Publish: Modify: Jan 16, 2024Author: From:  Haomei

The household aluminum foil is also called kitchen aluminum foil and food packaging aluminum foil. 11 micron and 18 micron are two commonly used. How to ensure their quality? Learn more.

The household aluminum foil is also called kitchen aluminum foil and food packaging aluminum foil. Commonly used alloys are 8011 and 1235. The common thicknesses are 8mic, 9mic, 10mic, 11mic, 12mic, 14mic, 15mic, 16mic, 17mic and 18mic. Nowadays, the width of large rolls of household aluminum foil like 11micron aluminium foil can reach 1300mm and are exported abroad. Foreign customers then cut into small rolls by rewinding and slitting.

The testing standards of aluminum foil are mainly evaluated through the following aspects:

1. Thickness detection: The thickness of aluminum foil is a key indicator that determines its strength and durability. According to national standards, the thickness error of aluminum foil should not exceed ±3%. Commonly used measurement methods include stretching method and micro-weighing method.

2. Surface flatness: The surface of the aluminum foil should be flat and smooth, without wrinkles, scratches and other defects. Commonly used inspection methods are visual inspection and the use of touch instruments to detect the flatness of the surface.

3. Tensile strength: The tensile strength of aluminum foil refers to its ability to withstand tensile force. National standards stipulate that the tensile strength of aluminum foil should be in the range of 70-170 MPa. Commonly used measurement methods include tensile testing and tensile strength testing.

4. Elongation at break: Elongation at break refers to the degree of elongation of a material before it is stretched to rupture. National standards require that the elongation at break of aluminum foil should be above 4%. Commonly used measurement methods are tensile test and elongation at break test, etc.

5. Surface coating: Some aluminum foils are coated with special coatings to provide better moisture-proof, oxidation-proof and other properties. The quality of the coating needs to be tested to ensure that it meets standards in terms of uniformity, adhesion and durability.

6. Aluminum foil recycling: Aluminum foil is a recyclable material, and its recycling rate is also an important indicator to evaluate its environmental protection. National standards require that the recycling rate of aluminum foil should reach more than 80%.

7. In addition to the above standards, aluminum foil also needs to meet specific requirements of relevant industries. For example, in the food packaging industry, aluminum foil needs to meet food safety standards and must not contain harmful substances. In the pharmaceutical packaging industry, aluminum foil needs to comply with pharmaceutical hygiene standards to ensure that it does not contaminate pharmaceuticals.
