Recently the usage of tissue-foil on folding origami models have become more common due to creation of more complicated folding techniques that demand a more reliable approach to get the optimum effect of the finished subject. So what is actually tissue-foil.

Basically, tissue-foil is just aluminum foil laminated two sides with tissue paper or crepe paper with the help off spray adhesive or water glue. It has no traces of paper in it making it strong and flexible, yet easy to fold.Spray adhesive can be purchased from regular DIY stores (I go for ones on the shelves on $2 shops!) It's rather quick for the adhesive to set and will not wet the paper, however some disadvantages of using the spray are its awful smell. I would advice to guys to cover your noses while spraying, as the smell could cause cancer of the lungs. It might help to work outside.
The right procedure on laminating tissue on the foil should be done on the floor covered with old newspapers. Ensure that there are no obstructions round the area. Place the foil on the newspaper then with the adhesive can; stand at a mere range of 30cm from the surface aiming towards it at a 45 degree angle. Get the tissue and hold the edge of the tip of the top corners with both hands. While bringing the tissue to contact with the foil, lightly stretch the tissue (be careful not to tear it) and lap it over the foil. The reason for this is to ensure that no messy creases occur upon the tissue, being its very delicate. Once the tissue is on the foil and everything is in place, take a flat large object to press the tissue on the surface, (an old telephone directory might come in handy for this). Remove the object and gently remove the tissue-foil in contact with the newspaper. Then follow the similar procedures for laminating the otherside of the foil with the tissue.
Water glue can also be applied by mixing 1/2 a tube in a spray bottle with water. This method is very economical and environment friendly. But the only thing is that here could be some wrecks on the tissue and it may quite difficult to laminate it due to the wetness of the glue. Another disadvantage to this method, is that the glue takes some time to set (1 hour at least) before you can work on the paper.
