Characterization on Optical and Mechanical Properties of Low-density Polyethylene Films Doped with Eu(III)complex Mohd.
The mechanical properties of the films were measured according to ASTM D882, and ASTM D1938 standards.
The important environmental factors affecting plant growth are temperature, relative humidity, light level, and carbon dioxide [3].Greenhouses are covered with transparent material that transmits visible light (400–700 nm), the main source of energy for photosynthesis and Lozano (1996)  emphasized the importance of good light permeability in increasing greenhouse crop production [4].
In addition, polyethylene possesses relatively good mechanical and optical properties, combined with a competitive market price [5,6].
This is due to the small percentage of the complex which does not affect the properties of the films in transverse orientation.
