Environmental tableware is a good invention. For people, environmental protection tableware uses relatively simple materials, not too many chemical components, for people to use more safe and healthy. For the whole global environment, the use of environmental protection tableware has the characteristics of easy recovery and treatment, which will not cause great pollution to the environment. Therefore, environmental protection tableware still needs to be widely promoted. So, what materials are environmental protection tableware made of? Today, Xiaobian will take you to understand the environmental protection tableware materials.

用塑料制成的一次性餐盒主要有PP聚丙烯和PS聚苯乙烯兩種，均牲，無味無嗅，PP較柔軟，一般PP使用溫度是 -6度+120度，所以特別適合盛裝熱飯熱菜，可在微波爐里加熱，甚或可在蒸氣柜里蒸煮，改性的PP其使用溫度可控制在 -18度+110度，這種PP所制成的飯盒除了可加熱100度使用外，更可放入冰箱冷藏使用。

The disposable food boxes made of plastic are mainly PP polypropylene and PS polystyrene. They are non-toxic, tasteless and odorless, and PP is soft. Generally, PP is used at a temperature from - 6 ℃ to + 120 ℃. Therefore, it is especially suitable for holding hot rice and hot dishes. It can be heated in microwave oven or even steamed in a steam cabinet. The use temperature of modified PP can be controlled at & nbsp; nbsp; -From 18 ℃ to + 110 ℃, the lunch box made of PP can be heated to 100 ℃ for use, and can also be refrigerated in the refrigerator.

較硬，且透明，但易撕裂，PS在使用溫度達(dá)75度時開始變軟，所以不適宜盛裝熱飯熱菜，但PS的低溫性能很好，是冰淇淋更好的包裝材料。

PS is hard, transparent and easy to tear. PS begins to soften when the temperature reaches 75 ℃, so it is not suitable for hot rice and hot dishes. However, PS has good low-temperature performance and is the best packaging material for ice cream.

有些飯盒為了降低成本，用PP做盒子，用PS做盒蓋，好處是蓋子透明，且PS較硬，可以用較薄片材制成，降低成本，但這種設(shè)計消費者必須明白兩種材料的差異，切記不要把整盒飯連蓋子一并放入微波爐中加熱。

In order to reduce the cost of some lunch boxes, PP is used as the box and PS is used as the cover. The advantage is that the cover is transparent, and the PS is hard. It can be made of thinner sheet material to reduce the cost. However, consumers must understand the difference between the two materials. Remember not to put the whole box of rice with the cover in the microwave oven.

紙板快餐盒是以300-350克的漂白硫酸鹽木漿紙板為原料，通過類似鈑加工的沖壓成型工藝進行模切黏合或模切壓制、定型等工序制成。為防止其滲油或滲水，要在其表面淋膜或施用化學(xué)助劑。在生產(chǎn)與使用過程中對人體是、無副作用的。但對于紙板的質(zhì)量要求較高，隨之成本也提高。

Paperboard fast food box is made of 300-350g bleached kraft pulp paperboard by die-cutting bonding or die-cutting pressing and shaping process similar to sheet metal processing. In order to prevent its oil or water seepage, it is necessary to film or apply chemical additives on its surface. In the process of production and use, it is non-toxic and has no side effects on human body. But for paperboard quality requirements are higher, with the increase in cost.

以淀粉為原料的可食用型快餐盒，顧名思義，它是以淀粉類植物為原料，加入膳食纖維和其他可食用類助劑經(jīng)攪拌捏合而成，它采用生物復(fù)配、聚糖交聯(lián)、鈣離子螯合等技術(shù)精制而成，有致密層、內(nèi)防水層、膠網(wǎng)層和外防水層四部分構(gòu)成.

The edible fast food box with starch as raw material, as the name implies, is made of starch plant as raw material, adding dietary fiber and other edible additives by mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelating and other technologies. It is composed of four parts: dense layer, inner waterproof layer, rubber mesh layer and outer waterproof layer
