目前市場上的一次性打包盒大多是由石油中提煉的聚苯乙烯原料加上發(fā)泡劑，加熱發(fā)泡而成。聚苯乙烯是一種使用極為廣泛的高分子材料，具有毒性較低、熔點(diǎn)較高、可塑性強(qiáng)、生產(chǎn)簡便等特點(diǎn)，因而成了制一次性快飯盒的選擇材料。一次性打包盒主要有紙類、淀粉類、塑料類及稀有金屬類。現(xiàn)在市面上的發(fā)泡類和碳酸鈣類的飯盒已經(jīng)逐漸被消費(fèi)者及國家政策所不允許使用和用量降低?，F(xiàn)在的飯盒類為環(huán)保飯盒，尤其是玉米淀粉飯盒，其不但環(huán)保而且能解決農(nóng)民的糧食增收和細(xì)加工的規(guī)?；a(chǎn)。

At present, most of the disposable packing boxes on the market are made of polystyrene raw materials extracted from oil and foaming agent. Polystyrene is a widely used polymer material. It has the characteristics of low toxicity, high melting point, strong plasticity and simple production. Therefore, it has become the choice material for making disposable fast lunch boxes. Disposable packing boxes mainly include paper, starch, plastic and rare metals. Now the foamed and calcium carbonate lunch boxes on the market have been gradually prohibited and reduced by consumers and national policies. The current lunch boxes are environmentally friendly lunch boxes, especially corn starch lunch boxes, which are not only environmentally friendly, but also can solve the large-scale production of increasing farmers' grain income and fine processing.

一次性飯盒的類型有以下幾種：淀粉型的一次性飯盒以淀粉為原料的可食用型快飯盒，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。

There are several types of disposable lunch boxes: starch type disposable lunch box edible fast lunch box with starch as raw material. As the name suggests, it is made of starch plants as raw materials, dietary fiber and other edible additives by stirring and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelation and other technologies, with dense layer, internal waterproof layer The utility model is composed of a rubber mesh layer and an outer waterproof layer.

紙板型的一次性飯盒紙板快飯盒是以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。

Paperboard type disposable lunch box paperboard fast lunch box is made of 300-350 grams of bleached kraft wood pulp paperboard through die-cutting bonding, 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 its surface. It is non-toxic and has no side effects on human body in the process of production and use. However, the quality requirements for paperboard are high, and the cost is also increased.
