The utility model provides a rectangular-ambulatory-plane narrow-edge VHB foam layer structure. The rectangular-ambulatory-plane narrow-edge VHB foam layer structure comprises upper release paper, VHBfoam, inner frame release paper and PET low-viscosity films. Wherein the VHB foam is single-sided adhesive foam, the upper part of the VHB foam is provided with adhesive, the upper release paper andthe VHB foam are homocentric-squares-shaped, the upper release paper is adhered above the VHB foam, the inner frame release paper and the PET low-viscosity film are rectangular, the inner frame release paper is adhered to the inner side of a homocentric-squares-shaped opening of the homocentric-squares-shaped VHB foam, and the PET low-viscosity film is adhered below the inner frame release paper.And a notch broken knife line is formed in the rectangular-ambulatory-plane width direction of the upper layer release paper and serves as the position of a tearing hand. A layer of PET low-viscosityfilm and inner frame release
