Packing members which are formed from expanded plastic foam sheet, such as polystrene, wherein the sheet is resilient. The sheet is provided with a backing which may be formed of bendable paper. A typical packing member will be formed by dividing the sheet into two legs by a longitudinal groove which is V-shaped in cross section and which does not extend into the backing. The surfaces of the foam sheet defining the V-groove are coated with an adhesive which will bond the legs together in annular relation at a later date so that the packing member may be shipped in its flat state. Because of the compression of the sheet material, it may be readily bent to form corners as opposed to cracking with the result that a leg of the packing member may be provided with a V-notch to divide that leg into two portions. The V-notch will be closed when the other leg is bent at right angles.
A packing member in the form of an edge or corner protector, said packing member comprising a plastic foam sheet having a sheet material backing, and said plastic foam sheet having a longitudinal V-groove dividing said plastic foam sheet into two legs connected to one another by a hinge defined by said sheet material backing, said V-groove in combination with said hinge defining means for facilitating folding of said two legs from a planar state to one wherein said two legs are generally at a right angle to one another with the foam of one leg abutting the foam of the other leg, surfaces of said V-groove having an adhesive coating which is a water soluble rubber latex thereon for forming a bond when said legs are folded to bring said surfaces of said V-groove into facing contact.
