The present invention provides process for producing a ballistic-resistant molded article, which molded article comprises: i) a plurality of layers of unidirectionally aligned polyolefin fibers, which layers are substantially absent a bonding matrix; and ii) a plurality of layers of adhesive, and which process comprises: a) providing a plurality of precursor sheets, each of said precursor sheets comprising i) at least one layer of unidirectionally aligned polyolefin fibers which layer is substantially absent a bonding matrix, and ii) at least one layer of adhesive; b) stacking said precursor sheets to form a stack, wherein the total amount of adhesive in the stack is from 5.0 to 12.0 wt. % based on the total weight of the stack; c) pressing the stack produced in step b) at a temperature of from 1 to 30° C. below the melting point of the polyolefin fibers and at a pressure of at least 8 MPa; and d) cooling the pressed stack produced in step c) to at least 50° C. below the melting point of the polyolefin fibers while maintaining pressure.
