玉米淀粉餐盒是從玉米中提煉出的淀粉、纖維素等為主要原料,經過高溫脫水后,通過壓片機壓成同等寬度同等厚度的片狀材料,經高科技生產工藝加工而成的環保餐盒。優于餐盒本身屬生物降解制品,自然條件即可自行降解,避免了對環境的污染,節約了石油等資源,經權威檢測部門檢測,各項衛生指標均達到標準,高檔賓館、飛機、高鐵等領域都在廣泛使用。

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.

玉米淀粉餐具對人體健康友好,不含有害物質可以放心長期使用。玉米淀粉基生物可降解性餐具是人類生存環保的無公害綠色產品,國際上倡導,國內政策大力支持。由于它是玉米淀粉和纖維素等材料精制而成,不含對人體有害的物質,無餐盒無異味,彌留淡淡玉米香氣,可放心長期使用。

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場上比較常見的可降解餐盒,淀粉的主要來源是玉米,所以有時叫玉米淀粉基,但這類餐盒其實是淀粉和傳統石油基PP等的混合塑料,國外叫生物基。玉米淀粉基餐具是通過淀粉的生物降解而致使整個材料物理性能崩潰,但崩潰后的石油基PP還是不可降解的,降解率根據餐盒成分可達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)是一種新型的生物降解材料,使用可再生的植物資源所提出的淀粉原料制成。淀粉原料經由糖化得到葡萄糖,再由葡萄糖及一定的菌種發酵制成高純度的乳酸,再通過化學合成方法合成一定分子量的聚乳酸。理論上PLA是一種生物塑料,且結晶度低(材料的結晶度越低,負責生物降解的微生物就越容易對材料進行化學分解),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,同時聚合的過程會提高結晶度。這些因素都會PLA降解的時間變長。

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,世界上環保禁塑的很多先行例如歐洲已經不用降解和完全降解來描述材質,而是用是否可堆肥來說明。因為可堆肥對降解的時間,降解后的顆粒大小,降解后成分對植物生長的影響都能進行限定,來保證材質的性。

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.
