The identity is complete
When purchasing plastic tableware, it is first necessary to see if the logo is complete, and then look at the product. The surface of the product should be smooth, free from stains, foreign matter, scratches, cracks, etc., without discoloration or discoloration, and smells of odor such as pungent taste. The most important thing is to look at product identification. This standard stipulates that the product must be marked with the manufacturer's name or trademark, material, and operating temperature. If the product has non-heat-resistant water, it is not suitable for microwave ovens, and oils cannot be contacted. It should be noted that "this standard is clear, and if it is not marked, it is regarded as usable."
The status quo: the identity is not uniform and the quality is uneven
There are many varieties of microwave ovens, but the labels are different, some indicate the use of temperature, use methods, and some only indicate the use of temperature, and some have neither marked the use of temperature nor any instructions. Guangdong is a region and a major distribution center for thermoplastic plastic tableware production enterprises. However, due to the lack of uniform standards, the quality of products on the market is quite different. Some companies use low-quality, low-cost products to seize the market.
Use: only recommend heating below 700W for a short time
Generally speaking, it is relatively safe to use the product logo on the market at a temperature of 140°C. However, even if it is a microwave oven plastic tableware that is qualified according to the standards, it is only recommended to use it under the condition of short-term heating under 700W unless the product is marked as usable. Cooking or other more demanding international certifications can be used under more stringent conditions.
700W is roughly equivalent to the mid-range firepower of microwave ovens. In general, there are instructions for output power corresponding to each firepower in the manual. Short-term heating refers to heating for 2 to 3 minutes and cannot be used for cooking cooked foods. Internationally, appliances used for short-term heating and cooking are not the same. There are two types of plastic tableware in Europe and the United States that can be used for cooking, but it is rare in the domestic market.
