It keeps its contents colder, for longer

Ever noticed that your favourite soft drinks always seem just a little more refreshing than their counterparts in other packaging? It may be more than your imagination! Plastic and metals are good conductors of temperature, meaning that cold beverages placed in these materials will warm up more quickly if left out at room temperature or held in a warm hand. Glass, on the other hand, is a poor conductor – so your drink will stay colder for longer, for maximum refreshment.
