1. When buying plastic tableware, first of all, you need to see whether the logo is complete, and secondly, the product.
The surface of the product should be smooth, free of stains, impurities, scratches, cracks, etc., and there should be no discoloration or discoloration. You can also smell it to see if there is any odor such as irritating taste. The most important thing is to look at the product identification. This standard stipulates that the product must be marked with the manufacturer's name or trademark, material, operating temperature and other instructions. It should be marked, "This time the standard is clear, and it is considered usable without it."
2. Status: Inconsistent labeling, uneven quality
There are many types of tableware for microwave ovens, but the labels are different. Some indicate the use temperature and method of use, and some only indicate the use temperature, and some do not indicate the use temperature or any instructions. Guangdong is a relatively concentrated area and main distribution center for thermoplastic tableware manufacturing enterprises. However, because there is no uniform standard, the product quality in the market varies widely, and some enterprises occupy the market with low-quality products.
3. Use: Only recommended for short-time heating below 700W
Generally speaking, the product label on the market is relatively safe to use at 140 ° C. However, even microwave oven plastic tableware that is qualified according to standards, it is only recommended to use under 700W short-term heating unless the product is marked as available It can be used under stricter conditions only after cooking or other international certifications with higher requirements. 700W is roughly equivalent to the mid-range firepower of a microwave oven. General manuals have descriptions of the output power corresponding to each range of firepower. Short-term heating refers to heating for 2 to 3 minutes. It cannot be used for cooking cooked food. Internationally, the utensils used for short-term heating and cooking are different. There are two types of plastic tableware in Europe and the United States that can be used for cooking, but they are rare in the domestic market.
