生物降解顆粒的降解原理是怎樣的呢？實(shí)際上，生物降解塑料添加劑包含一種天然纖維質(zhì)添加成分，該成分呈細(xì)小的顆粒形狀；既具有可生物降解特性又具有較高的透明度，從而對終端產(chǎn)品的物理性能影響甚微。該生物降解添加劑系列，是以聚烯烴為載體，配以一種天然植物纖維素的復(fù)合物。

What is the degradation principle of biodegradable particles? In fact, the biodegradable plastic additive contains a natural fibrous additive, which is in the shape of fine particles; It has both biodegradability and high transparency, so it has little impact on the physical properties of the end product. This series of biodegradable additives is a composite of polyolefin as carrier and natural plant cellulose.

另外，該復(fù)合物中還包含一種金屬離子預(yù)降解成分，以便為聚合物引發(fā)光降解的特性。所有的添加成分對環(huán)境都無害。含有生物降解添加劑的塑料薄膜具有生物降解的特性。

In addition, the composite also contains a metal ion pre degradation component, so as to generate light degradation characteristics for the polymer. All additives are harmless to the environment. The plastic film containing biodegradable additives has the characteristics of biodegradation.
