An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

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 shipping container, particularly suited for shipping wine bottles within a shipping box, having a pair of container halves. Each container half includes an outer tray that is shaped to fit the shipping box, and an inner tray that is configured for securely holding one or more wine bottles. Both the outer tray and inner tray are made of readily recyclable pulp material, and have a void therebetween. A starch based biodegradable insulation material fills the void therebetween, such that the shipping container is made entirely of biodegradable material, yet is sturdy and has insulative properties.

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.

In accordance with a broad embodiment of the invention, a novel paper product is comprised of two or more slit sheet packing material layers, each layer having its own slit pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. Adjacent layers have differing slit patterns and can be expanded through expander type machinery such that the expansion rates of the differing slit pattern layers can be varied to deliver the same width of exiting expanded material from each layer. Preferably the differing slit pattern produce when expanded, inclined land areas that have the same number of rows per inch, but different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

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.

According to some illustrative embodiments, a protective product is provided that includes: an envelope having a two-layer wall structure, the two-layer wall structure including a) a first outer paper layer, and b) a second inner paper layer, wherein the second inner paper layer includes width-wise positional variations of the side surface of the second inner sheet that cushions items placed within an inner pouch of the envelope, and forms an interior wall of the inner pouch of the envelope and directly contacts the items placed within the inner pouch of the envelope. In some preferred implementations, the width-wise positional variations of the side surface of the second inner paper layer includes pleats, undulations and/or embossments, and, preferably, the pleats, undulations and/or embossments include ridges that extend perpendicular or substantially perpendicular to an outlet of the envelope.
