On the shelves of major supermarkets, food iron boxes are our common iron box packaging products, such as biscuit iron boxes, candy iron boxes, etc. As long as you observe carefully, you will find that the inside and outside of the iron box will be coated with an oil film-like coating. Almost every iron box will have it, so do these coatings have any impact on the foods we eat directly? Today, food iron box manufacturers will give a picture of whether the internal coating of food iron box has an impact on food?

The oil layer painted inside the iron box is usually golden. The technical term is to apply food-grade gold oil. It is mainly used to prevent the items in the packaging from corroding the tinplate box, preventing food from being contaminated on the wall, and can better extend the storage time of food. Common ones include biscuit iron boxes, food jars, etc. It is not difficult to find that the iron boxes are all golden.
The surface of the food iron box is coated with an oil layer, which is commonly known as oil treatment in the iron canning industry. The general coating on the outer surface of the iron box is for decorative effect. Applying this layer of substance is not only for beauty, but also for preventing oxidation and rust and protecting the paint surface, just like the same as a film on a mobile phone screen. This coating material is a non-toxic and harmless oil, with stable chemical properties, strong flexibility and high temperature resistance. There will be no chemical changes at high or normal temperatures and will not affect packaged foods.
