Use fully heated iron. You can also use thin cloth between document and iron if it's ur first time.1. Cut out the extra plastic on side 2. place iron on edge and let it stay until it slightly burns the plastic forming a bubble like between plastic n paper. Do it again n again if u don't get bubble by placing iron the first time ( keep placing iron on document until u get the bubble/ popped up plastic).3. Then insert the blade to make a cut only in the popped up plastic be careful not to cut the document itself.4. Iron around the cut n then start pleeling plastic my inserting ur nail/blade into the cut u had already made, do it very slowly n gently so the document does not get damaged.5. Keep ironing and pleeling until all don't on one side then turn document overleaf n repeat same process for the other side, don't mind if the previous side sticks on to the table. In the end cover ur document ( that has sticked to table) with cloth and iron well this will make it stick back to cloth....again by the help of ur nail pull document off the table easily.....separate it from the cloth. Documents with colored background are tougher to delaminate as any small mistake will leave a white patch that can be easily seen on the colored background. Quick tip- if by mistake u peeled off a bit of paper while pulling plastic off stop immediately iron to stick it back again then pull plastic n stop exactly till where u have peeled before insert blade beyond the peeled and slowly cut off the connection between the peeling paper ( that is a small patch that will still peel if you pull )n plastic this will eliminate any further damage to ur document........it took me around 1 hour for one document so have patience. sorry for short video I was in a rush otherwise I would have recorded it till the end.......don't forget to like my video if you find the info useful and that its my first video that I had uploaded ever on net :$
