The plastic box is made of PVC/PET/PP/PS and other transparent folding boxes, cylinders, heaven and earth cover boxes, hand bags, elevators and other related plastic products. Plastic boxes are often used in people's lives. Many people put them in a microwave oven to heat them, but it is not known that high temperature is a catalyst for plastics. Many chemicals in plastics are going to move, so plastic boxes are not suitable for heating in microwave ovens. A place is also unsafe: disinfection cabinets.
Putting a plastic box into the microwave can be fatal
Microwave oven plastic containers cannot be used in microwave ovens. Even plastic containers labeled "Microwave ovens are available" are as small as possible.
Putting plastic boxes in these places is a life
Because high temperatures are the nemesis of plastics, it is possible to make certain substances that are otherwise uneasy.
If you are careful enough, change the plastic container labeled "Microwave Available" to a glass bowl or ceramic dish. The principle of disinfection of disinfection cabinets is mainly strong oxidants or high temperature. Therefore, plastic containers should not be its "regular customers". It is difficult to predict what kind of chemical reaction will occur after a bunch of "active molecules" collide. The easiest way is to clean by hand, although it takes a little effort, but rest assured.
The refrigerator is a "semi-restricted zone" for plastic containers. Low temperature does not promote the dissolution of chemicals, so it is a short time. However, studies have shown that long-term freezing may age the plastic, and after leaving the refrigerator, chemicals can leak as the food melts.
Raw materials may add plasticizer
According to the Hong Kong Consumer Council, 25 plastic lunch boxes labeled as heatable in a microwave oven were tested, and four plasticizer components, DBP, DEHP, DINP and DIDP, were detected from the lids or boxes of the seven samples. The two samples of “LOCK&LOCK†and “JCJ†each detected two plasticizers; the “JCJ†sample lid and box produced in Thailand showed the highest DINP and DIDP content. The reporter noticed that there are many “high-end goods†with a price of around 30 yuan in the list of 7 lunch boxes. At the same time, there are 3 boxes of lunch boxes that will be discolored.
Food safety expert Dong Jinshi told reporters that plastic products are divided into polyvinyl chloride (PVC) plastics, polyethylene (PE) plastics and polypropylene (PP) plastics. PVC plastics contain plasticizers, while PP plastics are generally Plasticizer-free, because the material is transparent enough, no need to add plasticizer. Be aware that the purpose of adding plasticizers to plastics is to make the plastic whiter, more transparent, and more flexible.
