Microscopic close-up of aluminium foil on the back of an intumescent rubber strip. Aluminium foil has a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 μm (0.24 mils) are also commonly used. [8] Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy-duty household foil is typically 0.024 mm (0.94 mils).
Silver is also applied to copper by means of electroplating, and provides an interior finish that is at once smooth, more durable than either tin or nickel, relatively non-stick and extremely thermally efficient. Copper and silver bond extremely well owing to their shared high electro-conductivity. Lining thickness varies widely by maker, but ...
The closure is supplied to the bottler with an aluminum foil layer liner already inserted. Although there are various liners to choose from, a typical induction liner is multi-layered. The top layer is a paper pulp that is generally spot-glued to the cap. The next layer is wax that is used to bond a layer of aluminum foil to the pulp.

A paper cup is a disposable cup made out of paper and often lined or coated with plastic [1] [2] or wax to prevent liquid from leaking out or soaking through the paper. [3] [4] Disposable cups in shared environments have become more common for hygienic reasons after the advent of the germ theory of disease.
The use of liners is also considered a more sanitary option when cupcakes are being passed from hand to hand. Like cupcake pans, several sizes of paper liners are available, from miniature to jumbo. In addition to paper, cupcake liners may be made from very thin aluminum foil or, in a reusable version, silicone rubber.
