Aluminum Foil - From Science E-notes
"Extracting pure aluminum from bauxite entails two processes. First, the ore is refined to eliminate impurities such as iron oxide, silica, titania, and water. Then, the resultant aluminum oxide is smelted to produce pure aluminum. After that, the aluminum is rolled to produce foil."

From Alcoa manufacturers website ay www.alcoa.com
Semitransparent paper with a thin coating of wax on both sides.
Wax Paper is manufactured with a triple coating of paraffin wax onto tissue paper. The wax is both forced into the pores of the paper and spread over the outside as a coating.

Capacitance is k*epsilon*A/d, where A is the surface area, epsilon is 8.85*10^-12, k is your relative dielectric constant (2.5 in your case), and d is the distance of separation between your conductors.
