The present disclosure relates to crush resistant packaging materials and/or constructions and to methods of making and using them. Many embodiments provide crush resistance in addition to customizability.

Disclosed are multilayer films with high toughness performance, where the films have an elastic ethylene copolymer in the core layer.

A packaging laminate includes a core layer having at least one through-hole which on one side is covered by a barrier film and an outer layer of a polymeric material, wherein said outer polymeric layer and said barrier film are laminated to each other in a manner such that said polymeric layer and said barrier film are separated from each other along parallel, visually detectable air-filled channels formed by these two layers within the area of said at least one through-hole.

This disclosure relates to ethylene interpolymer compositions, films prepared therefrom and a nonlinear rheology method capable of determining presence of long-chain branched structures in these ethylene interpolymer compositions. Ethylene interpolymer compositions disclosed herein specifically relates to ethylene interpolymer products having: a dimensionless nonlinear rheology network parameter, ?.sub.int., greater than or equal to 0.01, satisfying 0.01?(Z?48).sup.0.78??.sub.int?0.01?(Z?60).sup.0.78 inequality wherein Z is a normalized molecular weight defined by (I) where Mw and Me are the weight average and entanglement molecular weights; and a residual catalytic metal of from ?0.03 to ?5 ppm of hafnium. The disclosed ethylene interpolymer products have a melt index from about 0.3 to about 500 dg/minute, a density from about 0.855 to about 0.975 g/cc, a polydispersity, M.sub.w/M.sub.n, from about 1.7 to about 25 and a Composition Distribution Breadth Index (CDBI.sub.50) from about 1% to about 98%.

A paper based cellulosic dunnage for use during transportation of goods. The dunnage may include an inner core, with a plurality of vertically aligned cellulosic cells that may be hexagonal in shape. The dunnage may include a top linerboard, attached to the top surface of the inner core, and corner boards, attached to the top and side surfaces of the inner core.

A laminating roller for laminating a sheet of a packaging laminate comprises at least one groove extending along the periphery of the roller and forming a border between two circumferential portions, wherein each of the two circumferential portions are extending continuously around the surface area of the roller. The laminating roller can also be used in a method for providing a packaging laminate.

A web, method, and apparatus for forming dunnage units. The web includes first and second elongated layers. A plurality of seals that hermetically join the first elongated layer to the second elongated layer to form a plurality of inflatable pouches and an inflation channel that is in fluid communication with pouches and is disposed outside of the pouches. An inflation side line of perforations, a gap forming area, and an opposite side line of perforations are arranged in a line between pair(s) of the pouches.
