Given that stainless steel silverware is frequently used in homes and restaurants, some forms of metal can safely come in contact with food. Safe food contact materials (FCMs) for packaging are designated by both the European Food Safety Authority (EFSA) and the U.S Food and Drug Administration (FDA). Regulators occasionally revise their opinions on FCMs in light of fresh information.

Types of Safe Metals for Touching Food

The most popular types of metals used for food packaging include aluminum, tin plate, tin-free steel, stainless steel, and metal-based packaging materials in rigid and semi-rigid shapes such cans, foil wraps, and retort pouches. Due to a number of characteristics, including temperature tolerance, light weight, and corrosion resistance, aluminum is a common material of choice for food safety.

Compared to metals, plastics often have a shorter useful life. Due to this limited lifespan, there are accumulations of undesired trash in the workplace, home, or landfills. While some plastics are recycled, the majority remains uncollected in landfills and harms the environment. On the other hand, metal may be recycled repeatedly.
