Effects of electron-beam irradiation on wettability and surface free energy of a polypropylene film

“…The value of SFE is commonly accepted as a measure of the thermodynamic state of the surface layer (SL) of a polymeric material and criterion for evaluation of changes occurring in this layer upon its modification [1][2][3]. In industry, polymers are being modified mainly by corona discharge in air or treatment with flame or low-temperature plasma, under the conditions of low pressure and atmosphere of suitable gas or gas mixture [4][5][6][7]. The modification processes are aimed mostly at changing the hydrophobic properties into hydrophilic ones, increasing the SFE values and, thus, improving adhesion properties of these materials.…”

Influence of electron radiation on adhesion of some polymer films to acrylic adhesives

“…Thus, modification of their surface layer is necessary, which is mostly being realized by means of corona discharge, flame or lowtemperature plasma treatment [4][5][6][7][8].…”

“…, especially BOPP, these variations may decrease the mechanical strength of the film, which would limit application of this film in packaging[18,19].…”
