可降解的塑料袋用什么颗粒粒子

一种是非全降解塑料。一般为PE＋淀粉或PE＋崩解剂的组成，很多公司有销售。这种材料在使用后淀粉的部分会很快分解，但PE的部分还是很难降解。不过，由度于淀粉分解后在材料中留下了空隙，在一定程度上可以加快PE的降解。崩解剂也不能使PE完全降解，只是在使用后使薄膜碎裂成小块。因此，这种材料问不能称为降解材料，根据我国可降解材料标准GB/T20197-2006的规定，其并不在列。一般很便宜，与现有的PE差异答不大。

One is non fully degradable plastic. Generally, it is composed of PE + starch or PE + disintegrating agent, which is sold by many companies. The starch part of this material will decompose quickly after use, but the PE part is still difficult to degrade. However, due to the gap left in the material after starch decomposition, the degradation of PE can be accelerated to a certain extent. The disintegrator can not completely degrade PE, but only breaks the film into small pieces after use. Therefore, this kind of material can not be called degradable material. According to the provisions of China's degradable material standard gb/t20197-2006, it is not listed. The price is generally very cheap, and there is little difference with the existing PE price.

另外一种是全降解塑料。一般分为聚羟基酸、专聚二酸二醇两类。聚羟基酸包括PLA、PHV、PHBV等等。聚二酸二醇包括PBS、PBSA、PBAT等等。可以直接做成塑料袋的有PHBV、PBS、PBSA、PBAT以及改性过的PLA等。这类材料普遍比较贵，通常要四到六万一吨，国内消费者比较难接属受。为了降低成本，也有厂商在这类材料中加入淀粉等物质，但性能会有降低，成本的下降也不是十分明显。

The other is fully degradable plastic. It is generally divided into polyhydroxy acid and special polydiacid glycol. Polyhydroxy acids include PLA, PHV, PHBV, etc. Polydiacid diols include PBS, PBSA, PBAT, etc. PHBV, PBS, PBSA, PBAT and modified PLA can be directly made into plastic bags. Such materials are generally expensive, usually 40 to 60 thousand tons, which is difficult for domestic consumers to accept. In order to reduce the cost, some manufacturers have added starch and other substances to this kind of materials, but the performance will be reduced, and the cost reduction is not very obvious.

此外可降解颗粒塑料的包装实际上是用可生物降解的袋子代替了传统的包装，一开始比原来的塑料袋和纸袋便宜，环保指数比原来的塑料袋高。让这种新材料替代我们的传统材料，创造环保地球，让消费者更好地享受购物体验。

In addition, biodegradable granular plastic packaging actually replaces the traditional packaging with biodegradable bags. At the beginning, it is cheaper than the original plastic bags and paper bags, and the environmental protection index is higher than the original plastic bags. Let this new material replace our traditional materials, create an environment-friendly earth, and let consumers better enjoy the shopping experience.

由两种不同材料制成的可降解环保包装袋。一种是由可再生原料（如甘蔗渣、淀粉等）制成，称为“环保再生原料包装袋”。另一种是以光热发电为标准，由可降解原料制成的包装袋中的分子相互作用。这种绿色包装也被称为“可降解塑料袋”

Degradable environmental protection packaging bag made of two different materials. One is made of renewable raw materials (such as bagasse, starch, etc.), which is called "environmental friendly renewable raw material packaging bag". The other is the molecular interaction in the packaging bag made of degradable raw materials based on the standard of photothermal power generation. This green package is also known as "degradable plastic bag"

可降解颗粒材料的原料主要用于包装、合成纤维、农业和进口等。在这些包装中，较为常见，主要用于包装。它的监管已大大改善，包括产品、包装、农业和纺织品。在其他领域，也使用可生物降解的原料。特别是在欧洲，鼻假体的诊断和以及药物系统。

The raw materials of degradable granular materials are mainly used for packaging, synthetic fiber, agriculture and import. Among these packages, they are common and mainly used for packaging. Its regulation has been greatly improved, including products, packaging, agriculture and textiles. Biodegradable raw materials are also used in other fields. Especially in Europe, the diagnosis and treatment of nasal prosthesis and drug treatment system.
