一次性环保餐具：普通的一次性餐盒达不到？

If you pack a bun, a fried food, and endless hot food, will the plastic bag melt under the inherent high temperature? Can toxic and harmful substances occur

一般合格的食品包装袋都是PP聚丙烯材质或PE聚乙烯材质。熔点都在300度左右，一般出锅的食物也有几十度，所以不用担心塑料袋融化。

Generally, qualified food packaging bags are made of PP polypropylene or PE polyethylene material. The melting point is around 300 degrees, and usually the food that comes out of the pot is also several tens of degrees, so there is no need to worry about the plastic bag melting.

PP材料具有耐酸性、耐碱性，能承受150℃的高温。聚乙烯(PE)材料耐油，能承受110℃的高温。塑料在可承受的温度范围内很少发生热解及添加剂迁移，因此也不用担心用塑料袋装早餐生产有害物质。

PP material has acid and alkali resistance, and can withstand high temperatures of 150 ℃. Polyethylene (PE) material is oil resistant and can withstand high temperatures of 110 ℃. Plastic rarely undergoes pyrolysis and additive migration within the acceptable temperature range, so there is no need to worry about using plastic bags to produce harmful substances for breakfast.

注意：建议减少使用塑料袋来长时间装高温食物。外卖打包高温汤品的塑料袋子，不要超过1个小时。

Attention: It is recommended to reduce the use of plastic bags for storing high-temperature food for a long time. The plastic bag for packaging high-temperature soup for takeout should not exceed 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 lives? Here are a few suggestions:

1.、透明度：食品用塑料袋要透明，接触面不能有印刷品。不能用有颜色的塑料袋装食物。

1. Transparency: Plastic bags for food should be transparent, and there should be no printed matter on the contact surface. Food cannot be packed in colored plastic bags.

2、标识：合格食品塑料袋，外面要印有“食品用”等食品专用标识文字或刀叉等图案标识。有SC号码，生产企业。

2. Identification: Qualified food plastic bags should be printed with food specific identification words such as "for food use" or patterns such as knives and forks on the outside. There is an SC number for the production enterprise.

3、厚度：购买食物时不要选择太薄的塑料袋。

3. Thickness: When purchasing food, do not choose plastic bags that are too thin.

4、摸一摸、闻一闻。合格食品塑料袋要透明、无色、无异味、手摸有润滑感。颜色看起来浑浊，有奇怪的味道，手感粘粘的话，很可能是不合格塑料，所以不要使用这种塑料袋。

4. Touch and smell. Qualified food plastic bags should be transparent, colorless, odorless, and have a lubricating feel when touched. If the color looks cloudy, has a strange smell, and feels sticky to the touch, it is likely to be substandard plastic, so do not use this type of plastic bag.

回填土压实后，应分层检查密实度，并做好回填记录。

After the backfilling soil is compacted, the compactness should be checked in layers and backfilling records should be kept.
