The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

A machine for making insulation may include two or more rotatory members configured to pull a precut insulation product at a first rate, wherein the precut insulation product comprises a first paper layer, a second paper layer, and a continuous paper core sheet, a first restraint and a second restraint spaced apart a predetermined distance to create a first space therebetween, and two or more second rotary members configured to feed a continuous paper sheet at a second rate into the first space such that the continuous paper sheet forms a plurality of flexible loops defining a plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction. The first rate may be slower than the second rate.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.

The adhesive composition comprising emulsion polymers and microspheres and articles made therefrom are provided. The adhesive is particularly suitable for packages for consumer products that provide sufficient strength and thermal insulation while reducing the overall basis weight of the substrates.

A biodegradable packaging material, a method of manufacturing the same, as well as products made of the material wherein the manufacture comprises extrusion onto a fibrous substrate one or more polymer coating layers including at least one layer of a polymer blend consisting of (i) 20-95 wt-% of polylactide having a high melt index of more than 35 g/10 min (210° C.; 2.16 kg), (ii) 5-80 wt-% of polybutylene succinate (PBS) or a biodegradable derivate thereof, and (iii) 0-5 wt-% of one or more polymeric additives. The components of the blend are melted and blended in connection with the extrusion step. The goal is to improve extrudability, increase machine speed in extrusion and maintaining good adhesiveness to the substrate and good heat-sealability of the coating. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.

A method for producing an insulation material is described herein. The method includes mixing cellulose reinforcement fibers with thermoplastic binder fibers to form a mixture. In addition, the method includes applying heat to the mixture to melt the thermoplastic binder fibers such that the thermoplastic binder fibers bind the cellulose reinforcement fibers together to form a batt. The thermoplastic binder fibers make up about 0.5% to about 25% by weight of the batt. Furthermore, the method includes slicing the batt along a horizontal plane to form a first pad having a first thickness and a second pad having a second thickness. Each of the first and second thicknesses is greater than or equal to about 1/16 of an inch.

The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

A sheet structure, fabricated from paper and/or paperboard material, provides a thickness dimension ordinarily associated with corrugated paperboard material. The sheet structure is constructed from a first planar linerboard sheet and a second non-planar linerboard sheet, wherein a plurality of projections are cut and folded from the second linerboard sheet and are adhesively coupled to the first linerboard sheet, such that portions of the projections define a standoff between the first and second linerboard sheets.

The present invention refers to a sheetlike composite (100), comprising as a layer sequence in a direction from an outer surface (101) of the sheetlike composite (100) to an inner surface (102) of the sheetlike composite (100) a) an outer polymer layer (103), b) a colour application (104), c) a carrier layer (105), and d) a barrier layer (107);
wherein the outer polymer layer (103) is characterised by a density in a range from 919 to 925 kg/m.sup.3. The invention further refers to a container precursor (500) and to a container (700), in each case comprising at least part of the preceding sheetlike composite (100); to processes (300, 400, 600) for preparing a sheetlike composite (100), a container precursor (500), and a closed container (700); to the preceding products; and to uses of the sheetlike composite (100), and of a polyolefin.
