The invention relates to a machine direction oriented plastic film as a release liner for a pressure-sensitive label, wherein the plastic film comprises a polypropylene homopolymer and a hydrocarbon resin. The invention also relates to a method for producing a release liner for pressure-sensitive label. In the method at least one polypropylene homopolymer is selected as one component and at least one hydrocarbon resin is selected as another component. A relative amount of the at least one hydrocarbon resin in a mixture of the at least one polypropylene and at least one hydrocarbon resin is selected, the at least one polypropylene homopolymer component and the at least one hydrocarbon resin component are mixed in said relative amount by melt processing to form a monolayer or multilayer plastic film. Said plastic film is oriented in a machine direction; and the machine-direction oriented plastic film is coated with a releasing agent to form a release liner. |
