據了解，快（kuài）餐盒材料化學名稱叫聚乙烯或聚丙（bǐng）烯（xī）。它的（de）強度（dù）較低，不能承受（shòu）80℃以上的高溫（wēn），有一定（dìng）的透（tòu）氣性。我們可以利用感官和（hé）燃燒法來識（shí）別其有性。具體如下：

It is understood that the chemical name of the fast food box material is polyethylene or polypropylene. It has low strength and cannot withstand high temperatures above 80 ℃, with a certain degree of breathability. We can use sensory and combustion methods to identify its non-toxic properties. The details are as follows:
1、的聚乙烯塑料快餐盒為（wéi）乳白色、半透明體，手摸有石蠟滑膩感，質地柔軟能彎曲。放在水中能浮於水麵，沸水中顯（xiǎn）著軟化。遇火容易燃燒，燃燒時滴下蠟狀物，並有燒蠟氣味。火焰為黃色，下端為藍色，煙少（shǎo）。離開火後仍能繼續燃燒。
1. The non-toxic polyethylene plastic fast food box is milky white, semi transparent, and has a smooth paraffin feel when touched. The texture is soft and flexible. It can float on the surface of water and soften significantly in boiling water. It is easy to burn when exposed to fire, and during combustion, wax like substances drop and there is a burning smell. The flame tip is yellow, the lower end is blue, and there is less smoke. Able to continue burning even after leaving the fire.
2、的聚丙烯塑料快餐盒為乳白（bái）色、半透明體（tǐ），手摸潤滑但無滑膩（nì）感，質地硬挺有韌（rèn）性，抖動時聲音清脆。放在水中能浮於水麵，沸水中軟化不顯著。遇火容易燃（rán）燒，燃燒時滴下蠟狀物，膨脹，並有石油氣味。火焰為黃（huáng）色，下端為藍色，少（shǎo）量黑煙。離開（kāi）火後仍能繼續燃燒。
一（yī）次性環保（bǎo）餐具
2. The non-toxic polypropylene plastic fast food box is made of milky white, semi transparent material, which is smooth to the touch but not greasy. The texture is hard and resilient, and the sound is crisp when shaking. It can float on the water surface when placed in water, but softening in boiling water is not significant. It is easy to burn when exposed to fire, and during combustion, wax like substances drip, expand, and have a petroleum odor. The flame tip is yellow, the lower end is blue, and there is a small amount of black smoke. Able to continue burning even after leaving the fire.
3、有（yǒu）毒的聚氯乙烯塑料快餐盒的透明度不（bú）及（jí）聚乙烯，手摸有發黏的感覺，質地柔軟富有（yǒu）彈性，遇（yù）冷變硬，放在水中下沉。不容易燃燒，燃燒時軟化、能拉絲，並有刺鼻的辛辣味。火（huǒ）焰為黃色，下端為綠色，冒黑煙。離開火後慢慢熄滅希望消費者能留神分辨，不（bú）要誤用有毒的塑（sù）料包裝。
3. The transparency of the toxic polyvinyl chloride plastic fast food box is not as good as polyethylene, and it feels sticky when touched. The texture is soft and elastic, and it hardens when cold, and sinks when placed in water. It is not easy to burn, softens when burned, can be brushed, and has a pungent and spicy taste. The flame tip is yellow, the lower end is green, emitting black smoke. After leaving the fire, slowly extinguish it. I hope consumers can be careful to distinguish and not misuse toxic plastic packaging.
