For our thermal roll labels, we offer standard white with a permanent adhesive, removable white with a low tack temporary adhesive, and a white weatherproof with a permanent adhesive. At this time we do not carry a blockout material for thermal rolls but do offer this on our 8.5" x 11" sheeted labels. I have included a link below for your review. https://www.onlinelabels.com/material_blockout_laser_labels.htm If you'd like to try samples of any of these materials, you are welcome to visit the link below to request samples at no cost. https://www.onlinelabels.com/samples You can also request custom sizes and configurations at the following link or contact Customer Support at 888-575-2235. https://www.onlinelabels.com/special-order-custom-size-labels.aspx
