（1）聚乳酸改性塑料是一种新型生物降解材料

（2）良好的机械和物理性能。聚乳酸适用于各种加工方法，如吹塑成型和热塑性塑料，易于加工，应用广泛

（3）良好的相容性和降解性。聚乳酸还广泛应用于医药领域，如一次性输液设备、不可拆卸外科缝线等的生产，以及作为缓释药物包装剂的低分子量聚乳酸

除了生物可降解塑料的基本特性外，聚乳酸改性塑料也有其独特的特性。传统生物降解塑料的强度、透明度和抗气候变化能力不如普通塑料

（5）聚乳酸改性塑料和石油化工合成塑料的基本物理性能相似，可以广泛用于制造各种应用产品。聚乳酸还具有良好的光泽和透明度，与聚苯乙烯薄膜相当，其他生物降解产品无法提供

聚乳酸改性塑料具有最好的拉伸强度和延展性。聚乳酸也可以用各种常见的加工方法生产

（7）聚乳酸薄膜具有良好的透气性、透氧性和透二氧二甲碳性，并具有隔离异味的特性

（8）当聚乳酸被焚烧时，其燃烧热值与焚烧纸相同，是传统塑料（如聚乙烯）的一半。此外，焚烧聚乳酸不会释放氮化物和硫化物等有毒气体。人体还含有单体形式的乳酸，这表明这种可分解产品的安全性

聚乳酸改性塑料的缺点：

（1）聚乳酸含有大量酯键，亲水性差，降低了其与其他物质的生物相容性

（2）聚合得到的产物相对分子量分布过宽，而聚乳酸本身是线性聚合物，这使得聚乳酸材料的强度往往无法满足要求，脆性高，热变形温度低（在0146MPa载荷下为54°C），抗冲击性差

（3）降解周期难以控制

价格太贵，乳酸的价格和聚合工艺决定了PLA的更高成本

Polylactic Acid Modified Plastic

Product Details

Polylactic acid modified plastic advantages:

(1) Polylactic acid modified plastic is a new type of biodegradable material.

(2) Good mechanical and physical properties. Polylactic acid is suitable for various processing methods such as blow molding and thermoplastic, and is easy to process and has a wide range of applications.

(3) Good compatibility and degradability. Polylactic acid is also widely used in the field of medicine, such as the production of disposable infusion equipment, non-disassembly surgical sutures, etc., and low-molecular-weight polylactic acid as a slow-release drug packaging agent.

(4) In addition to the basic characteristics of biodegradable plastics, polylactic acid modified plastics also have their own unique characteristics. The strength, transparency and resistance to climate change of traditional biodegradable plastics are not as good as ordinary plastics.

(5) The basic physical properties of polylactic acid modified plastics and petrochemical synthetic plastics are similar, that is to say, it can be widely used to manufacture various application products. Polylactic acid also has good gloss and transparency, which is comparable to films made of polystyrene, and cannot be provided by other biodegradable products.

(6) Polylactic acid modified plastic has the best tensile strength and ductility. Polylactic acid can also be produced in various common processing methods.

(7) The polylactic acid film has good air permeability, oxygen permeability and dioxydicarbon permeability, and it also has the characteristics of odor isolation.

(8) When polylactic acid is incinerated, its heat value of combustion is the same as that of incineration paper, which is half of that of traditional plastics (such as polyethylene). In addition, incineration of polylactic acid will never release toxic gases such as nitrides and sulfides. The human body also contains lactic acid in the form of monomer, which shows the safety of this decomposable product.

Polylactic acid modified plastic Disadvantages:

(1) Polylactic acid has a large number of ester bonds, which has poor hydrophilicity, which reduces its biocompatibility with other substances;

(2) The relative molecular weight distribution of the product obtained from the polymerization is too wide, and the polylactic acid itself is a linear polymer, which makes the strength of the polylactic acid material often unable to meet the requirements, high brittleness, and low heat distortion temperature (54°C under a load of 0146MPa) , Poor impact resistance;

(3) The degradation cycle is difficult to control;

(4) The price is too expensive, the price of lactic acid and the polymerization process determine the higher cost of PLA.
