一種是非全降解塑料。一般為PE＋淀粉或PE＋崩解劑的組成，很多公司有銷售。這種材料在使用后淀粉的部分會很快分解，但PE的部分還是很難降解。不過，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。崩解劑也不能使PE完全降解，只是在使用后使薄膜碎裂成小塊。因此，這種材料問不能稱為降解材料，根據(jù)我國可降解材料標(biāo)準(zhǔn)GB/T20197-2006的規(guī)定，其并不在列。一般很便宜，與現(xiàn)有的PE差異答不大。

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.

另外一種是全降解塑料。一般分為聚羥基酸、專聚二酸二醇兩類。聚羥基酸包括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以及改性過的PLA等。這類材料普遍比較貴，通常要四到六萬一噸，國內(nèi)消費(fèi)者比較難接屬受。為了降低成本，也有廠商在這類材料中加入淀粉等物質(zhì)，但性能會有降低，成本的下降也不是十分明顯。

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.

此外可降解顆粒塑料的包裝實(shí)際上是用可生物降解的袋子代替了傳統(tǒng)的包裝，一開始比原來的塑料袋和紙袋便宜，環(huán)保指數(shù)比原來的塑料袋高。讓這種新材料替代我們的傳統(tǒng)材料，創(chuàng)造環(huán)保地球，讓消費(fèi)者更好地享受購物體驗(yàn)。

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.

由兩種不同材料制成的可降解環(huán)保包裝袋。一種是由可再生原料（如甘蔗渣、淀粉等）制成，稱為“環(huán)保再生原料包裝袋”。另一種是以光熱發(fā)電為標(biāo)準(zhǔn)，由可降解原料制成的包裝袋中的分子相互作用。這種綠色包裝也被稱為“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"

可降解顆粒材料的原料主要用于包裝、合成纖維、農(nóng)業(yè)和進(jìn)口等。在這些包裝中，較為常見，主要用于包裝。它的監(jiān)管已大大改善，包括產(chǎn)品、包裝、農(nóng)業(yè)和紡織品。在其他領(lǐng)域，也使用可生物降解的原料。特別是在歐洲，鼻假體的診斷和以及藥物系統(tǒng)。

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.
