A shipping assembly is described. The assembly includes a shipping container, a bottom structure, and a top structure. The bottom and top structures retain objects in a spaced-apart arrangement within the shipping container. A paperboard sheet is folded into three horizontal layers to form the bottom structure. A first layer has apertures to retain the objects. A second layer is below and spaced apart from the first layer with a substantially flat surface below the first apertures. A third layer is below and spaced apart from the second layer. Another paperboard sheet is folded into two horizontal layers to form the top structure. A fourth layer has another set of apertures to retain the objects. A fifth layer is above and spaced apart from the fourth layer. The apertures are align to position the objects in the shipping container.

A washing machine tub lock device is provided that prevents the wash tub from impacting the washing machine cabinet during shipping and handling. The tub lock device is formed by cutting and folding a corrugated blank into an inverted truncated rectangular cone that can be wedged inside the top portion of the washing machine tub. The tub lock device includes hanging tabs which prevent the tub lock device from falling into the wash tub during shipping and handling. The tub lock device also includes elliptical tabs which bend or deform into elliptical cutouts such that the edges of the elliptical cutouts are covered, thus preventing the elliptical cutouts from damaging the washing machine during shipping and handling.

Provided is a cushioning material obtained by stacking a plurality of cushioning sheets, in which the plurality of cushioning sheets include a first cushioning sheet, a second cushioning sheet having a strength stronger than that of the first cushioning sheet, and a third cushioning sheet having a strength stronger than that of the second cushioning sheet.

A cushioning material having a multilayer structure includes: a first layer whose strength in a first direction in which the cushioning material extends is stronger than a strength in a second direction that is a direction in which the cushioning material extends and is opposite to the first direction; and a second layer whose strength in the second direction is stronger than a strength in the first direction.

A cushioning sheet includes a first portion provided in a first area, and a second portion provided in a second area and having a strength stronger than that of the first portion.

A molded packing material and a method of making the molded packing material. The molded packing material includes a plurality of molded fiber cushioning elements. The molded packing may also include a matrix comprising cellulosic fibers bonding the plurality of molded fiber cushioning elements to each other. The plurality of molded fiber cushioning elements and matrix form a mass that has been molded into a shape having exterior surfaces and an interior with some of the plurality of molded fiber cushioning elements being on the exterior surfaces of the mass and the remainder of the plurality of molded fiber cushioning elements being in the interior of the mass. The molded packing material may also include a fiber shell having a cavity formed therein with the plurality of molded fiber cushioning elements located in the cavity.

This invention is related to a 2-ply corrugated paper-based envelope with crease lines and glue strips for primary and secondary packaging and transportation needs. The envelope comes with glue strips in single or double (for reverse logistics if required) lines. These envelopes can be enhanced with a provision for tear tape for the frustration-free opening of the package. To enhance evidence of tampering of the envelope, there is an option for perforation. The envelope can come with a numbering system all around except at the top, where tear tape can be provided for ease of opening. To help in identifying if the package has been tampered with, there is an option of printing a line along with the flap/opening with special ink which turns pink in color when comes in contact with heat.

A paperboard protective corner and a method for manufacturing a paperboard protective corner, the paperboard protective corner comprising: a corner body made of a single paperboard sheet comprising first and second side edges, the single paperboard sheet being folded onto itself to form the paperboard protective corner, the single paperboard sheet including a plurality of folds, both the first and second side edges being received in a corresponding fold so as to be unexposed to an exterior of the paperboard protective corner.

A protective packaging product comprises a plurality of stacked layers, at least some layers preferably comprising a foamed material, and at least some layers being adhered to an adjacent layer. The inventions proposes that at least some layers are made of a polysaccharide material, and that adjacent polysaccharide layers are adhered to each other by means of a polysaccharide bonding material.

Provided is a packaging envelope insertion-type paper buffer safety member which can be inserted into a packaging envelope in order to cushion impacts. The paper buffer safety member includes a base member made of rectangular paper having a certain thickness; and a paper buffer material attached to the rear surface of the base member. A plurality of width direction fold lines are formed on the front surface of the base member so as to be spaced a certain distance from each other. On the front surface of the base member, a first adhesive layer is formed over the entire lower end in the longitudinal direction, and a second adhesive layer is formed over the entire upper end other than a portion of the front side.
