An adhesive tape for jacketing an elongated item, more particularly cable sets, comprises a tapelike carrier which is characterized in that the tapelike carrier is provided on at least one side with a binder which is thermally softenable at a temperature of 50° C. to 100° C. and comprises a polycaprolactone.

A dielectric welding film capable of providing excellent adhesiveness to a variety of adherends in a short period of dielectric heating, and an welding method using the dielectric welding film are provided. The dielectric welding film is configured to adhere a pair of adherends of the same material or different materials through dielectric heating, the dielectric welding film including a first thermoplastic resin as an A1 component having a predetermined solubility parameter, a second thermoplastic resin as an A2 component having a solubility parameter larger than the solubility parameter of the first thermoplastic resin, and a dielectric filler as a B component. The welding method uses the dielectric welding film.

The adhesive tape, in which delamination hardly occurs even when a laminate layer is thin, includes: a base material 1 of a warp-knitted fabric in which a weft yarn 11 is inserted into a loop structure formed by a multifilament warp yarn 12; a first laminate layer 2 formed on a first surface 1A of the base material 1 where one warp yarn appears on the surface of the weft yarn; a second laminate layer 3 formed on a second surface 1B of the base material 1 on which two warp yarns appear on said weft yarn surface; and an adhesive layer 6 formed on the side of the first laminate layer 2.

A degradable EVOH high-barrier composite film, characterized in that the materials of various layers in the composite film all obtain approximately-consistent biodegradability by introducing biomass, and the additive amount of the additive master batch in the materials of each layer is controlled within the range of 0.3-15% of the total mass of the materials of the corresponding layer; the hydrophilic activity of the hydrophilic groups in the additive master batch should be greater than or equal to that of the hydrophilic groups in the materials of each layer; by adding the additive master batch, the mole ratios of the hydrophilic groups to carbon atoms of the materials of various layers tend to be consistent, namely, the bioactivities tend to be consistent, so that the degradation rates of the materials of various layers in the composite film tend to be consistent. The present invention makes contribution to obtaining approximately-consistent bioactivities and approximately-consistent biodegradation rates by balancing the mole ratios of the hydrophilic groups to carbon atoms in the materials of various layers, and the appearance, the functions and the physical and mechanical properties of a product remain unchanged.

A release sheet 1 may include a base material 12 and a release agent layer 11 provided on the base material 12. The release agent layer 11 is composed of a cured product of a release agent composition containing 50 mass % or more of a diene-based polymer. Mooney viscosity (ML.sub.1+4 (100° C.)) of the diene-based polymer measured at 100° C. according to HS K6300 is in the range of 25 to 70, and a ratio (T.sub.Cp/ML.sub.1+4 (100° C.)) of the Mooney viscosity (ML.sub.1+4 (100° C.)) and a viscosity (T.sub.Cp) of a toluene solution of the diene-based polymer is 2.2 or less. This makes it possible to provide a release sheet which can sufficiently suppress adverse effects on electric components and the like, which has a small dependence of release force on peel rate and which can suppress the occurrence of zipping phenomenon, and a pressure-sensitive adhesive article having such a release sheet.
