Absorbent fluff and tissue laminate pads for food packaging

An absorbent pad comprising:

• a first, outer layer comprising a permeable or non-permeable material;
• a second, outer layer comprising a permeable or non-permeable material, placed on a side of the pad opposite the first layer;
• and
• a third layer and a fourth layer disposed between the first layer and the second layer, the third layer being joined to the fourth layer, configured to serve as a substrate for the fourth layer and being in fluid communication with the fourth layer,
• wherein at least one chemical agent or system is fixed in the third layer or the fourth layer and has a functionality of carbon dioxide generation, super absorption, ethylene scavenging or inhibiting, oxygen scavenging, odor-removing, color- or taste-removing or changing, or antimicrobial properties, wherein the at least one chemical agent or system is distributed substantially uniformly in the third layer or the fourth layer and is activated by contact with a fluid.

A method of manufacturing an absorbent pad comprising:

• feeding a substrate layer and a web into a nip to compress the substrate layer and the web to form a mechanically bonded substrate layer and web, the substrate layer in fluid communication with the web and comprising at least one chemical agent or system fixed and distributed substantially uniformly in the substrate layer and being activated by contact with a fluid;
• applying a first, outer layer to a first side of the bonded substrate layer and web, the first layer comprising a permeable or non-permeable material;
• and
• applying a second, outer layer to a second side of the bonded substrate layer and web opposite the first side, the second layer comprising a permeable or non-permeable material.
