EcoQuality classic pads are our traditional product, consisting of a cellulose core surrounded by poly film and sealed on all four edges. They are mainly used for meat and fish, showing absorbencies of up to 75 grams with our standard sizes. The cellulose core in Classic pads resembles a sponge in its ability to absorb liquids, and the perforated poly film allows for the liquid to easily enter the pad while limiting its ability to exit. Classic pads are our most basic and commonly used pads and are normally thicker than our other products due to their fluffed core. Features. White absorbent pads. Patented sealed-edge technology. One-way valve. Virgin fluff pulp core. Superior absorbency.
