Aluminum foil is a very common metal material that can be used as a packaging material. It is also one of the few alloys that can be used as a packaging raw material. Entre ellos, aluminum foil is most commonly used for food packaging or pharmaceutical packaging. Entre ellos, papel de aluminio 20 micron is a commonly used aluminum foil for pharmaceutical packaging.
20mic aluminum foil refers to aluminum foil with a thickness of 20 micrones (0.002papel de aluminio de mm de espesor). 20 micron aluminum foil is a material that is directly rolled into thin sheets with metal aluminum. It has a soft texture, buena ductilidad, a silvery white luster, and is easy to process and print. Por lo tanto, it can be used as a good packaging material for pharmaceuticals.
20 micron medical aluminum foil is a special aluminum foil, a very thin aluminum foil material used in the pharmaceutical and medical industries. Aluminum foil 20mic is known for its barrier properties, strength and ability to maintain the integrity of packaged products. Además, there are other performance advantages. Light, thin and soft: Due to the thin thickness of 0.002mm aluminum foil, 20 micron aluminum foil has the characteristics of light, thin and soft, easy to process and form. Buena conductividad térmica: Aluminum foil itself has good thermal conductivity, entonces 20 micron aluminum foil also has this feature. Resistencia a la corrosión: Aluminum foil is resistant to corrosion to a variety of chemicals, y 20 micron aluminum foil can maintain its characteristics even in special environments. Aislamiento: In electrical applications, 20 micron aluminum foil exhibits good insulation properties.
Barrier properties are the primary consideration for pharmaceutical packaging materials, and should be able to prevent external factors from interfering with the medicine.
A prueba de humedad: protect the contents from moisture and humidity. Light barrier: prevent exposure to ultraviolet and visible light to protect light-sensitive drugs. Oxygen barrier: limit exposure to oxygen to prevent oxidation of sensitive drugs.
The selection of 20 micron aluminum foil pharma alloy is based on its mechanical properties, barrier capability and formability, which are critical for pharmaceutical packaging applications such as blister packaging.
Common alloys for 20 micron aluminum foil pharma
Aleación 8011 Composición: Alabama (balance), Y (0.5% – 0.9%), fe (0.6% – 1.0%) Features: High strength and good ductility. Excellent barrier properties to moisture, oxígeno y luz. Good formability makes it suitable for blister cover foil. Solicitud: Mainly used for blister packaging, strip packaging and heat seal cover foil.
Aleación 8021 Composición: Aluminio (balance), Hierro (0.7% – 1.3%), Silicio (0.5% – 0.9%) Features: Higher strength and higher elongation compared to 8011. Excellent deep drawability, ideal for cold forming blister foil (aluminum-aluminum). Enhanced barrier protection, especially against gases and moisture. Aplicaciones: For cold-formed (aluminum-aluminum) blister packaging where maximum protection is required for highly sensitive pharmaceutical products.
Aleación 8079: Composición: Aluminio (balance), Hierro (0.7% – 1.3%), Silicio (0.05% – 0.3%) Properties: – Excellent tensile strength and good formability. – Very good barrier properties, including resistance to vapor, gas and contaminants. – Typically preferred when higher ductility is required. – Aplicaciones: Primarily used for high barrier packaging such as strip packs and specialty blister foils.
