The logo indicates that the complete one is trusted
When buying plastic tableware, first look at the integrity of the logo, and secondly look at the product. The surface of the product should be smooth, free of stains, impurities, scratches, cracks, etc., without discoloration and discoloration, and you can also smell for irritating smells and other odors. The most important thing is to look at the product logo. This standard stipulates that the product must be marked with the manufacturer's name or trademark, material, temperature and other instructions. It should be marked, "This time the standard is clear, and if it is not marked, it is regarded as usable."
Status: Unqualified labels, uneven quality
There are many varieties of tableware for microwave ovens, but the labels are different. Some indicate the use temperature and method of use, some only indicate the use temperature, and some do not indicate the use temperature or any instructions. Guangdong is a relatively concentrated region and main distribution center for thermoplastic tableware manufacturers. However, due to the lack of unified standards, the quality of products on the market varies greatly, and some companies use low-quality and inexpensive products to seize the market.
Use: only recommend short-term heating below 700W
Generally speaking, the product logos on the market are relatively safe to use at temperatures up to 140 ° C. However, even microwave plastic tableware tested according to the standard is only recommended for short-term heating under 700W unless the product is marked as available Only after cooking or other international certifications with higher requirements can be used under stricter conditions.
700W is roughly equivalent to the mid-range firepower of the microwave oven. The general instruction manual has the output power corresponding to each firepower. Short-term heating refers to 2 to 3 minutes of heating, and cannot be used to cook cooked food. In the world, the utensils used for short-time heating and cooking are different. There are two types of plastic tableware in Europe and America that can be used for cooking, but it is rare in the domestic market.
