Why does flex have a thin layer of plastic on outside
The thin layer of plastic in flex is a protective coating that helps to prevent the flex from creasing or bending too much, which can damage the electrical components inside. It also helps to provide a smooth surface for the electrical traces to adhere to, ensuring a reliable connection and preventing shorts.

The thin, solid, outermost layer of the Earth is officially known as the crust.
All water starts to turn to ice at 0 degrees Celsius or 32 degrees Fahrenheit. it just depends how long you leave it to freeze. it usually takes about half an hour for a very thin layer of ice to appear on the top however it doesnt just freeze at the top, it freezes on the whole outside of the water so even if the top is a thin layer of ice after about an hour, there is a high chance that it is also frozen the whole of the outside to form like an ice container however the ice is very weak and even slightly touching it will cause it to break. hope this helps :)

it does not have a cloth covering. on the outside it is a thin coat of plastic then leather.
It is called laminating or laminate flooring.
Pure aluminium foil (not mylar), has three layers, a protective oxide coating on each face of the foil, and pure metal inbetween. Mylar is a metallised plastic, one variety has a polyethlene terephthalate film coated on both sides with a thin layer of aluminium. From a microscopic view the aluminium layer has a protective layer of oxide.
