一次性玉米淀粉餐具有什么特殊？

一次性玉米淀粉餐具是目前市场上常见的可降解餐盒。淀粉的主要来源是玉米，因此有时也被称为玉米淀粉基餐具。然而，这种餐盒实际上是淀粉和传统石油基聚丙烯的混合塑料，在其它地方被称为生物基。

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.

玉米淀粉餐具是一种可生物降解的餐具，它会导致整个材料的物理性能崩溃。然而，坍塌后的石油基PP仍然是不可生物降解的，根据餐盒的成分，降解率可以达到40%-80%，因此只能视为可降解餐盒，而不是完全降解。

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.

负责生物降解的微生物更有可能化学分解材料，这比石油基塑料更容易降解。然而，由于添加了其他组分，聚合过程会增加结晶度。这些因素将导致PLA降解时间更长。

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，一次性玉米淀粉餐具只能在一些程度上取代塑料制品，是目前市场上有争议的塑料餐具替代品。

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

在超过30℃的高温下，微生物开始降解聚乳酸；潮湿时，湿度越高，水解效率就越高；同时满足这些条件的环境可以说是自然界中很罕见的。

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，有许多禁止环境塑料的地方，不再使用降解和完全降解来描述材料，而是使用它们是否可以堆肥。因为堆肥可以限制降解时间、降解后的颗粒大小以及降解成分对植物生长的影响，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.

玉米淀粉餐具品质良好，产品密织性好，耐水、耐油、防渗透，同时具有良好的耐高温和耐低温性，适合冰箱冷冻、冷藏、保鲜食品，微波炉加热等。

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，真正保护环境的一次性玉米淀粉餐具，如纸浆模塑餐具和植物纤维模塑餐具（甘蔗浆餐具），在家庭堆肥条件下可以完全降解，目前在市场上呈现出火热的发展趋势。

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.
