So LLDPE powder material should not be processed to degradable plastics by adding photo-sensitizers.
因此，LLDPE粉料不适于添加光敏化剂加工成可控降解塑料。

Plastics degradation is the combination of photo-degradation and biodegradation, beginning with the photo-degradation and metabolized by biodegradation and turning into humic substance, H_2O and CO_2.
