玉米餐具是我們聽（tīng）說的“能吃的餐具嗎？”

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擁有三大特性：害、耐高溫、可降（jiàng）解。在嬰童用品種類繁雜、多方（fāng）觀（guān）點各執己見的今天（tiān），當三聚氰胺奶粉有毒、嬰幼兒服裝含（hán）熒光劑、嬰兒米粉化學物質超（chāo）標等新聞成為（wéi）各大報紙雜誌頭條之時（shí），媽媽們的擔心（xīn）又多了一層。當母乳無法滿（mǎn）足寶寶營養需求（qiú）時（shí），不斷出現在生活中的餐具更是重中之重。創立者更初看上PLA材質的特性就是它的（de）醫（yī）療用途，經過不斷（duàn）地研究（jiū）和改進，才形成了真（zhēn）正能夠製作玉米餐具（jù）的聚乳酸顆粒。

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（qí）實“可以吃的餐具”不過是宣傳方麵常用的誇張手法，其真實含（hán）義來自於玉米餐具的害。眾所周知，塑料餐具遇高溫易揮（huī）發有毒物質、顏色中含有鉛元素也產生毒性；不鏽鋼餐具通常容易有重金屬元素超標的問題；搪瓷及（jí）玻璃（lí）餐具易（yì）碎易脫落；木質餐具更是由於難於（yú）清洗而附著太多細菌，這一切在玉米餐具身上都不存在。玉米餐具所用（yòng）的PLA是（shì）從自質的玉米中提煉的澱粉發酵成乳（rǔ）酸後聚合而成的，製作過程中不添（tiān）加任何對人體有害的添加劑。

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（yòng）過程（chéng）中，由於聚乳酸中含有極微量的乳酸或（huò）低聚物，這些物質將在材料表麵浸（jìn）出一部分（fèn），讓材料表麵（miàn）與人的肌（jī）膚同樣保持弱堿性，防止了細菌與黴菌等微（wēi）生物的附著和繁殖，清洗起來也格外方便。麵對媽（mā）媽們習慣用高溫進行用品的習慣，PLA材質的耐高溫性也得到了良好的發揮，純玉米嬰童（tóng）餐具可以經受住130℃的高溫，沸水與微波爐加熱都不會對餐具造成影響，更不會揮發出氮化物及硫化物等有毒物質（zhì）。

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.

當然，還有很多人認為，“可降解物質”就等於“脆弱的物質”，這（zhè）是一（yī）種毫無（wú）依據的猜測（cè）。可降（jiàng）解要滿足三個條件：充足的水氣(相對濕度90%以上)、充足的氧氣（qì）(非密閉循環)和適當（dāng）的溫度(58~70℃)，所以在（zài）我們日常生（shēng）活（huó）中，純玉米餐具（jù）是很難由於擺放或（huò）使用時間過長而有所消耗。不過，純植物（wù）的PLA材質在堅固性方麵還是有一定缺陷的，我（wǒ）們的產品麵對的是經常（cháng）失控的嬰幼兒，摔落和磕（kē）碰在所難免，因此（cǐ）在生產初期就會添加害的礦（kuàng）物質以增加原材料的堅固度，使它比一般的塑（sù）料餐（cān）具更堅（jiān）固更（gèng）結實。

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.
