Temp and time for the gift bags is 180 for 60sec medium pressure, any longer than this the bag may turn yellow. Please test before you press as all flat presses will differ in heat. Cover with a sheet of copy paper and silicone paper (it helps with burning).
Tips:
Put 1mm MDF inside the bag on both sides in the groove then x4 layers of white felt in the middle, if you don’t you will have pressure issues when pressing. The felt and the MDF stops the impressions of the folds inside the bags from showing through the back.
