I like the red onions in my toss salads. Seldom do i use a whole one, because they are usually so large and i want to know how can i keep the already cut onion from going bad. I have tried just about everything, zip lock bags, wrapping in foil or plastic wrap, brown paper bags etc. But for some reason and sometimes the onion becomes slimy on the cut part, at which point i have to cut away a portion of the onion before i can use it.

2If you stick it in the fridge/freezer (after covering it so that it's aroma doesn't affect other things), it should be fine. Onions stay for a long time in my fridge when covered up.– Dharini ChandrasekaranCommented Jun 21, 2012 at 22:42

Take a decent sized cling film, put the onion with the cut part down in the centre. Close the cling film over the round part and twist all the air out of the wrap.
The onion will stay good in the fridge for some days.

For fridge storage for a couple of days, the small amount of air in a re-usable plastic container will not hurt the onion. The container, or single use plastic wrap, is to stop onion gases contaminating the rest of the fridge– TFDCommented Aug 3, 2015 at 4:19
BaffedCook's answer responds to your question more directly. I'm suggesting a roundabout approach.
Slice the rest of the onion and pickle it. Try your salads with pickled onions instead of raw red onions. Try your other foods with the pickled onions. Salty foods tend to go well with acidic foods.
Pickling is an age-old technique used for preserving foods that still exists to this day because it adds novelty to foods. Anything pickled should last for at least a month more than its normal shelf life.
