外賣常用一次性外賣打包盒來給飯菜保溫，一次性保溫盒有塑料型、紙板型、淀粉型、紙漿模塑型等七種，需要注意的是有的材質(zhì)可以放進(jìn)微波爐里加熱，有的不能。下面來展開講講吧。

Take out food is usually packaged in disposable take out boxes to keep food warm. There are seven kinds of disposable heat preservation boxes: plastic, cardboard, starch and pulp molding. It should be noted that some materials can be put into the microwave oven for heating, while others cannot. Let's talk about it.

塑料型

Plastic type

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，均無毒牲，無味無嗅，PP較柔軟，一般PP使用溫度是-6度至+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度至+110度，這種PP所制成的飯盒除了可加熱至100度使用外，更可放入冰箱冷藏使用。

Disposable lunch boxes made of plastic mainly include PP polypropylene and PS polystyrene, which are non-toxic, tasteless and odorless. PP is soft. Generally, the use temperature of PP is - 6 ° C to + 120 ° C, so it is particularly suitable for holding hot meals and hot dishes. It can be heated in a microwave oven or even cooked in a steam cabinet. The use temperature of modified PP can be controlled between - 18 ° C and + 110 ° C. In addition to heating to 100 ° C, It can also be put into the refrigerator for refrigeration.

有些飯盒工廠為了降低成本，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(fèi)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, some lunch box factories use PP as the box and PS as the lid. The advantage is that the lid is transparent and the PS is hard. It can be made of thinner sheets to reduce the cost. However, consumers of this design must understand the difference between the two materials and remember not to put the whole lunch box and the lid into the microwave oven for heating.

紙板型

Paperboard type

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(jìn)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毒、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。

The cardboard fast-food box is made of 300-350g bleached kraft wood pulp cardboard as raw material, through die-cutting bonding or die-cutting pressing, shaping and other processes through a stamping process similar to sheet metal processing. In order to prevent oil or water seepage, film or apply chemical additives on the surface. In the process of production and use, it is non-toxic and has no side effects. However, the quality of paperboard is required to be high, and the cost is also increased.

淀粉型

Starch type

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，使用溫度是-10度至+120度，所以特別適合盛裝熱飯熱菜，可在微波爐里加熱，更可放入冰箱冷藏使用。

The edible fast-food box with starch as raw material, as the name implies, is made of starch plants as raw materials, dietary fiber and other edible additives through mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelation and other technologies. The use temperature is - 10 ° C to + 120 ° C, so it is especially suitable for holding hot meals and hot dishes. It can be heated in a microwave oven and can be put into a refrigerator for refrigeration.

紙漿模塑型

Pulp molding

將木紙漿或蘆葦、蔗渣、麥秸、稻草等一年生草本植物纖維紙漿經(jīng)碎漿和凈化，加入適量無毒化學(xué)助劑，成型、干燥、整型、定型、切邊、消毒制成。產(chǎn)品的美觀性并不高，同時也會增加廢水的污染。

Wood pulp or annual herb fiber pulp such as reed, bagasse, wheat straw and rice straw are pulped and purified, and an appropriate amount of non-toxic chemical additives are added to form, dry, shape, shape, cut and disinfect. The beauty of the product is not high, and it will also increase the pollution of waste water.

植物纖維型

Plant fiber type

在環(huán)保優(yōu)勢上，植物纖維餐盒具有明顯的優(yōu)勢，它是以稻草、稻谷殼、甘蔗渣等提取的植物纖維作為原料，加入成型劑、黏合劑、耐水劑等助劑攪拌通過成型機(jī)成型，加以干燥、整形、消毒等后期加工而成。這些農(nóng)業(yè)的下腳料可成為工業(yè)原料，有助于農(nóng)業(yè)資源的綜合利用。

In terms of environmental protection, the plant fiber lunch box has obvious advantages. It is made of the plant fiber extracted from rice straw, rice husk and sugarcane bagasse as raw materials, mixed with molding agent, adhesive, water-resistant agent and other additives, formed by the molding machine, and then dried, shaped and disinfected. These agricultural leftovers can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.

可降解塑料餐盒

Degradable plastic lunch box

此類餐盒的制造原料是可降解塑料，所謂可降解塑料就是在塑料的生產(chǎn)過程中加入一定量的添加劑，如光敏劑、淀粉等原料，這樣，可降解塑料制品在使用完，并廢棄在大自然中暴露三個月后，可由完整的形狀分解成碎片，因而改善了環(huán)境。

The raw material of this kind of lunch box is degradable plastic. The so-called degradable plastic is to add a certain amount of additives, such as photosensitizer, starch and other raw materials in the production process of plastic. In this way, the degradable plastic products can be decomposed into fragments from their complete shape after being used and discarded in the nature for three months, thus improving the environment.

生物全降解餐盒

Biodegradable lunch box

生物全降解餐盒是一種比較先進(jìn)的環(huán)保產(chǎn)品。它以淀粉為主要原料，加入一年生長期植物纖維粉和特殊的添加劑，經(jīng)過化學(xué)和物理方法處理制成生物全降解快餐盒。由于淀粉是一種可生物降解天然高分子，在微生物的作用下分解為葡萄糖，后分解為水和二氧化碳。

Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds one-year growth period plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast-food box. As starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms and then into water and carbon dioxide.

此外，與其共混的材料也是全降解材料，因此可以說它對環(huán)境沒有任何影響。生產(chǎn)原料淀粉的主要來源，可以是玉米、土豆、紅薯、木薯等一年生長期植物。自然，生物全降解生產(chǎn)原料大部分是糧食作物，對環(huán)境無任何污染可完全代替泡沫餐盒。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://qchfb.cn咨詢了解吧。

In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of raw material starch can be corn, potato, sweet potato, cassava and other one-year growing plants. Naturally, most of the biodegradable raw materials are food crops, which have no pollution to the environment and can completely replace the foam lunch box.
