A release liner is to be made available which has a sufficient separating action on both sides, especially compared to PSAs with good adhesive strength, even on low-energy substrates. This is achieved with a release liner that - An external, continuous silicone release layer (SR1); - a film (BF) containing at least 80% by weight, based on the total weight of the film, of a polyolefin or polyethylene terephthalate; - a layer (PER) containing at least 80% by weight, based on the total weight of the layer (PER), of polyethylene; and - Includes an outer silicone release layer (SR2) lying on the layer (PER); the layer (SR2) having defects such that 46 to 95% of the surface of the layer (PER) is covered with the layer (SR2). The invention also relates to a method for producing such a release liner and its use for covering a synthetic rubber-based pressure-sensitive adhesive, the pressure-sensitive adhesive resting on the silicone release layer (SR1). |
