降解的堆肥袋条制成的降解，假定可降解的聚乙烯和不可降解的低密度和高密度聚乙烯在土壤中与50%（w/w）的成熟的城市固体废物堆肥提供的城市垃圾混合进行了评价。在室温下，将塑料膜埋在含有调节至最大持水量40%的土壤的2 L干燥罐中15个月。塑料的降解是通过样品的重量损失、拉伸强度、二氧化碳的产生、红外光谱中测量的化学变化和土壤中的细菌活性来确定的。所检测的薄膜可以按照敏感性降低的顺序排列：可降解聚乙烯>低密度聚乙烯>高密度聚乙烯。
A degradation of compost bags strips made of supposedly degradable polyethylene and nondegradable low density and high density polyethylene were evaluated in soil mixed with 50% (w/w) mature municipal solid waste compost supplied from municipal refuse. Plastic films were buried during 15 months at room temperature in 2 L desiccator jars containing soil adjusted to 40% of maximum water holding capacity. Degradation of plastics was determined by the weight loss of sample, tensile strength, carbon dioxide production, chemical changes measured in infrared spectrum and bacterial activity in soil. The examined films can be ranged in order of decreasing susceptibility: degradable polyethylene >>> low density polyethylene > high density polyethylene.
