A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

A packaging insert comprising a combination of corrugated cardboard and honeycomb paperboard, and packaging assemblies and methods of packaging an item utilizing one or more such packaging insert(s), as shown and described.

A full recycling environmental protection packaging structure applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A method for embossing optically diffracting microstructures in a thin foil, such as used to pack at least one of the list comprising food, chocolate, chewing gum, gifts, jewellery, clothes, tobacco products, pharmaceutical products, the embossing being produced with an embossing rollers set-up comprising at least one cylindrical embossing roller and a cambered counter roller. The method comprises confining the at least one cylindrical embossing roller and the cambered counter roller in a single roller stand of relatively small outer dimensions designed to withstand a pressure for the at least one cylindrical embossing roller and the cambered counter roller; using on a surface of a first one of the at least one cylindrical embossing rollers at least one raised embossing element adapted for microstructure embossing, whereby one of the at least one raised embossing elements comprises a platform distant at a height in a range between 5 m and 30 m above a surrounding surface of the first cylindrical embossing roller adjacent to it, and a pattern engraved on top of the platform (5), whereby the pattern comprises the optically diffracting microstructures with periodicity of gratings in the range smaller than 30 m that produce from a diffuse or directed source of light in the visible wavelength range diffraction images with high contrast and high luminosity in a defined observation angle; and adjusting the pressure for the at least one cylindrical embossing roller on the thin foil in a range less than 80 bar relative to a platform area of approximately 100 mm.sup.2.

A full recycling environmental protection packaging structure and a manufacturing method thereof applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the first surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure formed by paper material being stretched after being die-cut. The planar structure is sealed edges thereof and an opening is reserved to form a bag body. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A manufacturing method of a full recycling environmental protection packaging structure having a paper planar structure includes step S1, preparing at least two rolls of base paper rolls; step S2, selecting at least one roll of base paper roll, performing unreeling processing on the at least one roll of base paper roll to form a die-cutting paper, rewinding the die-cutting paper to be reserved; step S3, selecting at least one roll of base paper roll and at least one roll of die-cutting paper roll, synthetically unreeling the at least one roll of base paper roll and die-cutting paper roll along a same direction, stretching a die-cutting paper coiled material to form a liner belt, adhering the liner belt and an unreeled base paper reel belt to form a planar structure belt; step S4, sealing the planar structure on edges thereof so as to form a bag body having an opening.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

An expandable shipping container may be selectively expandable from a collapsed configuration to an expanded configuration by applying pressure to the sides of the container. The shipping container may include an inner structure having mirroring halves, each having a central rectangular face panel with bendable rectangular top, left, right, and bottom partial face panels extending from its sides and a square-shape corner panel positioned between each pair of partial face panels. The expandable shipping container may also include a flexible barrier covering an exterior of the inner structure and forming seams between one or more pairs of partial face panels of each half of the inner structure. The corner panels and left and right partial face panels of each half may include diagonal scorelines that, in conjunction with other scorelines, allow the container to be folded in a manner that facilitates convenient expansion.

A packaging cushion includes a first liner and a second liner opposite one another and each defining an inner surface. A transverse liner axis extends normal to the inner surfaces. The packaging cushion includes a mesh bonded to and disposed between the first and second liners. The mesh has a top mesh surface and an opposed bottom mesh surface. The mesh defines a plurality of nodes and a plurality of legs interconnecting the plurality of nodes. Each of the plurality of nodes defines 1) a top node surface defined by the top mesh surface, 2) a bottom node surface defined by the bottom mesh surface, and 3) a transverse node axis extending substantially normal to the top and bottom node surfaces. The transverse node axes of at least some of the plurality of nodes are each oriented at an oblique angle relative to the transverse liner axis.
