In one embodiment, a closure arrangement for a polymeric bag having a pair of opposing films comprises a wide base strip, a pair of narrow heat-resistant strips composed of heat-resistant material, and a T-shaped peelable strip composed of peelable material. The base strip has opposing inner and outer surfaces, and the outer surface of the base strip is adapted for attachment to one of the pair of opposing films of the polymeric bag. The pair of heat-resistant strips are attached to the inner surface of the base strip, and are positioned generally parallel to each other and spaced from each other so as to form a gap therebetween. The peelable strip includes a top portion having opposing first and second surfaces and a stem portion extending perpendicular to the first surface of the top portion. The stem portion extends into the gap between the pair of heat-resistant strips and is attached to the inner surface of the base strip. The top portion is positioned generally parallel to the pair of heat-resistant strips with the first surface opposing the pair of heat-resistant strips. Various other closure arrangements are also disclosed.
