Barrier films comprising a PECVD barrier coating with diamond-like carbon are disclosed, along with methods of manufacturing such films, and laminated packaging materials comprising such films, in particular intended for liquid food packaging are disclosed. Packaging containers comprising the laminated packaging material or being made from the laminated packaging material, in particular to a packaging container intended for liquid food packaging are also disclosed.

A laminated packaging material for liquid food products comprising, a core layer of paper or paperboard or other cellulose-based material, a laminate portion being arranged on a first side of the core layer, a dark colored flexographic ink composition printed onto the free surface of the laminate portion, the dark colored ink composition comprises color bases mixed at a ratio such that a total energy absorption by the dark colored flexographic ink composition, when provided on the laminated packaging material, is below 80%, such as below 70% in an emission spectra from a tungsten light source in the region 250-2500 nm at a temperature of 3000 K, the dark colored flexographic ink composition has a color space lightness value L*≤25, and a color space difference equal to or lower than 6, with respect to a specified black reference composition.

The present invention relates to a laminated liquid food packaging material, comprising a bulk layer of paper or carton or other cellulose-based material and outer layers of thermoplastic polymers on both sides, having a decorative print pattern arranged beneath one of the outer thermoplastic polymer layers. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

The invention concerns a fibrous-based oxygen barrier film, which comprises (i) a microfibrillated cellulose (MFC) film, (ii) an oxygen barrier polymer layer, (iii) an optional tie layer, and (iv) an outermost polyolefin layer. The invention even concerns a laminate, in which said multilayer film is combined with a fibrous paper or board base by means of an intermediate polyethylene layer. The oxygen barrier polymerlayer, which preferably is EVOH, and the polyolefin layer are brought by coextrusion onto the MFC film. The film and the laminate according to the invention aim at an improved oxygen barrier in high humidity conditions and have use in oxygen-sensitive food packaging.

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.

An insulating insert for a packaging system includes six pockets and multiple sealed dividers. The six pockets are rectangular in shape and are each filled with an insulating material. The six pockets include a bottom pocket configured to contact a bottom inside surface of a box, four side pockets each configured to contact a respective side inside surface of the box, and a top pocket configured to contact a top inside surface of the box when the insulating insert is placed into the box. Each sealed divider is located between two adjacent pockets. The sealed dividers provide fold locations to permit the insulating insert to be folded and installed within the box so that each of the six pockets contacts a respective inside surface of the box.

Methods of making laminated paper sheets include winding paper around a flat-sided mandrel to form a flat-sided convolute tube and cutting from the flat-sided convolute tube one or more laminated paper sheets. The laminated paper sheets are alternatives to plastic, wood, and wood-like materials, such as plywood, medium-density fiberboard (MDF), and oriented strand board (OSB).

A container and a method of producing the container are disclosed, wherein the container is formed of a laminate having a base layer and a sheet.

A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

The present invention relates to a laminated cellulose-based liquid or semi-liquid food packaging material, comprising a bulk layer from cellulose fluting material, an outside substrate layer having a print surface and on the inside an aluminium foil barrier and a further barrier layer. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.
