玉米餐具是我们听说的“能吃的餐具吗？”

The so-called "corn tableware" is actually made of PLA (biodegradable plastic polylactic acid) extracted from corn starch, so if you want to understand corn tableware, you should start with PLA. PLA, the full name of polyacticacid, belongs to the polyester family. It is a polymer polymerized with lactic acid as the main raw material. The common polylactic acid materials have very good thermal stability, can withstand the high temperature of 170-230 ℃, and have certain bacterial resistance, flame retardancy and UV resistance. It is commonly used in medical and health fields (surgical suture, orthopedic fixation and tissue repair materials, surgical clothing, surgery) Covering cloth, etc.). In addition, the whole production process of polylactic acid is pollution-free and can be biodegraded in nature. It is an ideal new green polymer material.

PLA拥有三大特性：害、耐高温、可降解。在婴童用品种类繁杂、多方观点各执己见的今天，当三聚氰胺奶粉有毒、婴幼儿服装含荧光剂、婴儿米粉化学物质超标等新闻成为各大报纸杂志头条之时，妈妈们的担心又多了一层。当母乳无法满足宝宝营养需求时，不断出现在生活中的餐具更是重中之重。创立者更初看上PLA材质的特性就是它的医疗用途，经过不断地研究和改进，才形成了真正能够制作玉米餐具的聚乳酸颗粒。

PLA has three characteristics: non toxic, high temperature resistant and degradable. In today's complex variety of baby and children's products and different opinions, when the news of melamine milk powder poisoning, infant clothing containing fluorescent agents, baby rice flour chemicals exceeding the standard and other news become the headlines of major newspapers and magazines, mothers' worry has increased. When breast milk can not meet the nutritional needs of the baby, the tableware that constantly appears in life is the most important. At first, the founder thought that the characteristic of PLA material was its medical use. After continuous research and improvement, it was formed that the PLA particles could really make corn tableware.

其实“可以吃的餐具”不过是宣传方面常用的夸张手法，其真实含义来自于玉米餐具的害。众所周知，塑料餐具遇高温易挥发有毒物质、颜色中含有铅元素也产生毒性；不锈钢餐具通常容易有重金属元素超标的问题；搪瓷及玻璃餐具易碎易脱落；木质餐具更是由于难于清洗而附着太多细菌，这一切在玉米餐具身上都不存在。玉米餐具所用的PLA是从自质的玉米中提炼的淀粉发酵成乳酸后聚合而成的，制作过程中不添加任何对人体有害的添加剂。

In fact, "edible tableware" is just a common exaggeration in propaganda, and its real meaning comes from the non-toxic of corn tableware. As we all know, plastic tableware is easy to volatilize toxic substances when exposed to high temperature, and lead element is contained in the color. Stainless steel tableware is usually prone to the problem of excessive heavy metal elements; enamel and glass tableware are fragile and easy to fall off; wood tableware is difficult to clean and attach too many bacteria, all of which do not exist on corn tableware. PLA used in corn tableware is made by fermentation of starch extracted from the best natural corn into lactic acid, and no additives harmful to human body are added in the production process.

在使用过程中，由于聚乳酸中含有极微量的乳酸或低聚物，这些物质将在材料表面浸出一部分，让材料表面与人的肌肤同样保持弱碱性，防止了细菌与霉菌等微生物的附着和繁殖，清洗起来也格外方便。面对妈妈们习惯用高温进行用品的习惯，PLA材质的耐高温性也得到了良好的发挥，纯玉米婴童餐具可以经受住130℃的高温，沸水与微波炉加热都不会对餐具造成影响，更不会挥发出氮化物及硫化物等有毒物质。

In the process of use, because the polylactic acid contains a very small amount of lactic acid or oligomer, these substances will leach part of the material surface, so that the surface of the material and human skin remain weak alkaline, prevent bacteria and mold and other microorganisms from adhering and reproducing, and it is convenient to clean. Faced with the mother's habit of disinfecting articles with high temperature, the high temperature resistance of PLA material has also been given good play. The pure corn baby tableware can withstand the high temperature of 130 ℃. Boiling water disinfection and microwave heating will not affect the tableware, and will not volatilize toxic substances such as nitrides and sulfides.

当然，还有很多人认为，“可降解物质”就等于“脆弱的物质”，这是一种毫无依据的猜测。可降解要满足三个条件：充足的水气(相对湿度90%以上)、充足的氧气(非密闭循环)和适当的温度(58~70℃)，所以在我们日常生活中，纯玉米餐具是很难由于摆放或使用时间过长而有所消耗。不过，纯植物的PLA材质在坚固性方面还是有一定缺陷的，我们的产品面对的是经常失控的婴幼儿，摔落和磕碰在所难免，因此在生产初期就会添加害的矿物质以增加原材料的坚固度，使它比一般的塑料餐具更坚固更结实。

Of course, there are still many people who believe that "degradable substances" are "fragile substances", which is a groundless conjecture. Degradability should meet three conditions: sufficient moisture (relative humidity above 90%), sufficient oxygen (non closed cycle) and appropriate temperature (58 ~ 70 ℃), so in our daily life, pure corn tableware is very difficult to be consumed due to the long time placed or used. However, there are still some defects in the firmness of pure plant PLA materials. Our products are often out of control of infants and young children, falling and bumping are inevitable. Therefore, in the early stage of production, non-toxic minerals will be added to increase the firmness of raw materials, making it stronger and stronger than ordinary plastic tableware.
