A manufacturing apparatus of an environmental paper protective bag includes a planar structure manufacturing device including an inner layer unreeling module, an outer layer unreeling module and an inner-core layer unreeling module for unreeling multi-layer paper material, the unreeled multi-layer paper material superimposed, and arranged on a working platform to be transmitted along a conveying direction thereof; a tension adjusting device configured to adjust tension of the multi-layer paper material, a stretching module configured to stretch paper that has been die-cut into a network three-dimensional structure, a plurality of first gluing modules configured to glue bonding positions of the multi-layer paper material to join the multi-layer paper material together, a first press-fit module configured to press the bonding positions of glued multi-layer paper material to form a planar structure, which can solve a technical problem that conventional production equipments can't produce a protective bag with an inner-core layer.

A packaging material including one or more expandable layers that provide protection to contents of a packaging enclosure formed with the packaging material. The packaging material includes at least a first layer and a second layer bonded to one another. The first layer is pulled or extended in a first direction that is effective to cause the second layer to expand in a second direction. The second layer is a cut-patterned layer which creates structural strength in the packaging material when expanded.

A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

A cushioning packaging material for packaging one or more electronic products and the like is disclosed. The cushioning packaging material includes a cushioning portion provided with a plurality of air pockets, an air distribution portion provided with a distribution passage through which air is distributed into the plurality of air pockets, and an air inlet provided at one side of the air distribution portion. The air inlet is closed after completion of air injection. Thus, air leakage through the air inlet is prevented and cushioning force reduction caused by air leakage is also prevented.

A package having a flexible inner sheet having a first surface and a second surface. The package has an article reservoir for accepting an article to be shipped. The expansion chambers can be inflated or otherwise expanded to provide structure to the package and to protect the article in the article reservoir. The package also includes an external wrap surrounding at least a portion of the package to provide a relatively planar outwardly-facing surface.

An inflation feature for a shipping package, an inflation rig assembly for inflating a shipping package, and a method of inflating a shipping package. The method includes providing an inflation feature and an inflation rig assembly with corresponding alignment features, positioning the inflation feature of a shipping package, in an uninflated state, on to the inflation rig assembly in a first position, moving the inflation rig assembly to a second position, such that the shipping package is in fluid communication with an expansion material source, and inflating the shipping package to an inflated state.
