6 micron aluminum foil refers to aluminum foil with a thickness of 0.006 millimeters. It is an extremely thin aluminum foil product with high technological content. It possesses excellent barrier properties and a wide range of applications. The production of 6 micron aluminum foil requires high-precision rolling equipment and advanced processes. Typically, thick aluminum coils are gradually thinned to a thickness of 6 microns through multiple precision rolling passes.
Core aluminum alloys for 6 micron aluminium foil are primarily 1000 series (1235, 1145), with a smaller amount of 8000 series (8011).
1000 series (pure aluminum foil):
The dominant choice, containing ≥99.35% aluminum, with high elongation, easy to roll into thin specifications, excellent barrier/corrosion resistance, suitable for food/pharmaceutical packaging, and electronic foil.
8000 series (aluminum-iron-silicon alloy foil):
Used in smaller quantities in applications requiring increased strength (such as adhesive tape foil, hookah foil), balancing thin-specification rollability and stiffness.
Properties of 6 micron aluminum foil:
– Lightweight and flexible:
With a thickness of only 6 micrometers, it is extremely thin and lightweight, possessing excellent flexibility, making it easy to fold and roll, and adaptable to various complex packaging and application scenarios.
– Excellent barrier properties:
Aluminum foil itself has good barrier properties, preventing the penetration of light, oxygen, moisture, bacteria, and harmful odors. 6 micron aluminum foil offers even superior barrier properties, significantly extending the shelf life of the packaged product.
– Good thermal conductivity:
Aluminum foil has rapid thermal conductivity, giving it a unique advantage in food packaging and processing. For example, in milk sterilization, aluminum foil packaging can maintain a longer shelf life without refrigeration.
– Superior processing performance:
6 micron aluminum foil is easy to print, color, emboss, and surface coat, meeting the personalized needs of different fields.
– Good electrical conductivity:
It has a certain degree of electrical conductivity, offering potential applications in the electronics field.
Application areas of 6 micron aluminium foil:
– Pharmaceutical packaging:
Due to its excellent barrier and processing properties, 6 micron aluminum foil is widely used in pharmaceutical packaging. It can effectively prevent medicines from getting damp, oxidizing, and deteriorating, ensuring their quality and safety.
– Food packaging:
6 micron aluminum foil also plays a crucial role in food packaging. It can be used to package milk, juice, meat, and other foods, extending their shelf life and maintaining their freshness and taste.
– Antibacterial materials:
6 micron aluminum foil can also be used to prepare antibacterial materials, such as antibacterial packaging films and antibacterial tableware. Its excellent barrier and antibacterial properties effectively prevent bacterial growth and spread.
– Electronics:
It can be used to prepare packaging materials for electronic components such as capacitors and batteries, and can be used as a battery current collector. Although there are certain technical challenges in thinning current collectors, 6 micron aluminum foil has already been tested in some new types of batteries.
– Daily life applications:
It can also be used in hookah foil, adhesive tape foil, and hairdressing foil, meeting the needs of different industries.
– Other applications:
In addition to the pharmaceutical and food packaging fields, 6 micron aluminum foil can also be applied in multiple fields such as chemical engineering and construction. For example, in the chemical industry, it can be used to prepare packaging and storage containers for chemical products.
With increasingly stringent requirements for product quality and safety, the market demand for 6 micron aluminum foil is experiencing rapid growth. This is particularly evident in the pharmaceutical and food packaging sectors, where the need for high-quality aluminum foil is even more urgent. Currently, several companies have the capability to produce 6 micron aluminum foil. China 6 micron aluminum foil not only holds a significant position in the domestic market but is also exported to international markets such as Japan, South Korea, and Southeast Asian countries. This success is attributed to the advantages of China’s aluminum foil industry in technological innovation, product quality, and cost control.
