Yes, you would suffocate due to the bag restricting your airway.
You breath up all the oxygen inside and then you will die due to no oxygen in your lungs.
If you are planning to kill yourself by putting a plastic bag over your head, there are probably other questions that you should be asking, rather than how long it takes to die with a plastic bag over your head. The problems that you find impossible to solve, which therefore make it necessary for you to kill yourself, may have solutions. It would at least be worth asking about it. Sometimes our answers are really helpful. Anyway, as with many of the questions on this site, the answer is not as simple as you may think. Not all plastic bags are of the same size, and even then, the same size bag may not contain the same amount of oxygen, because that depends upon how tightly you have fit it over your head, whether you had inhaled or exhaled before putting it over your head, and details of that sort. So the time varies. As an approximate rule of thumb, it's about 15 minutes. Also note, your head may get very hot, since the plastic bag defeats the normal evaporation process of perspiration, and the whole process can become very uncomfortable. Suicide is seldom painless.
You can put them over your head and die :P
The bag blocks any air from accessing your windpipe if it is wrapped around your head or placed over your mouth. It is a slow death. If you are suffocated by a bag, you have more chance of slipping into a coma than dying due to oxygen starvation of the brain - but you can still die from it.
