Package having a flexible inner sheet, a flexible secondary inner sheet, a flexible secondary outer sheet, and an outer sheet. The inner sheet and secondary inner sheet are joined together at least an outer seam and forming one or more primary expansion chambers. The package also has a flexible secondary outer sheet and an outer sheet, joined together at least an outer seam and forming one or more secondary expansion chambers. The secondary outer sheet and the outer sheet also form one or more non-expansion chambers that can be a label surface.

A package body includes a porous metal body having an elongated sheet shape, a core member having a cylindrical shape, a protective sheet, and a resin film. The porous metal body is wound around the core member. The protective sheet is wound around the wound porous metal body to cover an outer surface of the wound porous metal body. The protective sheet and the porous metal body are covered with the resin film. The core member is made of paper or a resin.

The present invention discloses a method of producing at least a pair of interlocking adjacent layers of a paper packaging product, the pair of interlocking adjacent layers being formed of a sheet of slit paper having a slit pattern, the slit pattern upon expansion, forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet. The method comprises slitting the sheet of slit paper with beveled blades that have a first wedge angle on one side of the blades and a second wedge angle on the other side of the blades, wherein the first wedge angle is wider than the second wedge angle to produce slits that upon expansion, produce the lands regions that have angles of inclination in a range for 50 to 85 degrees.

A protective packaging web is disclosed. The web includes a flexible inflatable web that includes inflatable chambers having inlets and configured for receiving a fluid from the inlets and sealing the fluid therein, the inflatable chambers being configured such that, when inflated, the inflatable web structure has a first contoured exterior surface including a plurality of peaks and valleys, and a flexible first outer ply affixed to the peaks and detached from the valleys of the first contoured surface, such that when the inflatable chambers are inflated, the first outer ply extends along a phantom first tangential surface, bridging the valleys of the first contoured surface, such that when the chambers are inflated the affixed first outer ply and the inflatable web cooperatively form a framed structure having significantly elevated bending stiffness compared to a bending stiffness resulting from the inflatable web structure absent the attached first outer ply.

An adhesive wrapping system is provided. The adhesive wrapping system has a flexible sheet of material which has a planar layer and an opposing padding layer. The padding layer comprises a plurality of concave recessions, which when mated with the planar layer, forms gas-filled bubbles that provide a cushioning surface. The sheet of material further comprises a plurality of perforations which are linearly disposed across the sheet to provide a user with the ability to select a size and shape of material to be used. An adhesive is also disposed along at least one length of the sheet of material which secures the material to a desired surface, such as the sheet of material itself. A removable adhesive covering is disposed over the adhesive to preserve the adhesive until the adhesive is exposed for use.

A filling bag with good thermal insulation and anti-collision performance and a manufacturing method thereof. The filling bag includes a sealed bag body and a filling tube head, and the sealed bag body includes a substrate layer and at least one thin film layer. At least one side of the substrate layer is provided with a mesh adhesive layer, and the thin film layer is compounded with the substrate layer through the mesh adhesive layer, so that a plurality of bubble cavities are formed between the substrate layer and the thin film layer. The bubble cavities are filled with gas. The thin film layer is compounded on the side of the sealed bag body to form a layer with dense bubble cavities filled with gas, a gas insulation interlayer is formed on the side of the sealed bag body, which has good thermal insulation effect.

The invention relates to an envelope-type flexible shipping pouch having an inner pouch defining a compartment for receiving an item, an outer pouch incorporating the inner pouch, an opening for accessing the compartment, and a system for closing the opening. The system for closing the opening includes first adhesive means that ensure said opening is kept closed. The inner pouch and the outer pouch are secured together so as to define an inflatable chamber around said inner pouch. The pouch includes a channel extending into the chamber, the channel including an outlet opening into the chamber and an inlet opening onto the pouch, where the placement of the system for closing the opening simultaneously leads to the sealing of said channel.
