Verfahren zur Herstellung von flexiblen Folien aus synthetischen thermoplastischen, rußfreien Materialien |
摘要 |
A thermoplastic film for controlling plant growth which has a total light transmittance to sunlight of less than 40% for light with a wavelength of 300 - 700 m mu and a light transmittance greater than 60% for wavelengths above about 900 m mu and preferably between 90 and 1,500 m mu . The foil or film thickness may be 0.01 to 0.5 mm and the light transmittance characteristics thereof correspond to the following table: |
