When purchasing stainless steel tiffin carrier, consumers should carefully check whether the materials and steel grades used are marked on the outer packaging. At present, there are three kinds of stainless steel used for food contact: Austenitic, martensitic and ferritic stainless steels. The standardized outer packaging shall be marked with the manufacturer's name, address, Executive Standards and other information, as well as the words "for food contact". The materials marked with "18-10", "18-8", "304", "06cr19ni10" and other codes are generally 304 stainless steel. 304 stainless steel has strong corrosion resistance. The use of 304 stainless steel containers wholesale can maximally prevent the breeding of bacteria and ensure the health of users. It is recommended to choose regular supermarkets or stores as far as possible. It is best not to buy the so-called stainless steel lunch boxes in the hands of stall vendors. If such stainless steel lunch box wholesale are not food grade lunch boxes, it may lead to excessive precipitation of heavy metals and affect health.
In addition, we also want to remind consumers that although stainless steel tiffin carrier has many advantages, if we do not pay attention to their correct use methods, it will not only affect their service life but also affect people's health:
First, do not wash with strongly alkaline or oxidizing chemicals such as baking soda, bleaching powder and sodium hypochlorite, because these substances are strong electrolytes and will react electrochemically with steel tiffin box wholesale products.
Second, keep kitchenware clean and scrub frequently, especially after soaking vinegar, soy sauce and other condiments, wash stainless steel food storage containers wholesale products in time and keep dry.
