The invention provides a recyclable polyolefin skin-touch film as well as a preparation method and application thereof, and relates to the technical field of skin-touch films. A recoverable polyolefin skin feeling film comprises an outer layer, a core layer and an inner layer, and the thickness ratio of the outer layer to the core layer to the inner layer is (10-20): (60-80): (10-20). Each of the inner layer and the outer layer comprises the following raw materials in parts by weight: 2-15 parts of isotatic polypropylene, 2-15 parts of high-density polyethylene, 8-20 parts of block polyolefin and 0.5-2 parts of an anti-blocking agent. The ABA type polyolefin skin-touch film prepared through a tape casting process can be recycled and used for self-production or production of other polyolefin products, the products conform to the national dual-carbon development strategy, and the prepared polyolefin skin-touch film has excellent mechanical strength.
