A method of preparing a packaging laminate includes conveying a mesh of paper material having perforations against a rigid edge causing, at substantially each perforation, a mesh portion at the leading side to have an average elevation lower than that of a mesh portion on the trailing side of the perforation. The method includes expanding the perforations into cells separated from one another by legs interconnected by nodes defined in the mesh Top and bottom surfaces of the legs and nodes are reoriented from an initial orientation substantially parallel with a direction of conveyance of the mesh to an expanded orientation oblique to the direction of conveyance, such that, in the expanded orientation, the top surfaces of the nodes are substantially parallel with each other. The method includes attaching an outer liner to at least some of the bottom surfaces so as to form the packaging laminate.

An inflation bag with protective base is provided. Two outer films and two inner films are stacked with each other, and the stacked structure is heat sealed and inflated to form the inflation bag. The inflation bag includes two side surface walls and a bottom surface wall between the side surface walls and connected to bottoms of the side surface walls. The bottom surface wall includes bottom columns. Each bottom column has a first bottom column portion, a protection column portion, and a second column portion. A first heat-seal node is provided for attaching the outer films with the inner films, and the first bottom column portion is connected to the second bottom column portion. One or more second heat-seal nodes are provided on the protection column portion for attaching the outer films with the inner films, and the protection column portions are folded to form a protective base.

A packaging bag for shockproof includes a bottom wall, a shielding portion, a limiting film and a cover body. Both sides of the shielding portion are adhered to the surface of the bottom wall by heat sealing, and a nesting space is formed between the shielding portion and the bottom wall. The limiting film is stacked above the bottom wall and includes a body and a reversed portion. An accommodation space is formed between a bottom surface of the body, the surface of the bottom wall and the outer longitudinal heat sealing lines, and a limiting space is formed between the top surface of the body, an inner side of the reversed portion and the inner longitudinal heat sealing line. The cover body includes cover air columns located on an upper side of the bottom wall.

A cushion structure and a package box are provided, which relate to the technical field of a protection pad. The cushion structure comprises a cushion pad which includes a multi-layered folding structure and a plurality of folding layers. One end of one folding layer is connected to one head of another folding layer neighboring to the one of the folding layers, and the folding layers are disposed in an overlapped manner after being folded. An accommodating space is formed between neighboring two of the folding layers, and the accommodating space is configured to accommodate an object. A through hole is disposed on the folding layer to prevent the object from sticking with the folding layer. A reserved pad protrudes from an edge of each folding layer, and two surfaces of the reserved pad are respectively coplanar with two surfaces of the each folding layer.
