Peel Strength Measurements of Al-Plasma Modified PP Systems

Peel Strength Measurements of Al-Plasma Modified PP Systems 

Unspecifically oxygen-plasma modified PE and PP surfaces show maximum peel strength values respectively for a degree of oxidation of 20 0/100 C atoms (Fig. 18.6). 

No difference was measured between the A1 peel strength of PP after specific or unspecific plasma pretreatment (Table 18.2). This was interpreted roughly by comparing the average of the polarities of different O functional groups pro-
