What is Food-grade Aluminum Foil?

Here are some of the key specifications of food-grade aluminum foil according to manufacturers:

Purity

Food-grade aluminum foil is typically made of pure aluminum with a high level of purity or 99% and sometimes even higher. The high level of aluminum purity does not contain harmful contaminants that can possibly leach into food making it an exceptional feature of food-grade aluminum foil.

Thickness

There are various ranges of thickness of food-grade aluminum foil from extra-thin to heavy-duty. This allows users to have a choice over suitable specification of food-grade aluminum foil in their type of application. Often, thicker foil is used in cooking, grilling, and food storage while thinner foil is suitable for wrapping and covering food.

Safety Certifications

Surface Treatment

Some food-grade aluminum foil may undergo surface treatments such as anodizing or coating to enhance its resistance to acidic or alkaline foods making sure it can have longer shelf life and prolong service. Furthermore, treatments can also prevent reactions between food and the material to preserve the freshness and taste of the food.

Packaging and Labeling

The packaging of food-grade aluminum foil is usually enclosed in a protective cardboard or plastic box that helps maintain cleanliness during use. It can also be stated and indicated on the labels of packaging that the foil is food-grade material and safe for direct contact with any kind of food.
