Abstract.
As the contacting time between plastic packaging materials and food extended, PAEs can be gradually migrate from the plastic into the food [[] Jen-Fon Jen, Tzu-Chi Liu: Journal of Chromatography A, Vol. 28(2006), p. 28-33. ].

The major functions of geosynthetic materials are separation, reinforcement, filtration, drainage and acting as a liquid barrier.
The higher the IR, the higher the benefit from the reinforcing material [14].
