A system and method for an easy-to-open liner for use in connection with soil and sediment samplers, including direct push technology, rotary and coring systems, is disclosed. The liner is pre-scored along its length by one or more score lines formed in the exterior surface or the interior surface of the liner. After removal from the sampler, the liner can easily be opened to expose the contained sample without the need of cutting blades or other sharp objects, in accordance with health and safety requirements.
