Recyclable, reusable, and visually appealing packaging cushion made from recycled corrugated cardboard that overcomes the limitations of traditional packaging materials like air cushions and styrofoam. The packaging cushion is created by compactly rolling and compressing used corrugated cardboard boxes into a dense, high-density roll. This roll is then cut into thin, flat sheets that are stacked and compressed into a compact cushion shape. The resulting cushion provides excellent shock absorption and filling properties without the issues of leakage, puncture, static electricity, or contamination associated with air cushions and styrofoam. It also has a clean, uniform appearance compared to shredded cardboard. The compact cushion shape allows efficient storage and transportation of the cushion between shippers and recipients. The cushion can then be recycled or reused by compacting it back into a roll.

A food-grade barrier coating for molded pulp products like bowls, trays, and containers that provides water and grease resistance. The coating is made by crosslinking shellac resin applied to the pulp. The crosslinking involves thermal aging in an oven to melt and fuse the shellac chains. This creates a durable, water-repellent coating that penetrates the pulp fibers. The coated pulp products have low cobb (water absorption) and kit (grease penetration) values, making them suitable for food packaging. The crosslinked shellac barrier meets food migration limits at elevated temperatures.
