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(jīng)過高溫脫水后,通過壓片機(jī)壓成同等寬度同等厚度的片狀材料,經(jīng)高科技生產(chǎn)工藝加工而成的環(huán)保餐盒。優(yōu)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(duì)環(huán)境的污染,節(jié)約了石油等資源,經(jīng)權(quán)威檢測(cè)部門檢測(cè),各項(xiàng)衛(wèi)生指標(biāo)均達(dá)到標(biāo)準(zhǔn),高檔賓館、飛機(jī)、高鐵等領(lǐng)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(duì)人體健康友好,不含有害物質(zhì)可以放心長(zhǎng)期使用。玉米淀粉基生物可降解性餐具是人類生存環(huán)保的無(wú)公害綠色產(chǎn)品,國(guó)際上倡導(dǎo),國(guó)內(nèi)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(duì)人體有害的物質(zhì),無(wú)餐盒無(wú)異味,彌留淡淡玉米香氣,可放心長(zhǎng)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(chǎng)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(shí)叫玉米淀粉基,但這類餐盒其實(shí)是淀粉和傳統(tǒng)石油基PP等的混合塑料,國(guó)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(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 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(jīng)由糖化得到葡萄糖,再由葡萄糖及一定的菌種發(fā)酵制成高純度的乳酸,再通過化學(xué)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(jié)晶度低(材料的結(jié)晶度越低,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)。

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(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 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.
