Advantages of Stainless Steel Fast Food Boxes

Stainless steel fast food boxes, as daily dining containers, have become the preferred choice for many people (especially office workers, students, and outdoor enthusiasts) due to their material characteristics and practical design. The core advantages can be expanded from four dimensions: safety, durability, functionality, and environmental friendliness, as follows: 1、 High safety factor, no harmful substance release This is one of the core advantages of stainless steel fast food boxes, and also the key to distinguishing them from plastic and some inferior ceramic containers: Material stability and high/low temperature resistance: Food grade stainless steel (commonly 304 and 316 models) has extremely stable chemical properties. It does not release plasticizers (such as phthalates) or bisphenol A (BPA) like plastics in the temperature range of -20 ℃ (refrigerated/frozen) to 100 ℃+(microwave heating, boiling water immersion, steaming pot heating), nor does it release heavy metals (lead, cadmium) due to glaze layer detachment like some glazed ceramics. When in direct contact with food such as rice, soup, and oil, it can avoid the risk of "harmful substance migration". No odor residue: The material itself has no odor and is not easy to absorb the taste of food (such as spicy or fishy). After cleaning, there will be no odor residue, and repeated use can keep the container "clean and odorless", avoiding cross contamination and affecting the taste of subsequent food. 2、 Durable and durable, with a long service life The physical properties of stainless steel determine its "durability" attribute, resulting in lower long-term usage costs Anti drop and collision: Compared to glass fast food boxes (which are prone to breakage), ceramic boxes (which are prone to ceramic damage), and plastic boxes (which are prone to deformation and cracking), stainless steel boxes have high hardness and good toughness. When accidentally dropped or squeezed during daily carrying, they are unlikely to be damaged and are suitable for commuting, outdoor and other scenarios. Corrosion resistant and not easy to rust: Food grade stainless steel (especially 316 model, with better corrosion resistance than 304) can resist the erosion of sweat, soup, sauces (such as soy sauce, vinegar and other acidic/alkaline substances). Under normal use and cleaning, it is not easy to rust or oxidize spots, and its service life can reach several years or even longer without frequent replacement.

Why can some stainless steel tableware be placed in the microwave

Whether stainless steel tableware can be placed in a microwave depends on whether its material composition and structural design will conflict with the heating principle of the microwave. To understand this, it is necessary to first clarify the heating logic of the microwave oven, and then analyze the key characteristics of "safe stainless steel tableware". 1、 First understand: Why are microwave ovens afraid of ordinary metals? The heating principle of a microwave oven is to emit 2450MHz microwaves, which penetrate food and excite polar molecules such as water and fat molecules to vibrate at high speed, generating heat through molecular friction (essentially "endogenous heating" rather than external heat conduction). There are two core issues when ordinary metals (including unqualified stainless steel) are placed in a microwave oven: Microwave reflection and sparks: Metal is a good conductor of electricity and strongly reflects microwaves (similar to mirror reflection of light). If the metal surface is uneven (such as patterned or sharp edges), or too close to the inner wall of the microwave oven (metal material), the reflected microwave will form a "high-frequency electric field" locally, breaking through the air and generating sparks, which may ignite food or damage the microwave oven magnetron. Metal heating and scalding: Even without sparks, microwaves can induce "eddy currents" inside the metal, causing rapid heating of the metal itself (especially thin metal sheets). If the temperature of the tableware is too high, it may not only burn hands, but also burn the parts in contact with food. 2、 Stainless steel tableware that can be placed in a microwave oven meets these three key conditions Not all stainless steel cannot enter the microwave oven. Stainless steel tableware that meets the following characteristics can avoid the above risks: 1. Material: Must be "austenitic stainless steel" (mainly 304/316 model) The core components of stainless steel are iron, chromium, and nickel, and the proportion of different components determines its "crystal structure", which directly affects conductivity and microwave reaction: Unsafe stainless steel, such as "martensitic stainless steel" (commonly found in model 430), has a high chromium content and low nickel content. The "free electrons" in the crystal structure are more active, which easily reflects microwaves and generates eddy currents, making it a taboo material for microwave ovens. Safe stainless steel: "Austenitic stainless steel" represented by 304 stainless steel (18% chromium+8% nickel) and 316 stainless steel (18% chromium+10% nickel+2% molybdenum) has higher nickel content, more stable crystal structure, lower reflectivity to microwaves, weak eddy current effect, and will not generate excessive heat or sparks due to microwave excitation. Tip: Regular tableware will be labeled with the material, and when purchasing, it is necessary to confirm the "304 food grade stainless steel" or "microwaveable" label.

Cleaning method for newly purchased stainless steel pot

Cleaning method for newly purchased stainless steel pot: 1. When tearing off the label, soak it in hot water or blow hot air with a fan to easily remove the label completely. 2. Drop a few drops of dishwashing detergent on a damp cloth, and wipe the pot body, lid, and bottom with a damp cloth. 3. Rinse the detergent thoroughly with clean water. 4. Pour white vinegar and water into the pot, heat the pot and let the hot water boil for 5 minutes. 5. Just clean the pot with clean water. Note: Do not use steel wire balls for cleaning.

What are the stainless steels that can be used to make tableware

Although stainless steel has many advantages, not all types of stainless steel can be used to make tableware. Stainless steel is also divided into many different types, each with its own functions. Especially for stainless steel used to make tableware, there are strict requirements and regulations. After being made into tableware, stainless steel will come into direct contact with food. If it does not meet the standards, it is very likely to harm our health. Therefore, China has strict regulations on food and stainless steel that come into direct contact with food. At present, only stainless steel that meets the national mandatory standard GB4806.9-2016 "National Food Safety Standard for Metal Materials and Products in Contact with Food" can be called food grade stainless steel on the market. In this standard, the migration limits of arsenic, cadmium, lead, chromium, and nickel, five heavy metals in stainless steel products, are restricted under specific measurement methods. The 304 stainless steel that we are familiar with, even if it is a food grade stainless steel, can be used to make ordinary prescription loose parts. In addition, there is also 316 stainless steel. 316 stainless steel has a higher nickel content than 304, so its corrosion resistance is better. In addition, other elements are added during the production process. Therefore, this 316 stainless steel is mainly used in the food industry or surgical equipment. When purchasing stainless steel tableware or other kitchen utensils, we must carefully check whether they are labeled as 304 or 316. Do not purchase other types of stainless steel, especially inferior stainless steel, which may contain some heavy metal elements and pose a great threat to our health.

How many models of stainless steel are there

Stainless steel is a commonly used material, and there are many types of this material to meet people's needs. Below, the editor will introduce several models of stainless steel. How many models of stainless steel are there The commonly used models include 301, 304, 306, 309S, 310S, and so on. Stainless steel, also known as stainless acid resistant steel, has a mirror like brightness that makes it feel tough and cold when touched.
