I Have Printed Onto Card Some Playing Cards Of My Own Design And Now Want To Protect Them By Laminating Them?

If I laminate the A4 sheet that they are on and then cut the cards out will the laminate still stay on the cards or just peel away. I know you can buy credit card size laminating pouches, but if i buy these will they work on a laminator that accepts A4 pouches? I dont own a laminator yet and dont want to buy one if this idea wont work
