An absorbent pad for meat and poultry products and the like and a method for constructing same is disclosed. The absorbent pad includes upper and lower plastic film layers, at least one of which is perforated, and an intermediate absorbent layer disposed between the layers. The intermediate absorbent layer includes a series of juxtaposed and overlapping absorbent material fibers with superabsorbent granules dispersed throughout the absorbent layer and supported by the absorbent material fibers within interstices thereof. The superabsorbent granules are capable of absorbing and suspending liquids therein while being physically retained in place and supported by absorbent material fibers of one or several types, even when the absorbent material fibers have liquid therein. The superabsorbent granules are fixed and held in place by structurally interacting absorbent material fibers and/or by attachment to one or more of the types of absorbent material fibers constituting the absorbent layer. The upper and lower film layers are attached to one another at least partially along opposite marginal edge portions thereof to retain the absorbent layer between the upper and lower layers. The superabsorbent granular particles are homogeneously dispersed throughout the absorbent layer and supported in generally spaced relationship within the interstices of the absorbent material fibers, to enable suspension and retention of liquid by said superabsorbent granules and absorbent material fibers.
