 It is common among imported materials that are heavily processed with low-quality dyes, to experience dye migration. This happens when the polyester garment dyes “bleed” into the polymeric heat transfer applications after normal use. ThermoFlex Subliblock vinyl has a specially formulated layer, that will literally block this dye migration, preserving your beautiful HTV designs! Subliblock film is soft hand, flexible, long-lasting, and has a low-temperature adhesive to prevent press marks! It is thin yet durable, and very pliable to apply to garments. As with our other ThermoFlex vinyl, Subliblock has a pressure-sensitive carrier, to allow easy weeding and repositioning.
