The present invention provides an adhesive resin composition that is used for adhesion of a fluorine-based resin and is aimed at adhesion between fluorine-based resins or between a fluorine-based resin and a material other than a fluorine-based resin. More specifically, the present invention relates to an adhesive resin composition for use in adhesion of a fluorine-based resin, the composition including a polyethylene-based resin, an elastomer component, and a component having an epoxy group and a vinyl group, wherein a content of the polyethylene-based resin is 55 parts by mass or more and 90 parts by mass or less, a content of the elastomer component is 10 parts by mass or more and 45 parts by mass or less, the elastomer component and the component having an epoxy group and a vinyl group have a common repetition unit, and a content of the component having an epoxy group and a vinyl group based on a total amount of 100 parts by mass of the polyethylene-based resin and the elastomer component is 0.1 parts by mass or more and 1.5 parts by mass or less.

The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.

The invention relates an adhesive tape, particularly wrapping tape for wrapping cables in automobiles, comprising a textile carrier, and an adhesive coating on at least one face of the carrier, characterized in that the textile carrier is produced, at least to some extent, from bio-based polymers.

A multilayered structure that includes an olefin resin layer and a gas-barrier layer. An adhesive layer is provided adjoining the olefin resin layer and the gas-barrier layer, the adhesive layer consisting of an acid-modified olefin resin. The acid-modified olefin resin has methyl branches in a number of 10 to 200 per 1000 carbon atoms on a main chain thereof, and has not more than 50 branches that are larger than the methyl groups.
