Hi, I purchased 3 different types of bagging material from you a couple of years ago, now I can't identify what their specific application is cause your product codes have changed. What I have is VBF152 (blue), VBFEL (green), VBRF (green). Can you clarify?  I noticed the VBFEL is probably 'elastic', it however sticks firmly to the prepress after curing....Thanks for helping Alexander
