玉米淀粉餐盒是从玉米中提炼出的淀粉、纤维素等为主要原料,经过高温脱水后,通过压片机压成同等宽度同等厚度的片状材料,经高科技生产工艺加工而成的环保餐盒。优于餐盒本身属生物降解制品,自然条件即可自行降解,避免了对环境的污染,节约了石油等资源,经权威检测部门检测,各项卫生指标均达到标准,高档宾馆、飞机、高铁等领域都在广泛使用。

Corn starch meal box is an environmentally friendly meal box made from starch, cellulose, and other raw materials extracted from corn. After high-temperature dehydration, it is pressed into sheet materials of the same width and thickness using a tablet press, and processed through high-tech production technology. Compared to the food box itself, it is a biodegradable product that can degrade on its own under natural conditions, avoiding environmental pollution and saving non renewable resources such as oil. After being tested by authoritative national testing departments, all hygiene indicators meet national standards, and it is widely used in high-end hotels, airplanes, high-speed rail and other fields.

玉米淀粉餐具对人体健康友好,不含有害物质可以放心长期使用。玉米淀粉基生物可降解性餐具是人类生存环保的无公害绿色产品,国际上倡导,国内政策大力支持。由于它是玉米淀粉和纤维素等材料精制而成,不含对人体有害的物质,无餐盒无异味,弥留淡淡玉米香气,可放心长期使用。

Corn starch tableware is friendly to human health and does not contain harmful substances, allowing for safe long-term use. Corn starch based biodegradable tableware is a pollution-free green product for human survival and environmental protection, advocated internationally and strongly supported by domestic policies. As it is refined from materials such as corn starch and cellulose, it does not contain harmful substances to the human body, has no food boxes or odors, and retains a faint corn aroma. It can be used with confidence for a long time.

玉米淀粉基餐具是目前市场上比较常见的可降解餐盒,淀粉的主要来源是玉米,所以有时叫玉米淀粉基,但这类餐盒其实是淀粉和传统石油基PP等的混合塑料,国外叫生物基。玉米淀粉基餐具是通过淀粉的生物降解而致使整个材料物理性能崩溃,但崩溃后的石油基PP还是不可降解的,降解率根据餐盒成分可达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 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 mixed plastic of starch and traditional petroleum based PP, which is called bio based abroad. Corn starch based tableware is caused by the biodegradation of starch, which leads to the collapse of the physical properties of the entire material. However, after the collapse, petroleum based PP is still non degradable, and the degradation rate can reach 40% -80% based on the composition of the food box. Therefore, it can only be considered a degradable food box, not a fully degradable one.

聚乳酸(PLA)是一种新型的生物降解材料,使用可再生的植物资源所提出的淀粉原料制成。淀粉原料经由糖化得到葡萄糖,再由葡萄糖及一定的菌种发酵制成高纯度的乳酸,再通过化学合成方法合成一定分子量的聚乳酸。理论上PLA是一种生物塑料,且结晶度低(材料的结晶度越低,负责生物降解的微生物就越容易对材料进行化学分解),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,同时聚合的过程会提高结晶度。这些因素都会PLA降解的时间变长。

Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials proposed from renewable plant resources. Starch raw materials are saccharified to obtain glucose, which is then fermented with certain strains to produce high-purity lactic acid. Then, a certain molecular weight of polylactic acid is synthesized through chemical synthesis methods. In theory, PLA is a bioplastic with low crystallinity (the lower the crystallinity of the material, the easier it is for the microorganisms responsible for biodegradation to chemically decompose 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.

目前,世界上环保禁塑的很多先行例如欧洲已经不用降解和完全降解来描述材质,而是用是否可堆肥来说明。因为可堆肥对降解的时间,降解后的颗粒大小,降解后成分对植物生长的影响都能进行限定,来保证材质的性。

At present, many leading countries in the world that prohibit environmental plastic production, such as Europe, no longer use degradation and complete degradation to describe materials, but rather use whether they can be composted. Because compost 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.
