A closure arrangement for a polymeric bag has a pair of opposing films joined at a fold line and perforated along the fold line. The arrangement includes a base strip, a pair of heat-resistant strips, and a peelable strip composed of peelable material. The base strip has opposing inner and outer surfaces, and the outer surface of the base strip is securably arranged with respect to one of the pair of opposing films of the polymeric bag. The pair of heat-resistant strips are securably arranged to the inner surface of the base strip, and are spaced from each other so as to form a gap therebetween. The peelable strip includes a first 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 arranged with respect to the inner surface of the base strip. Various other closure arrangements are also disclosed.
