A box formed from a plastic corrugated material with soft score lines is provided. The soft score lines are formed to enable the top flaps of the box to lay substantially flat against the outer surface of the box when folded to an open position.

A corrugated fiberboard comprising cellulosic fibers, wherein said corrugated fiberboard has at least one of a geometrical tensile index in the range of from 32 to 65 Nm/g, a fracture toughness index in the range of from 4 to 24 Jm/kg, and a ring crush index in the range of from 5 to 10 Nm/g5 measured at relative humidity of 85% RH; wherein the cellulosic fibers comprises a mixture of less refined fibers having a Schopper-Riegler (SR) value in the range of 15 to 28 and microfibrillated cellulose fibers, wherein mixture comprises said microfibrillated cellulose in a range of from 1% to 5% by weight of the dry content of the cellulosic fibers.

Material for packaging—and package or receptacle made of such material—that contains a particular aluminized polymeric film with emissivity of equal to, or less than 0.10 and yet sufficiently thin to withstand and satisfy industrial requirements of the recycling process due to substantially complete oxidization of aluminum during the recycling. An optional protective coating (less than one micron in thickness) may be added to protect aluminum in the film from corrosion during the normal use of the packaging. Protective coating is configured to not raise emissivity of the aluminized surface above the 0.10 value and, at the same time, to still allow for the aluminum material it covers to be removed due to becoming fully oxidized and corroded in the heat and at humidity levels used in the recycling/repulping process. Proposed configuration permits the aluminum of the packaging material to be included in the recycled portion of the packaging material.

The invention relates to a ply of a linerboard for corrugated board, which ply exhibits high strength properties and which enables the production of lightweight linerboards. The ply of the invention comprises 20-80 wt % CTMP from wood fibers and 80-20 wt % chemical pulp, calculated on the total fiber weight of said ply and strength additives chosen from the group of microfibrillated cellulose (MFC), anionic or cationic polymers and starchor combinations thereof. The ply exhibits a geometric SCT index of above 22 Nm/g and a density of below 680 kg/m.sup.3, preferably of below 650 kg/m.sup.3.

A biodegradable additive is provided to enhance decomposition of a packaging material and/or to release nutrients into the soil as the packaging material decomposes. The biodegradable additive can be applied to a surface of the packaging material as a coating and/or as an adhesive to bond two or more layers of the packaging material together. The biodegradable additive includes an organic fertilizer having one or more nutrients such that the biodegradable additive can release the one or more nutrients when the packaging material decomposes.

A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

A compressible liner for a helmet or other apparatus subject to shock loading comprises three substantially co-extensive layers mutually engaged by respective cone-like protuberances and cone-like recesses. The intermediate layer is of a different compressibility and provides for de-coupling of the layers in an oblique impact.

One or more implementations of a multi-layer film include a first substantially un-pigmented layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first substantially un-pigmented layer non-continuously bonded is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

A method for producing a packaging material comprises providing a core material layer of fibre-based material having an inner side and an outer side, embossing the core material layer for forming embossed features having an initial height, the embossed features protruding from the outer side of the core material layer to later form a tactile pattern on a side of the package to be formed by the packaging material, and laminating at least one layer to the inner side of the embossed core material layer such that the height of the embossed features is temporarily reduced to a minimum height.

A repulpable moisture resistant protein box having a composite structure with a fluted medium, a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium. The backing boards are impregnated with a hydrogenated triglyceride on the wire side and the fluted medium is also impregnated with a hydrogenated triglyceride. The backing boards each have an outer felt side surface coated with styrene acrylic co-polymer. The protein boxes have a higher compression, moisture resistance and are recyclable.
