Steve - do you need a primer still?What version of the bags are they?If standard Polypropylene bags, any of the many low cure inks on the market will work fine.
They will never be washed so cure is not a issue.

I put nylonbond in my inks.

We do have some for jackets of course, so I will have to check it out if other folks have it working for them. Thanks all.Steve

I have IR dryer, no air with 6' of heat. I just zip them through the dryer so they are dry to the touch and they are not melted. The ink should be very hard after 2 days. No problems at all.PeterPerhaps the Nylobond also helps on the adhesion on this material. No specific knowledge of that fact here, but it also can help lower temp curing if a heat based ink is used.
