- What is the surface roughness of general aluminum foil?
Shiny side = approx. Ra 0.05 μm,
Matte side = approx. Ra 0.2 μm.
- Is it possible to perform etching on aluminum foil?
Based on the technology we have cultivated through IC cards, our company is capable of etching both aluminum and copper.
- Why does aluminum foil look different on the front and back?
The side in contact with the rolling roll becomes a glossy surface, and the side where the aluminum foil sheets are in contact with each other becomes a matte surface.
- Is it possible to increase the reflectance of aluminum?
By maximizing the smoothness of aluminum foil, highly reflective aluminum foil can also be produced.
- Is aluminum prone to corrosion?
It varies greatly depending on the environment, but moisture requires caution. We also offer highly corrosion-resistant aluminum.
- I am having trouble with metal corrosion caused by gases used in the manufacturing process.
Depending on the gas content, we can also produce aluminum foil with excellent high corrosion resistance using our proprietary technology.
- How can I increase the adhesive strength between aluminum foil and other base materials?
Adhesive strength can be increased by limiting the amount of residual oil to the absolute minimum.
- Are there different types of materials for aluminum foil?
We primarily handle three types, 1N30, 8079, and 8021, as well as other materials, and we are also focusing on the development of new alloys.
- Please tell me the specific gravity of aluminium.
Aluminum is a type of lightweight metal, following metals such as lithium and magnesium, with a specific gravity of 2.7.
- Aluminum foil cracking occurs during the bag-making process for composite materials with a foil configuration; what could be the possible causes?
While it depends on the specification configuration, there is a possibility that the material properties of the aluminum foil are having an effect.
- What are the causes of pinholes?
While there are various possible factors, it often occurs during the final rolling process.
- Do the applications change depending on the material?
Although usage varies depending on the material, it is mostly used for food and pharmaceutical packaging materials, building materials, and electronic components.
- What is your approach to BCP (Business Continuity Plan) measures?
With our three-base system (Osaka, Shizuoka, and Chiba), we can provide peace of mind by being able to handle various risk avoidance measures.
- Which aluminum foil manufacturer has the highest production capacity in Japan?
This is our company, Toyo Aluminium. We produce aluminum foil at three locations: our main manufacturing plant in Osaka, as well as in Shizuoka and Chiba.
