
| 0.140–0.180 mm | Cold form alu-alu cavity |
Surface Coatings and Treatures
Raw foil needs extra layers to work properly in packaging machines.
Heat-Seal Lacquer
Heat-seal lacquer is a coating applied to one side of the foil. It melts under heat to bond foil to plastic films like PVC or PVDC. This is essential for blister sealing .
Primer Coatings
Primer helps ink stick to the foil surface. Printed blister packs need this layer for clear batch numbers and branding .
Protective Coatings
Some foils get extra protective layers to stop reactions between aluminum and active drug ingredients .
OPA Layer
OPA is oriented polyamide film used in cold-form laminates. It protects the outer surface and helps printing .
| Coating Type | Function | Best For |
|---|---|---|
| Heat-seal lacquer | Bonding to plastic | Blister packs, strip packs |
| Primer | Print adhesion | Printed blister packs |
| Protective | Stop drug interaction | Reactive drug formulas |
| OPA | Outer protection | Cold form alu-alu |
Key Quality Tests
Indian suppliers follow international tests to prove foil quality.
Pinhole Test
Pinholes are tiny holes in foil that break barrier protection. Fewer pinholes mean better protection. 8021 alloy has lower pinhole rates than 8011 .
Tensile Strength Test
This measures how hard the foil pulls before it breaks. Blister foil needs 60 to 110 MPA .
Elongation Test
Elongation measures how much foil stretches before breaking. Pharma foil needs at least 1% elongation .
Wetability Test
Wetability grades from A to D. Grade A means the foil surface is clean and ready for coating without extra cleaning .
Barrier Performance
Suppliers test oxygen and water vapor transmission rates. ASTM D3985 checks oxygen barrier. ASTM E96 checks moisture barrier .
| Test Name | Standard | What It Checks |
|---|---|---|
| Pinhole | Visual/automated count | Barrier integrity |
| Tensile strength | ASTM E8 | Breaking strength |
| Elongation | ASTM E8 | Stretch before break |
| Wetability | Grade A–D | Surface cleanliness |
| Oxygen barrier | ASTM D3985 | Oxygen protection |
| Moisture barrier | ASTM E96 | Humidity protection |
