生物降解顆粒塑料是指一類由自然界存在的微生物如細菌、霉菌（真菌）和藻類的做用而引起降解的塑料。理想的生物降解顆粒塑料是一種具有優良的使用性能、廢棄后可被環境微生物完全降解、終被無機化而成為自然界中碳素循環的一個組成部分的高分子材料。

Biodegradable granular plastics refer to plastics degraded by natural microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable granular plastic is a kind of polymer material with excellent performance, which can be completely degraded by environmental microorganisms after being discarded, and finally become an integral part of the carbon cycle in nature.

“紙”是一種典型的生物降解顆粒材料，而“合成塑料”則是典型的高分子材料。因此，生物降解顆粒塑料是兼有“紙”和"合成塑料"這兩種材料性質的高分子材料。

"Paper" is a typical biodegradable granular material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable granular plastic is a polymer material with the properties of both "paper" and "synthetic plastic".

性GB/T20197-202X對降解塑料的定義是，在自然界各種條件下，終完全降解變成二氧化碳（CO2）或/和甲烷、水（H2O）及其所含元素的礦化無機鹽以及新的生物質的一種塑料。

The recommended international GB/T20197-202X defines degradable plastics as a kind of plastics that will eventually be completely degraded into carbon dioxide (CO2) or/and methane, water (H2O) and the mineralized inorganic salts of the elements it contains, as well as new biomass under various natural conditions.

生物降解顆粒塑料在大自然如土壤和/或沙土等條件下，或特殊條件如堆肥化條件下或厭氧消化條件下或水性培養液中，由大自然存在的微生物作用引起溶解，并溶解變成二氧化碳（CO）或/和甲烷（CH）、水（HO）及其所含元素的礦化碳酸鹽以及新的生物質的塑料。

Biodegradable granular plastics are dissolved under natural conditions, such as soil and/or sandy soil, or under special conditions, such as composting, anaerobic digestion, or aqueous culture medium, by microorganisms existing in nature, and dissolved into carbon dioxide (CO) or/and methane (CH), water (HO), mineralized carbonate of its elements, and new biomass plastics.

生物降解顆粒塑料主要的市場定位是塑料包裝制品塑料薄膜、農用塑料薄膜、一次性包裝袋和一次性塑料餐具。對比傳統塑料包裝制品材料，新型降解材料成本費稍高。但是伴隨著環境保護意識的增強，人們愿意為保護生態環境而使用稍高的新型降解材料，環境保護意識的增強給生物降解新材料行業帶來了很大的發展機遇。

The main market positioning of biodegradable granular plastics is plastic film for plastic packaging products, agricultural plastic film, disposable packaging bags and disposable plastic tableware. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the enhancement of environmental protection awareness, people are willing to use new biodegradable materials with higher prices to protect the ecological environment. The enhancement of environmental protection awareness has brought great development opportunities to the biodegradable new materials industry.

此外生物降解顆粒材料的降解性能是它的關鍵技術指標，如果達不到相應的要求的話，肯定會影響成品質量的。因此，對于想要購買的客戶朋友來說，弄清楚生物降解顆粒材料的降解性能怎么檢測就很關鍵了，具體的內容就來我們網站http://tecnoleo.com咨詢看看吧！

In addition, the degradation performance of biodegradable granular materials is its key technical indicator. If it fails to meet the corresponding requirements, it will definitely affect the quality of finished products. Therefore, for customers who want to buy, it is crucial to find out how to test the degradation performance of biodegradable particulate materials.
