有的時候有人會問到，用打包袋裝熱食會產(chǎn)生有毒、有害物質(zhì)嗎？一籠包子，一根油條，吃不完的熱食都打包，那么，在高溫高油的情況下，打包袋會融化嗎？會產(chǎn)生有毒、有害物質(zhì)嗎？

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?

實(shí)際上，一般合格的食品打包袋都是PP聚丙烯材質(zhì)或PE聚乙烯材質(zhì)。他們的熔點(diǎn)都在300度左右，一般出鍋的食物也就幾十度，所以不必?fù)?dān)心打包袋會融化。

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材質(zhì)耐酸、耐堿，能承受150℃的高溫；PE（聚乙烯）材質(zhì)耐油，能承受110℃的高溫。塑料在耐受的溫度范圍內(nèi)，基本不會發(fā)生熱解及添加劑的遷移，所以也不用擔(dān)心用打包袋裝早餐產(chǎn)生有害物質(zhì)。

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.

好的辦法就是減少使用打包袋來長時間裝高溫食物。外賣打包高溫湯品的打包袋子，好不要超過1個小時。

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.

消費(fèi)者在日常生活中怎么區(qū)分袋子的合格與否呢？這里有幾個建議：

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，必須是透明的，并且食品接觸面不能有印刷物；不能使用有顏色的打包袋裝食品。

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、看標(biāo)識：合格的外賣打包袋，外面必須印有“食品級”“食品用”等食品專用標(biāo)識文字或刀叉等圖案標(biāo)識；SC編號，有生產(chǎn)廠家。

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：購買食物時不要選擇太薄的打包袋。

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

4、摸一摸、聞一聞：合格的外賣打包袋應(yīng)該是透明、無色、無異味、手摸很有潤滑感，如果看上去顏色渾濁不清、聞起來伴隨怪味、摸起來手感黏澀，那很有可能是不合格的打包袋（一般是添加了回收料），這樣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.
