可降解塑料颗粒主要由天然聚合物（如淀粉、纤维素、甲壳素）或农副产品经微生物发酵或合成可生物降解的聚合物制成，如热塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等.属于这类塑料，主要用于制造可降解塑料。可降解塑料是指性能能满足使用要求的一类产品，在储存期间性能保持不变，但使用后在自然条件下可降解为对环境无害的物质的塑料。下面下介绍可降解塑料颗粒的相关知识。

Degradable plastic particles are mainly made of natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch / polyvinyl alcohol, etc It belongs to this kind of plastics and is mainly used to manufacture degradable plastics. Degradable plastic refers to a kind of product whose performance can meet the use requirements. Its performance remains unchanged during storage, but it can be degraded into environmentally friendly substances under natural conditions after use. The following describes the relevant knowledge of degradable plastic particles.

Photodegradable plastics, biodegradable plastics, light, oxidative biodegradable plastics, carbon dioxide based biodegradable plastics, thermoplastic starch resin degradable plastics.

可降解颗粒厂家提醒，降解过程主要涉及生物降解、光降解和化学降解，这三种主要降解过程相互之间具有协同、协同和连贯的作用。例如，光降解和氧化物降解往往同时发生，相互促进；在光降解过程之后更有可能发生生物降解。

Manufacturers of degradable particles remind that the degradation process mainly involves biodegradation, photodegradation and chemical degradation, and these three main degradation processes have synergistic, synergistic and coherent effects on each other. For example, photodegradation and oxide degradation often occur simultaneously and promote each other; Biodegradation is more likely to occur after the photodegradation process.
