20mic medical aluminum foil raw materials for pharmaceutical blister packaging alloys

Giấy nhôm để đóng gói

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. Trong số đó, aluminum foil is most commonly used for food packaging or pharmaceutical packaging. Trong số đó, giấy nhôm 20 micron is a commonly used aluminum foil for pharmaceutical packaging.

20lá nhôm y tế mic

20mic aluminum foil refers to aluminum foil with a thickness of 20 micron (0.002lá nhôm dày mm). 20 micron aluminum foil is a material that is directly rolled into thin sheets with metal aluminum. It has a soft texture, độ dẻo tốt, a silvery white luster, and is easy to process and print. Vì thế, it can be used as a good packaging material for pharmaceuticals.

Đặc điểm của 20 micron medical aluminum foil

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.
Ngoài ra, 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.
Độ dẫn nhiệt tốt: Aluminum foil itself has good thermal conductivity, Vì thế 20 micron aluminum foil also has this feature.
Chống ăn mòn: Aluminum foil is resistant to corrosion to a variety of chemicals, Và 20 micron aluminum foil can maintain its characteristics even in special environments.
Vật liệu cách nhiệt: In electrical applications, 20 micron aluminum foil exhibits good insulation properties.

Barrier properties of 20mic foil for pharmaceutical use

Barrier properties are the primary consideration for pharmaceutical packaging materials, and should be able to prevent external factors from interfering with the medicine.

Chống ẩm: 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.

20 micron aluminum foil pharma alloy

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.
