Sealing member formed by a sealing film with a substantially longitudinal portion to be torn out, wherein the sealing film is connected to a pulling strip made of a layer, with fibers extending in a direction forming an angle between 60 and 60 with respect to the tearing direction of the longitudinal portion to be torn out. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.
