Ultra-Clear BOPP (on Clear liner – Permanent Adhesive) – This is the same material as the one above, but it comes on a clear PET liner. This liner is usually best for high-speed automatic applicators, but one additional benefit is that the finished labels can appear a little less hazy due to the way the adhesive reacts with the liner. It’s important that you confirm with your label applicator that their equipment can handle clear-on-clear labels, as there can be unusual challenges in detecting the gaps between labels.
