In the application of pharmaceutical packaging materials, aluminum foil is an alloy foil with many advantages. Among pharmaceutical packaging materials, 8011 and 8021 of the 8000 series are common aluminum foil alloys. In addition, 1235 aluminum foil of the 1000 series is also an aluminum foil alloy that can be used for pharmaceutical packaging.

And what are the unique advantages of aluminum foil 1235 in the packaging of pharmaceuticals?

The advantages of 1235 aluminum foil in pharmaceutical packaging are mainly reflected in its excellent physical and chemical properties.

Barrier properties of 1235 foil

The permeability of 1235 aluminum foil to water vapor is extremely low, usually less than 1 g/m²·24h, which means that it can almost completely prevent the penetration of moisture and protect the medicine from moisture. 1235 aluminum foil also has excellent barrier properties for oxygen, and the oxygen permeability is usually less than 2 cm³/m²·24h·atm, which effectively prevents the oxidation of medicines. Light barrier: The light reflectivity of 1235 aluminum foil is 88-92%, which can block ultraviolet and visible light of degradable drugs.

Chemical stability of aluminum foil 1235

Aluminum foil has good resistance to most chemicals such as acids, alkalis, salts, etc., and is not prone to chemical reactions, ensuring the stability and safety of drugs.

Sealing of aluminum foil 1235

Aluminum foil can be compounded with plastic films such as PE and PP to form a sealing layer, and its heat sealing strength can reach more than 10 N/15mm, ensuring the sealing of the package.

High temperature resistance of aluminum foil 1235

1235 aluminum foil can withstand temperatures up to 300°C and is suitable for high-temperature sterilized drug packaging.

Mechanical strength of aluminum foil 1235

The tensile strength of aluminum foil is generally between 60-100 MPa, which ensures the durability of the package during transportation and use.

Aluminum foil 1235 printability

The surface of 1235 aluminum foil can be printed with high quality, and the printing resolution can reach 200 lines/inch, ensuring clear and readable information.

Aluminum foil 1235 environmental protection

Aluminum foil 1235 is 100% recyclable, and the recycled aluminum foil can be reprocessed and used, reducing resource waste and environmental pollution.

1235 anti-tampering and anti-counterfeiting protection

Tamper-proof blister packaging ensures consumer safety, and the holographic and printed security features on the aluminum foil make counterfeiting difficult.

Alu 1235 cost-effective and light weight

Although aluminum is more expensive than plastic, its high durability and light weight (2.7 g/cm³ density) make it cost-effective in the long run. Reduce the overall packaging weight and reduce transportation costs.

Compared with other packaging materials, such as plastic or paper, 1235 aluminum foil has obvious advantages in barrier properties and chemical stability. For example, the water vapor permeability of ordinary plastic films may be between tens and hundreds of g/m²·24h, which is much higher than that of aluminum foil. In addition, plastic materials may deform or release harmful substances at high temperatures, while aluminum foil can remain stable.

1235 aluminum foil occupies an important position in the field of pharmaceutical packaging due to its excellent barrier properties, chemical stability, high temperature resistance, mechanical strength, printability and environmental protection.
