打包盒使用不当危害性还是不小的
来源:www.sdynbz.com 发布时间:2022-06-17 浏览次数:122
听有新闻讲,一次性外卖打包盒如果被多次使用,会产生对人体有害的物质,引发癌变!其实很多上了年纪的人都有这个习惯,就是因为重复利用打包盒,既可以用来装东西,洗起来也不容易打碎,甚至还可以少洗几次碗,这些无疑是非常方便快捷的。那么打包盒是否真的可以重复使用?是否也能和陶瓷碗一样,利用微波加热呢?
According to the news, if the disposable takeaway box is used for many times, it will produce substances harmful to human body and cause cancer! In fact, many elderly people have this habit. It is because the packaging box can be reused to hold things. It is not easy to break when washing. It can even wash the bowl a few times less. These are undoubtedly very convenient and fast. Can the packing box really be reused? Is it possible to use microwave heating just like ceramic bowls?
我们知道,食品在外包装的配料表上,可以知道它的成分,合不合格,有没有营养。对于打包的餐盒而言,它们也有自己的“身份牌”!有些打包盒确实可以循环使用,以及微波加热,但有些还真得一次性使用。
We know that on the ingredient list of the outer packaging, we can know its composition, whether it is qualified or not, and whether it has nutrition. For packaged lunch boxes, they also have their own "identity cards"! Some packaging boxes can be recycled and microwave heated, but some are really disposable.
在可回收的塑料容器底部,都会有一个三角形形状的标记,里面的数字包含了1-7,总共7个数字(一个三角仅对应一个数字)。这些数字的作用,即是用来区分这些材料的材质以及作用。
At the bottom of the recyclable plastic container, there will be a triangle shaped mark. The number in it contains 1-7, a total of 7 numbers (one triangle only corresponds to one number). The function of these numbers is to distinguish the materials and functions of these materials.
目前已经知道的这7个数字内,有且只有标数字5的塑料打包盒才能真正放入微波炉加热,并且能够做到重复循环使用。而标记为3号、6号、7号的材质,并不推荐加热或循环使用!(1号常见于饮料瓶材料、2号常见于药瓶、4号常见于包装膜)
Among the 7 known figures, only the plastic packaging box marked with number 5 can be put into the microwave oven for heating, and can be reused. The materials marked as No. 3, No. 6 and No. 7 are not recommended to be heated or recycled! (No. 1 is common in beverage bottle material, No. 2 is common in medicine bottle, and No. 4 is common in packaging film)

标记3号:材质为PVC。虽然耐热度可达到80℃,但依然会在高温加热时,产生有害物质,损害身体健康。长期使用,更有致癌风险!故不可加热或重复利用。
Mark No. 3: PVC. Although the heat resistance can reach 80 ℃, it will still produce harmful substances when heated at high temperature, which will damage your health. Long term use, more carcinogenic risk! Therefore, it cannot be heated or reused.
标记6号:材质为PS。高温下,亦会释放危害身体的化学物质,引发癌变。因此,6号数字的餐盒,不可微波加热、不建议重复使用。
Mark No. 6: the material is PS. Under high temperature, it will also release chemicals harmful to the body and cause cancer. Therefore, the No. 6 digital lunch box cannot be heated by microwave and is not recommended to be reused.
标记7号:材质为PC。一般多用于水壶、奶瓶。因为这个材质内会含双酚A,如微波加热,释放的双酚A会导致乳腺癌、前列腺癌等。所以也是不可以加热或重复使用。
Mark No. 7: the material is PC. It is generally used for water bottles and milk bottles. Because this material will contain bisphenol A, such as microwave heating, the release of bisphenol A will lead to breast cancer, prostate cancer, etc. Therefore, it can not be heated or reused.
而标记5号的打包盒,材质采用聚丙烯(PP),透气性高,耐热度强。可耐的高温在120度,低温是在-20度。不管是在加热还是盛热汤、热菜,都不会释放对身体有害的物质。但需要特别注意的是,5号餐盒加热时,需要拿掉盖子,过热的温度,会使其在微波炉内发生爆炸!一次性外卖打包盒如果在盒底没有找到相应标注(即三角形图标、5号数字,和pp字样),代表它无法微波加热,也不可重复使用!
The packing box marked No. 5 is made of polypropylene (PP), which has high air permeability and strong heat resistance. The high temperature is 120 degrees and the low temperature is -20 degrees. No matter it is heating or holding hot soup or hot dishes, it will not release substances harmful to the body. However, it should be noted that when the No. 5 lunch box is heated, the lid needs to be removed. The overheated temperature will cause it to explode in the microwave oven! If there is no corresponding mark (i.e. triangle icon, No. 5 number and PP words) on the bottom of the disposable takeaway packaging box, it means that it cannot be heated by microwave and cannot be reused!
