Technical Tips

Optimizing OPP

• Use OPP films within three to six months of receiving them to avoid additive migration and fading of surface treatment.

• To prevent shrinkage and reduced wetting tension, store both free film and laminated and/or printed shrink OPP films at temperatures less than 90°F, even for short periods of time.
