What are the standards for paint (plastic powder) on the surface of stainless steel water cups? What should be paid attention to in daily use? (I)

Hello everyone, "Dong Dong Talks About Cups" is here. Recently, a reader left a message to the editor, asking why the editor only writes about various types of articles about water cups, and whether it is possible to write articles related to products other than water cups, such as juicers. First of all, the editor would like to thank this friend, which means that you have been following the editor for a while and have read many of the content shared by the editor. http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlSecondly, different trades are like different mountains. The editor is engaged in the cup and pot industry, and the most daily contact is the production of various types of water cups and the corresponding knowledge content, so the editor really cannot share other aspects of the content.

If I just piece together some articles from the Internet and share them with you, I will definitely not do such irresponsible things, and it will also betray everyone's trust in me. Although I have written many articles about water cups, http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlI am indeed in a state of sharing exhaustion, but I will add more industry knowledge in time, and the sharing will become slower and slower later, but I will still persist. Today, I will share with you what are the standards for the paint on the surface of stainless steel water cups? What matters should be paid attention to in daily use?

I won't say too much polite words, let's get straight to the point. Many of the stainless steel water bottles you buy are painted or powder coated, some are glossy, some are matte. Many friends have found that some paint surfaces have poor adhesion, and the paint begins to peel off after a period of use. http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlThis problem may be caused by the production process, or by the paint or plastic powder used on the surface of the stainless steel water bottle not meeting the implementation standards.

1. Must meet food safety standards

Both national industry implementation standards and international standards have clear requirements for the paint used on the surface of water cups. It must be food grade and cannot cause harm to human health. http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlWhen buying water cups, you may wish to ask the product sales whether the paint (plastic powder) used on the surface of the water cup is food grade and meets food safety standards.

According to the editor, the paint used by most water cup manufacturers in the production of water cups does meet food safety standards, http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlbut some unscrupulous manufacturers do not use food-grade paint (plastic powder) in order to gain more market profits. It is difficult for consumers to distinguish the effect after processing.

2. Wear resistance and high temperature resistance of paint (plastic powder)

At the beginning of the article, the editor mentioned that the paint on the surface of the water cup will peel off after a period of use. The main reason here is that the paint's high temperature resistance does not meet the standard. Both are food-grade paints, and there are low-temperature quick-drying paints and high-temperature paints. These two types of paints not only have a huge difference in cost, but also in production management during production. http://www.zhanyict.com/en/ProductsDetail-VB-10330.htmlThe final result is a direct impact on the production cost of the water cup.
