A method for packaging a cushion includes coating a cushioning element with a powder while the cushioning element is in an expanded state and then compressing the cushion to a compressed state. As the cushioning element is compressed, the powder prevents surfaces of the cushioning element (e.g., surfaces of intersecting walls that define hollow buckling columns of a cushioning element formed from an elastomeric polymer extended with a plasticizer, etc.) from adhering to each other. The powder may allow the cushioning element to substantially return to its expanded state substantially immediately following removal of a compressive force from the cushioning element.

The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.

An electrical wire includes a conductor and an insulating layer that covers the conductor and that is cross-linked. The insulating layer is a cross-linked product of a resin composition including (a) a base polymer containing polyolefin and a compatibilizer, (b) a photoradical generator of 0.5 parts by mass or more and 3 parts by mass or less relative to the 100 parts by mass of the base polymer, and (c) a reactive monomer of 1 part by mass or more and 5 parts by mass or less relative to the 100 parts by mass of the base polymer. A relative dielectric constant of the insulating layer is less than 2.5.
