Various embodiments of the present disclosure provide an improved edge protector having two plies wrapped around a core and a method of manufacturing the improved edge protector.

A cushioning member includes: an accommodating bag portion that accommodates a medium; a first fusing portion that defines the accommodating bag portion such that the accommodating bag portion is provided with an opening; a check valve having a first end located inside the accommodating bag portion and a second end located outside the accommodating bag portion, and provided at the opening; a second fusing portion that is immediately adjacent to the first fusing portion on those external sides of the check valve which are opposite in a direction intersecting a direction in which the check valve protrudes from the accommodating bag portion, and defines a channel that communicates with the opening; and a third fusing portion that is connected to the second fusing portion and seals the channel, the third fusing portion being provided across a portion of the check valve that protrudes from the accommodating bag portion.

An inflatable airbag without a heat-resisting layer and its manufacturing method is provided, the inflatable airbag comprises two cavity films, wherein the boundaries of the two cavity films are glued together; the inflatable airbag further includes two valve films which are arranged between the two cavity films; first heat-seal lines are arranged at top ends of the valve films; the valve films and the adjacent cavity films are glued through the first heat-seal lines; the inflatable airbag further includes second heat-seal lines, wherein the second heat-seal lines include disconnected areas and heat-pressing areas which are arranged alternately; in the heat-pressing areas of the second heat-seal lines, the two valve films and two cavity films are glued together; an inflation channel is formed by portions of the two cavity films above the second heat-seal lines; a bag body is formed by portions of the two cavity films below the second heat-seal lines.

A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side crumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage. The entry and exit-side crumpling members are displaced laterally along the path with respect to each other to cause shearing of the sheet within the crumpling zone.

A 3D shaped product (20) is formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30% by weight of the air-laid blank. The 3D shaped product (20) is recyclable in a repulping process. At least a part of the thermoplastic polymer binder is water soluble at a repulping temperature of the repulping process. The 3D shaped product (20) are environmentally friendly alternatives to plastic 3D shaped products made by foamed polymers and can be recycled in existing recycling schemes.

A 3D shaped packaging product (20) for cushioning and/or thermal insulation of packaged goods is formed by hot pressing at an average pressure equal to or below 200 kPa of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30% by weight of the air-laid blank (10). The 3D shaped packaging product (20) has a density that is less than four times a density of the air-laid blank (10) and the density of the 3D shaped packaging product (20) is selected within an interval of from 15 to 240 kg/m.sup.3. The 3D shaped packaging product (20) maintains at least a significant portion of the porosity of the air-laid blank (10) even after hot pressing and therefore provides excellent shock absorbing and damping properties and thermal insulation.

An apparatus for the manual/automatic production of a tube-like packaging material can include a guiding chute with an opening for ejecting the packaging material from a roll arranged in the ejection position, wherein the guiding chute has an inner contour narrowing towards an opening in an ejection direction, a primary seating for at least partly circumferentially gripping the first roll and for holding the first roll in the ejection position, and at least one secondary seating for receiving of at least a second roll for reloading the apparatus, wherein the secondary seating is movable with a second roll between a passive position in which the second roll is outside an ejection position and an active position in which the second roll is arranged in the ejection position or is displaceable from the secondary seating into the primary seating under (e.g. exclusively under) the impact of gravity.

An expanded paperboard mesh, for supporting an item and separating such item from an adjacent object, includes a plurality of adjacent apertures, and each aperture entire perimeter is bounded by adjacent strands. The expanded paperboard mesh support is formed by expanding a single piece of paperboard to define said plurality of adjacent apertures. A combination includes an expanded paperboard mesh supporting an item over a supporting surface.

A food support tray comprised of an expanded paperboard mesh tray insert for a delivery carton such as a pizza carton or a fresh produce clamshell. The expanded paperboard mesh is adapted for supporting pizza or other food items on the bond peaks of the expanded mesh, thus isolating the food item from oil and juices that could make the fresh food item turn soggy.

Various embodiments of the present disclosure provide an improved edge protector having two plies wrapped around a core and a method of manufacturing the improved edge protector.
