What Are Testing Items of Aluminum Foil Food Packaging

Aluminum foil packaging is a material with light weight, low density, high barrier properties, light-shielding properties, UV resistance, good moisture resistance, good anti-corrosion properties, good thermal insulation properties, long shelf life, good ductility, flexibility and high resource recycling. It will surely become the sustainable choice for food packaging.

Aluminum foil food packaging is a material widely used for packaging food. In order to ensure food safety, aluminum foil needs to go through a series of testing items. The following are common testing items for food grade aluminum foil:

1. Dimensional inspection: It includes measurement of thickness, width and length of aluminum foil. These dimensional parameters need to comply with relevant standard requirements to ensure the consistency and quality of aluminum foil.

2. Component analysis: We will analyze the metal components in the aluminum foil to ensure that there are no harmful substances in the product. In particular, heavy metals such as lead and mercury that may be present on aluminum foil require special testing to ensure that they will not migrate into food.

3. Surface treatment: Detection of the surface treatment layer of aluminum foil includes he uniformity, adhesion and wear resistance of the coating. These testing items ensure that aluminum foil can effectively protect food and prevent it from being affected by external factors.

4. Packaging integrity: Test the integrity of the aluminum foil packaging, including whether the seams of the packaging are completely closed and there is no air leakage. These tests ensure that aluminum foil packaging can effectively block the entry of external air and moisture, maintaining the freshness and quality of food.

5. Heat sealing performance: It includes heat sealing strength, sealing and temperature resistance. These testing items ensure that the aluminum foil can maintain appropriate temperature and pressure during the heating and sealing process to ensure food safety and quality.

6. Acidity and alkalinity: It will test the aluminum foil’s acid-base reaction after contact with food. These testing items ensure that the aluminum foil will not react chemically to the food and prevent metal ions in the aluminum foil from dissolving into the food.

These testing items are all designed to ensure the safety and quality of food packaging to protect food from contamination from the external environment and the material itself. These aluminum foil food packaging wholesale undergoes strict testing before being put on the market to provide safe and reliable food packaging materials.
