- The paper dealt with the evaluation of the oxygen permeability of the polyethylene films applied in the mulching and food packaging. The construction of the equipment is discussed. The design and the construction of the equipment was realized with applying of the standard EN STN 77 0333.The measurement of the permeability of the oxygen trough the polyethylene Bralen 2-63 with 9% colored concentrate Maxithen HP 533041 - violet film was realized by means of modified method. The values of the permeability Px, 1794.25 cm3*m-2*d-1. (0.1 Mpa)-1 of the oxygen trough the film of the thickness of 50 µm was evaluated. The coefficient of permeability P, 4.2560*10-16 mol*m-1*s-1*Pa-1, coefficient of diffusion D, 4.3999*10-10 m2*s-1 and solubility coefficient of the gas in the film Sp, 9.6735*10-7 mol*m-3*Pa-1 were determined.
