一（yī）次性玉米澱粉餐具有什麽（me）特殊？

一次性玉米澱粉餐具是目前市場上常見的可（kě）降解餐盒。澱粉的主要來源是玉米（mǐ），因此有時也被稱為玉米澱粉基餐具。然而，這種餐盒（hé）實（shí）際上是澱粉和傳統（tǒng）石油基聚丙烯的混合塑料，在其它地方被稱為生物基（jī）。

Disposable corn starch tableware is currently a common biodegradable food box in the market. The main source of starch is corn, so it is sometimes referred to as cornstarch based tableware. However, this type of lunch box is actually a mixture of starch and traditional petroleum based polypropylene plastic, referred to as bio based elsewhere.

玉米澱粉（fěn）餐具是一種可生物降解的餐具，它會導致整個材料的物理性能崩潰。然（rán）而，坍塌（tā）後的石油基PP仍然是不可生物降解的，根據餐盒的成分，降解率可以達到40%-80%，因此隻能視為（wéi）可降解餐盒，而不（bú）是完全降（jiàng）解。

Corn starch tableware is a biodegradable tableware that can cause the physical properties of the entire material to collapse. However, the collapsed petroleum based PP is still non biodegradable, and the degradation rate can reach 40% -80% based on the composition of the lunch box. Therefore, it can only be considered as a biodegradable lunch box, not completely degraded.

負責生物（wù）降解（jiě）的微生物更有可能化學分解材料，這比石油（yóu）基塑料更容易降解。然而，由於添加（jiā）了其他（tā）組（zǔ）分，聚合過（guò）程會增加結晶度。這些因（yīn）素將（jiāng）導致PLA降解時間更長。

Microorganisms responsible for biodegradation are more likely to chemically decompose materials, which is easier to degrade than petroleum based plastics. However, due to the addition of other components, the polymerization process will increase crystallinity. These factors will result in a longer degradation time for PLA.

因此，一次（cì）性玉米澱粉餐具隻（zhī）能在一些程度上取代塑料製品，是目前市場上有爭議（yì）的塑料餐具（jù）替代品。

Therefore, disposable corn starch tableware can only partially replace plastic products and is currently a controversial substitute for plastic tableware in the market.

在超過30℃的高溫（wēn）下，微生（shēng）物開始降解聚乳酸；潮濕時，濕度越（yuè）高，水解（jiě）效率就越高；同時滿足這些條件的環境可以（yǐ）說是自（zì）然界中很罕見（jiàn）的。

At high temperatures exceeding 30 ℃, microorganisms begin to degrade polylactic acid; When humid, the higher the humidity, the higher the hydrolysis efficiency; An environment that simultaneously satisfies these conditions can be said to be rare in nature.

目前，有（yǒu）許多禁止環境塑料的地方，不再（zài）使（shǐ）用降解和完全降解來描述材（cái）料，而是使（shǐ）用它們是（shì）否可以堆肥。因為堆肥可以限製降解時間、降解後（hòu）的顆粒大小以及降（jiàng）解成分對植物生長的影響，以保障材料的。

At present, there are many places where environmental plastics are prohibited, and degradation and complete degradation are no longer used to describe materials, but rather to determine whether they can be composted. Because composting can limit the degradation time, particle size after degradation, and the impact of degradation components on plant growth to ensure the safety of materials.

玉米澱粉餐具品質良好，產品密織性好，耐水、耐油、防滲透，同時具有良好的耐高溫和耐低（dī）溫性（xìng），適合冰箱冷（lěng）凍、冷藏、保鮮食品，微波爐加熱等。

Corn starch tableware has good quality, good product density, water resistance, oil resistance, and penetration resistance, as well as good high and low temperature resistance. It is suitable for refrigerator freezing, refrigeration, preservation of food, microwave heating, etc.

因此，真正保護環境的一次（cì）性玉米澱粉餐具（jù），如（rú）紙漿模塑餐具和植物（wù）纖維模塑餐具（jù）（甘蔗漿餐具），在家庭堆（duī）肥條件下可以完全降解（jiě），目（mù）前在市場上呈現出火熱的發（fā）展趨勢（shì）。

Therefore, disposable corn starch tableware that truly protects the environment, such as pulp molded tableware and plant fiber molded tableware (sugarcane pulp tableware), can be completely degraded under home composting conditions, and is currently showing a hot development trend in the market.
