有的时候有人会问到，用打包袋装热食会产生有毒、有害物质吗？一笼包子，一根油条，吃不完的热食都打包，那么，在高温高油的情况下，打包袋会融化吗？会产生有毒、有害物质吗？

Sometimes someone will ask, will hot food packed in bags produce toxic and harmful substances? A cage of steamed buns, a fried dough stick, and hot food that can't be eaten are packed. Will the bags melt under the condition of high temperature and high oil? Will it produce toxic and harmful substances?

实际上，一般合格的食品打包袋都是PP聚丙烯材质或PE聚乙烯材质。他们的熔点都在300度左右，一般出锅的食物也就几十度，所以不必担心打包袋会融化。

In fact, generally qualified food packaging bags are made of PP polypropylene or PE polyethylene. Their melting point is about 300 degrees, and generally the food out of the pot is only dozens of degrees, so there is no need to worry about the melting of the bags.

而PP材质耐酸、耐碱，能承受150℃的高温；PE（聚乙烯）材质耐油，能承受110℃的高温。塑料在耐受的温度范围内，基本不会发生热解及添加剂的迁移，所以也不用担心用打包袋装早餐产生有害物质。

PP material is acid and alkali resistant, and can withstand 150 ℃ high temperature; PE (polyethylene) material is oil resistant and can withstand high temperature of 110 ℃. Within the tolerance temperature range, the plastic will basically not undergo pyrolysis and migration of additives, so there is no need to worry about harmful substances produced by packed breakfast bags.

好的办法就是减少使用打包袋来长时间装高温食物。外卖打包高温汤品的打包袋子，好不要超过1个小时。

A good way is to reduce the use of bags to hold hot food for a long time. Take away package for high-temperature soup, no more than 1 hour.

消费者在日常生活中怎么区分袋子的合格与否呢？这里有几个建议：

How do consumers distinguish whether bags are qualified or not in their daily life? Here are some suggestions:

1、看透明度：食品用打包袋，必须是透明的，并且食品接触面不能有印刷物；不能使用有颜色的打包袋装食品。

1. Look at the transparency: the food packaging bag must be transparent, and there must be no printed matter on the food contact surface; Do not use colored packaged food.

2、看标识：合格的外卖打包袋，外面必须印有“食品级”“食品用”等食品专用标识文字或刀叉等图案标识；SC编号，有生产厂家。

2. Look at the logo: the qualified takeout packaging bag must be printed with "food grade", "food for" and other special food logo words or knife and fork logo on the outside; SC number, with manufacturer.

3、看厚度：购买食物时不要选择太薄的打包袋。

3. Look at the thickness: don't choose too thin bags when buying food.

4、摸一摸、闻一闻：合格的外卖打包袋应该是透明、无色、无异味、手摸很有润滑感，如果看上去颜色浑浊不清、闻起来伴随怪味、摸起来手感黏涩，那很有可能是不合格的打包袋（一般是添加了回收料），这样的打包袋就不要使用。

4. Touch and smell: qualified takeaway bags should be transparent, colorless, odorless, and lubricated by hand. If they look muddy, smell strange, and feel sticky, they are likely to be unqualified bags (usually with recycled materials). Such bags should not be used.
