Oxygen permeability of novel organic-inorganic hybrid coatings.

The oxygen transport properties of LDPE films coated with different kinds of hybrid coatings were then obtained in terms of permeability and diffusivity at 35 and 50 °C, and their correlation to various structural and processing parameters is discussed. In this contribution, in particular, we report data obtained at different organic/inorganic (O/I) ratios and for different PE-PEG molecular weights. A second paper of this series re- ports the effects induced in the oxygen permeability by changing the organic phase composition with hydrogen bonding capable organics and by treating with plasma the LDPE surface prior to coating
