Abstract
Provided are adhesive articles that include a barrier layer that is substantially impermeable to oxygen gas at ambient temperature and pressure along with a heat-bondable layer, which could be a discrete layer adjacent to the barrier layer or integral with the barrier layer. The adhesive article further includes a backing extending across and coupled to the barrier layer and an adhesive layer extending across and coupled to the backing opposite the barrier layer. The barrier layer reduces or eliminates migration of plasticizers from the bonded seal into the adhesive article, limiting deterioration of tape performance over time.
