When purchasing disposable lunch boxes and drinking utensils, customers can also understand the quality assurance of the products by looking at the QS mark, production license number, manufacturer, production address and other information on the packaging box. When buying, try to choose the disposable lunch box tableware with smooth surface, uniform color, no pattern, colorless and transparent, and try not to choose the product that is too soft. Next, let's introduce four types of environmental friendly disposable lunch boxes.

，淀粉類：

First, starch:

不利因素：防霉技術(shù)尚未解決，成本過高，即使技術(shù)過關(guān)了，由于我國是糧食短缺，也很難形成市場。

Adverse factors: the anti mildew technology has not been solved, and the cost is too high. Even if the technology passes, it is difficult to form a market because China is a country with food shortage.

第二，可降解塑料：

Second, degradable plastics:

缺陷：該餐具只在塑料中添加光敏劑和淀粉，添加物部分可降解，塑料部分仍不可降解，因此不屬于真正意義上的綠色環(huán)保產(chǎn)品，不宜推廣。

Defect: the tableware only adds photosensitizer and starch to the plastic. The additive part is degradable, and the plastic part is still non degradable. Therefore, it is not a real green environmental protection product and should not be popularized.

 

第三、紙漿類別：

Third, pulp category:

不足之處：A、一個紙模餐盒重25克，成本0.35元，日產(chǎn)4萬只餐盒所需一噸紙漿，相當(dāng)于砍掉一噸計(jì)重的樹木，每年以300天工作日計(jì)算，砍掉近300立方米樹木，對本是森林貧瘠的我國來說，這無疑是雪上加霜，并由此帶來的水土流失、土地荒漠化等問題更加難以想象。B、加上偏高，消費(fèi)者很難接受。C、不宜與放湯同飲，韌性不足。

Disadvantages: a. a paper mold lunch box weighs 25g and costs 0.35 yuan. A ton of pulp is required for a daily output of 40000 lunch boxes, which is equivalent to cutting down a ton of trees. Based on 300 working days every year, nearly 300 cubic meters of trees are cut down. For China, which is originally a barren forest, this is undoubtedly adding to the snow, resulting in soil erosion Land desertification and other issues are even more unimaginable. B. Coupled with the high price, it is difficult for consumers to accept. C. It is not suitable to drink with soup, and the toughness is insufficient.

第四，植物纖維類：

Fourth, plant fibers:

好處：一是可再生資源來源，二是形成過程中及廢棄后不污染環(huán)境，三是再生產(chǎn)過程節(jié)約資源。以一年生草本植物秸稈纖維為原料制作植物纖維一次性餐具。

Advantages: first, the source of renewable resources; second, it does not pollute the environment during the formation process and after abandonment; third, it saves resources in the reproduction process. The disposable tableware of plant fiber was made with annual herb straw fiber as raw material.
