聚乳酸(可降解塑料)則是另一種應(yīng)用廣泛的可生物降解聚合物樹脂，和PBAT具有完全相反的力學(xué)性能，因此，利用共混法將兩者制成共混物是性能互補的有效手段，且所得共混材料和制品具有完全的可生物降解性。

Polylactic acid (degradable plastic) is another widely used biodegradable polymer resin, which has completely opposite mechanical properties to PBAT. Therefore, blending the two into a blend by blending method is an effective means to complement each other, and the resulting blend materials and products have complete biodegradability.

聚乳酸(可降解塑料PLA)是一種新型的可降解塑料，由可再生植物資源(如玉米)衍生的淀粉制成。將淀粉原料糖化得到葡萄糖，然后將葡萄糖和一定的發(fā)酵生產(chǎn)高純度的乳酸，再通過化學(xué)合成的方法合成一定分子量的聚乳酸。它具有良好的生物降解性，使用后可被自然界的微生物完全降解，終生成二氧化碳和水，不污染環(huán)境，非常有利于環(huán)境保護，是公認的環(huán)保材料。

Polylactic acid (PLA) is a new type of degradable plastic, which is made of starch derived from renewable plant resources (such as corn). Glucose is obtained by saccharifying starch raw materials, and then glucose and a certain amount of fermentation are used to produce high-purity lactic acid, and then polylactic acid with a certain molecular weight is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by natural microorganisms, and finally generate carbon dioxide and water. It does not pollute the environment. It is very conducive to environmental protection. It is recognized as an environmental protection material.

普通塑料的處理方法仍然是焚燒和火化，造成大量溫室氣體排放到空氣中，而聚乳酸塑料則埋在土壤中降解，產(chǎn)生的二氧化碳直接進入土壤有機質(zhì)或被植物吸收，不會排放到空氣中，不會造成溫室效應(yīng)。

The treatment method of ordinary plastics is still incineration and cremation, resulting in a large number of greenhouse gases discharged into the air, while polylactic acid plastics are buried in the soil for degradation, and the generated carbon dioxide directly enters the soil organic matter or is absorbed by plants, which will not be discharged into the air and will not cause temperature chamber effect.

良好的機械和物理性能。聚乳酸適用于吹塑、熱塑性塑料等各種加工方法。從工業(yè)到民用，可用于加工各種塑料制品、包裝食品、快餐飯盒、無紡布、工業(yè)和民用織物。然后加工成農(nóng)用面料、保健面料、抹布、衛(wèi)生用品、戶外防紫外線面料、帳篷面料、地墊等，市場前景十分廣闊。

Good mechanical and physical properties. Polylactic acid is suitable for blow molding, thermoplastic and other processing methods. From industry to civil use, it can be used to process all kinds of plastic products, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics. Then it is processed into agricultural fabrics, health fabrics, rags, sanitary products, outdoor anti ultraviolet fabrics, tent fabrics, floor mats, etc. the market prospect is very broad.

良好的相容性和降解性。聚乳酸在醫(yī)學(xué)上的應(yīng)用也很廣泛，例如可用于生產(chǎn)一次性輸液工具、可拆卸手術(shù)縫合線，低分子量聚乳酸用作的緩釋包裝劑。

Good compatibility and degradability. Polylactic acid is also widely used in medicine. For example, it can be used to produce disposable infusion tools, detachable surgical sutures, and low molecular weight polylactic acid can be used as sustained-release packaging agent.

雖然可降解顆粒的塑料目前在塑料總規(guī)模中的占比還微乎其微，但是產(chǎn)業(yè)也已經(jīng)發(fā)展了多年，其中哪些品種受市場重視實際已經(jīng)有了，不過我們還是希望深入分析其中的原因，以便對未來展望。PLA與其他可降解塑料相比，在一些方面并沒有優(yōu)勢，但是硬度和透明性上PLA卻具有的性能。

Although the proportion of degradable granular plastics in the total scale of plastics is still very small, the industry has also developed for many years, and which varieties have been paid attention to by the market. However, we still hope to deeply analyze the reasons in order to look forward to the future. Compared with other degradable plastics, PLA has no advantages in some aspects, but it has better properties in hardness and transparency.
