Why is hydrogen peroxide stored in dark plastic bottles?

Hydrogen peroxide decomposes into water and oxygen, and the decomposition is catalysed by light and by traces of metal or alkali from a glass surface. A dark bottle keeps out the light and a plastic or wax-lined bottle avoids the catalytic effect of glass; a trace of acid or acetanilide is also added as a stabiliser.
