The cookie tin box has better gas barrier properties, moisture resistance, and light-shielding properties than any other material, and it is sealed reliably. The cookie box design can protect the cookies and the printing performance of metal materials. Good, the logo is bright and beautiful, and the packaging container produced is eye-catching. The cookie tin box packaging is an excellent sales packaging, but the tin box is more prone to rust. If stored improperly, it is easy to rust. What should I do? The technicians of the tin box manufacturer below use their own experience to tell everyone how to remove the rust on the tin box and tin can in life.

    First of all, there are some ways to prevent the cookie tin box from rusting, because the general cookie tin box packaging is made of tin-plated iron material, with a tin-plated layer on the outside, which has good airtightness and impermeability. It has the characteristics of light and high temperature resistance, and it is not easy to rust. However, the tin-plated layer on the surface is destroyed during the processing process through galvanizing, blue baking, spray painting and other processing procedures, which causes the raw material iron to leak into the air, and it reacts with the moisture and oxygen in the air to cause the iron box and iron can to rust .

  1. We must know that a humid environment is the easiest way to make the cookie tin box rust. When placing the cookie tin box, we should look for a cool and dry place. Iron is chemically unstable and simply reacts with oxygen in the air or water. When using the cookie tin box, try not to put some sharp objects in it, and don't damage the paint on the outside of the tin can. Do not use excessive force when moving the cookie tin box, and avoid dropping the paint on the outside of the cookie tin box. Finally, a layer of anti-rust or metal maintenance agent can be applied to the surface of the tin box, which can effectively avoid direct contact between iron and air. Therefore, improper storage is easy to rust. Therefore, everyone should pay attention to the following points during the storage process:

1) Try to put the cookie tin box in a dry place and avoid getting wet

2) Do not scratch or damage the paint on the outside of the cookie tin box

3) Do not wipe the cookie tin box with a damp cloth if it is dirty

So what should I do if the cookie tin box is rusty, don’t worry, there is also a way:

      1. Soak the rusty area of ​​the food tin with vinegar for a while, smear it with clear oil, and it will heal in a day;

      2. The uneven tin plating on the surface of the food tin can cause rust, that is, the so-called material is good or bad, so choose a good material to prevent rust;

      3. Do not place food tins in a humid environment, which can reduce the frequency of rusting of food tins;

      4. Soaking in rice water for 50 minutes and then wiping with a dry cloth can remove the rust on the food tins;

      5. Don't damage the paint printing on the appearance of the food tin can. Paint printing that damages the appearance is easy to rust;

      6. The manufacturer should pay special attention to the processes of bone setting, thread winding, and bottom sealing to prevent scratches. The manufacturer should wear gloves when selling food tins. Do not touch the food tins with sweaty hands;

      7. Use tea leaves to soak the rusty parts of the food iron cans. Because the tea contains organic acids such as theanine, which can chemically react with rust, the tea contains organic acids such as theanine that can react with rust to remove The purpose of rust; the main components of tea include water, protein, amino acids, caffeine, polyphenols, carbohydrates, lipids, minerals, plant pigments, vitamins, volatile components, organic acids and inorganic acids. Rust can be soluble as long as it is acid (stearic acid is not soluble in water). The main reason for rust removal is that acid can turn rust into soluble iron salt. The ion equation is H+ +Fe2O3=Fe3+ +H2O; the main component of rust is iron oxide Fe2O3; so the rusty place of the cookie tin box can be removed.

      8. Apply a little toothpaste to the rusty area and wipe gently with a dry cloth or toothbrush.

     Note: Remember not to use a knife or a damp cloth to scrub, otherwise the rust will be more serious.
