is there such a thing as defective vinyl? in Vinyl Posted September 28, 2014 I am in the middle of a shirt order and the vinyl doesn't want to peel away from the plastic. I've never had this happen before. I have tried increasing the temperature and time but it doesn't seem to matter. The only way I can get it to release is by pressing very hard with the weeding tools and carefully peeling away. I am using the Siser EasyWeed in white.
