A. Rossi et al., MODIFICATION OF BARRIER PROPERTIES OF POLYMERIC FILMS OF LDPE AND HDPE BY COLD-PLASMA TREATMENT, Journal of polymer engineering, 14(2-3), 1995, pp. 191-197
In the present work barrier properties of low density polyethylene (LD
PE) and high density polyethylene (HDPE) films have been modified by a
rgon cold plasma surface treatments. This kind of treatment is commonl
y used to produce modifications on the surface layers of the polymer.
The effect on LDPE and HDPE films has been a decrease in the permeabil
ity values, with a consequent improvement of their barrier properties.
Such effects are strictly related to the operative parameters of the
plasma apparatus, transport gas, electrical characteristics and polyme
r structure.
