[edit] Distinguishing features
Plastic cups come in a variety of colours, textures and sizes.
Most plastic cups contain a resin identification code which can be seen by inverting the cup and reading the numerical value printed on the bottom.
[edit] Uses
Plastic cups are often used for gatherings where it would be inconvenient to wash dishes afterward, due to factors such as location or number of guests[citation needed]. Plastic cups can be used for storing most liquids, but hot liquids may melt the material.
[edit] Environmental issues
Most plastic cups are designed for single uses and then disposal or recycling. A life cycle inventory of a comparison of paper and plastic shows environmental effects of both with no clear winner. Production of one plastic cup emits 135 pounds of green house gases[1]
