Corn starch based tableware is a common biodegradable food box in the current market. The main source of starch is corn, so it is sometimes called corn starch based. However, this type of food box is actually a mixture of starch and traditional petroleum based PP plastic, which is called bio based abroad.

玉米淀粉基餐具是通過淀粉的生物降解而致使整個(gè)材料物理性能崩潰，但崩潰后的石油基PP還是不可降解的，降解率根據(jù)餐盒成分可達(dá)40%-80%，所以只能算是可降解餐盒，而不能算是全降解。

Corn starch based tableware causes the physical properties of the entire material to collapse through the biodegradation of starch, but the petroleum based PP after collapse is still non degradable. The degradation rate can reach 40% -80% based on the composition of the lunch box, so it can only be considered a degradable lunch box, not a fully degradable one.

因此玉米淀粉基餐具只能在一定程度上替代塑料制品，是目前市場(chǎng)上飽受爭(zhēng)議的塑料餐具的替代品。

Therefore, corn starch based tableware can only partially replace plastic products and is currently a controversial alternative to plastic tableware in the market.

負(fù)責(zé)生物降解的微生物就越容易對(duì)材料進(jìn)行化學(xué)分解），比石油基的塑料要容易降解很多。但是由于添加了其它成分，同時(shí)聚合的過程會(huì)提高結(jié)晶度。這些因素都會(huì)PLA降解的時(shí)間變長(zhǎng)。

The microorganism responsible for biodegradation is more likely to chemical decomposition the material), which is much easier to degrade than petroleum based plastics. However, due to the addition of other components, the polymerization process will increase crystallinity. These factors will lead to longer degradation time of PLA.

高溫，超過30℃時(shí)，微生物才會(huì)開始降解PLA；

At high temperatures exceeding 30 ℃, microorganisms begin to degrade PLA;

潮濕，濕度越高水解效率越高。

Wet, the higher the humidity, the higher the hydrolysis efficiency.

要同時(shí)滿足這幾個(gè)條件的環(huán)境，在自然界中可以說非常。

The environment that satisfies these conditions simultaneously can be said to be very rare in nature.

目前，世界上環(huán)保禁塑的很多先行例如歐洲已經(jīng)不用降解和完全降解來描述材質(zhì)，而是用是否可堆肥來說明。因?yàn)榭啥逊蕦?duì)降解的時(shí)間，降解后的顆粒大小，降解后成分對(duì)植物生長(zhǎng)的影響都能進(jìn)行限定，來保證材質(zhì)的性。

At present, many leading countries in the world that prohibit environmental plastics, such as Europe, no longer use degradation and complete degradation to describe materials, but rather use whether they can be composted. Because composting can limit the degradation time, particle size after degradation, and the impact of degraded components on plant growth to ensure the safety of the material.

因此像紙漿模塑餐具植物纖維模塑餐具（甘蔗漿餐具）這類，能在家庭堆肥條件下就完全降解的真正意義上的環(huán)保餐具，現(xiàn)在市場(chǎng)上呈現(xiàn)出大熱發(fā)展趨

Therefore, truly environmentally friendly tableware, such as pulp molded tableware and plant fiber molded tableware (sugarcane pulp tableware), which can be completely degraded under household composting conditions, is currently showing a hot development trend in the market
