Controlled multilayer degradable film

摘要

The present invention relates to multilayer degradable films for covering soil for use in cropping or covering a frame in order to achieve a greenhouse effect. In particular, the present invention is directed to a polyolefin film having a degradable component wherein degradation is activated by both ultraviolet and thermal triggers. More particularly, the degradable polyolefin film of the present invention changes color through selective layer degradation to suit the season and geographic location of the area being covered.
