Edge board, also known as corner board or angle board, is a packaging material used to protect the edges and corners of items during shipping and handling. It is typically made from multiple layers of paperboard or cardboard that are glued together to form a rigid, L-shaped profile.

Edge board is used to reinforce the edges and corners of boxes, crates, or other shipping containers, helping to prevent damage from impact, compression, or other types of stress. It can also be used to separate and stabilize layers of items within a package, reducing the risk of shifting and damage.

Edge board comes in a variety of sizes and thicknesses, and can be customized to fit the specific needs of the item being shipped. It can be cut to length and applied using tape, staples, or other fasteners, making it a versatile and easy-to-use packaging material.

One of the advantages of edge board is that it is a cost-effective way to protect items during shipping and handling, reducing the need for expensive cushioning materials or oversized packaging. It is also a sustainable choice, as it can be made from recycled materials and is recyclable itself.
