Im trying to cut some plastic coated MDF (Melamine?) using a powered jig

A friend told me there is a special blade for doing this. Can anyone advise
me?
Im a rank amateur with only a jig saw and a planer to my my name.. I
dont want to buy any further power tools as Id not have any real use

I would say the finer the teeth the better and use something to cover the Melamine stuff like a strong tape or even a metal ruler to protect and help stop any Melamine rising and hence breaking off.
