Have you been to a party lately? You find that most of the parties are now extremely robust, fully decorated, and have a lot of guests coming over at all possible times. The parties will also cater to a lot of children, and food happens to be a common binding factor amongst everybody. If the party almost always comprises of adults, then alcoholic beverages is also going to make its presence felt.
Now, when it comes to decorating the party interiors and exteriors, proper plastic table covers are to be used. Well, the plastic table covers provide a lot of sheen and shine to the party. Without it, the party would look blank. However, if the plastic table covers do not have an oily surface, then you can be pretty sure that it is one to absorb the oil and alcoholic drinks that would be accidentally spilled on it.
It is also only a possibility that since you would not be able to wash the table cover and get rid of the stains, you would have to get rid of it by throwing it away. That is a loss that will only keep on mounting if it happens to almost all the plastic table covers in the party.
