Application of Teflon (PTFE) Coating in Food Industry

Teflon coatings have important applications in the food industry. Since Teflon coatings have excellent non-stick and corrosion resistance properties, they can be used to coat food processing equipment. For example, Teflon coatings can be applied to the interior walls of ovens, baking pans and grills to make food less likely to stick to them, facilitating their trouble-free cleaning and disposal. In addition, Teflon coating can also be used to make food packaging materials, such as heat-sealable films, food bags, etc., to ensure food freshness and hygiene.

In terms of food safety, some people are also worried that PTFE is toxic, so many chefs refuse to use PTFE non-stick pans. However, this is not a problem. DuPont has conducted a lot of experiments and found that it is completely non-toxic at room temperature. It begins to deteriorate when the temperature reaches 260°C and begins to decompose at 350°C. Although it will produce smoke at about 200°C, According to research, the toxicity of this gas is very low, even less toxic than the smoke produced by general cooking oil, and it is impossible to reach such a temperature during the packaging process, so there is no need to worry about the food safety of the PTFE-coated multi-head scale.
