No they are different. Puff pastry has fat between layers, resulting in the puffiness or flakiness when baked. You'll want that for pies, NOT popiah skins.

Puff pastry is not hard to make...U can google for recipes. Remember to not let the butter/whatever shortening you use in the dough to melt....chill the dough in fridge between folding and rolling sessions. The more layers , the puffier yr pastry.
