| Abstract: | The ageing of the material for the greenhouse film is studied. Little stabilizer, antioxdant, metalionic passivator and other additives are added in the material. The experiment results of the artifi-cial accelerated weathering and the naturally weathering confirm that the using life of this filmwillbe 1.5~ 2 years,which is 3~4 times longer than common films. |
