玉米淀粉凭借绿色,使用后可自然降解的特性,受到了大众的关注!下面玉米淀粉颗粒餐具厂家就给大家普及一下这种餐具的两种材质,希望对大家有所帮助!

Corn starch with green, after use can be natural degradation characteristics, by the public's attention! The following corn starch granule tableware manufacturers will popularize the two kinds of tableware materials, hoping to help you!
玉米淀粉餐具主要分两种,看材质说明,一种是淀粉基,淀粉的主要来源是玉米,所以有时也叫玉米淀粉基,其实是淀粉和传统石油基PP等的混合塑料,国外叫生物基。是可以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。对比传统的餐具是比较环保,成本也差不多。
Corn starch tableware is mainly divided into two types. According to the material description, one is starch base. The main source of starch is corn, so sometimes it is also called corn starch base. In fact, it is a mixed plastic of starch and traditional petroleum based PP, which is called bio base abroad. It is the biodegradation of starch that leads to the collapse of the physical properties of the whole material, but the petroleum based PP is still not degradable after the collapse. Compared with the traditional tableware, it is more environmentally friendly, and the cost is almost the same.

另一种是PLA聚乳酸,1吨的聚乳酸是用3吨的玉米淀粉提取转化出来的,工艺流程复杂,所以价格也比较高,这种是完全可降解的。但是纯PLA是不耐高温的,所以市场上的完全降解餐具大多是改性PLA做的,也是添加完全生物降解的石油基PBAT等其他材料的。如果宣传完全降解,生物基部分和石油基部分都必 须是完全可降解的。
The other is PLA polylactic acid. 1 ton of polylactic acid is extracted and converted from 3 tons of corn starch. The process is complex, so the price is relatively high. This kind of polylactic acid is completely degradable. However, pure PLA is not resistant to high temperature, so most of the fully biodegradable tableware on the market is made of modified PLA, which is also added with fully biodegradable petroleum based PBAT and other materials. If the promotion of complete degradation, the bio based part and petroleum based part must be completely degradable.
严格意义上说,淀粉基混合PP那种从整体看不能称为可降解,或者部分可降解,因为整体放在堆肥环境中式没法降解的,只有分离出来才可以。欧洲已经不用降解,完全降解来描述材质,用可堆肥来说明,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进行限定,来保证材质的安 全性。
Strictly speaking, starch based Mixed PP can not be called degradable or partially degradable from the overall point of view, because it can not be degradable if it is put in composting environment as a whole, and it can only be separated. In Europe, it is no longer necessary to use degradation to describe the material completely, but compostable to describe it, because compostable can limit the degradation time, particle size after degradation, and the influence of components after degradation on plant growth, so as to ensure the safety of the material.
