The document discusses materials used for kids and toys. It explains that kids' imagination allows any material to be used for a toy. From a manufacturing perspective, toys must be able to be mass produced. In the past, toys were limited to traditional materials and processes, but now a global market drives the use of new materials and technologies. Materials can stimulate the senses through touch, sight, hearing, smell and taste. Some materials have functional purposes while structural integrity is the most important characteristic. Safety is also an important consideration when selecting materials for kids' toys.

“Functional” and

Some of the
materials herein
indicated are
functional, because
used to exploit some
well defined
characteristics;
anyway the most
important
characteristic of a

“structurality”,
because materials,
first of all, must
