Abstract: A self-adhesive tape comprising an oriented polyolefin film, one side of which is coated with an adhesive layer formed from a mixture of 30-65 wt. % of a natural rubber latex and 35-70 wt. % of an aqueous dispersion of a hydrocarbon resin, and the opposite side of which has no surface treatment.

Abstract: An adhesive tape comprising a polyvinyl chloride film having an adhesive layer formed from a mixture of a natural rubber latex and a dispersion of an aromatic modified hydrocarbon resin.

Abstract: The invention relates to a hologram carrier having a hologram surface and a reference surface to facilitate the acquisition of the hologram surface by a device. In this case, provision is made for the reference surface to comprise at least one step, which is arranged to interengage with a complementary formation on the device in order to align said device.

Abstract: A packaging tape (3) which comprises a polymer film is used as a holographic data carrier. The packaging tape (3) is set up for the storage of holographic information. Holographic information can be put into the packaging tape (3) with the aid of a writing device (4), before an object (1) is packaged by using the packaging tape (3), but also afterwards.

Abstract: A solvent-free adhesive tape with a film based on polyolefins and an adhesive layer which is applied at between 10 and 45 g/m2 and is prepared with a mixture comprising an adhesive acrylic dispersion acquires improved adhesive properties and increased water insensitivity by virtue of the fact that the mixture comprises a second, special acrylic dispersion, the quantitative ratio between the first acrylic dispersion and the second acrylic dispersion being between 99:1 and 90:10 and the second acrylic dispersion comprising the following components: 65-84% by weight of ethyl acrylate units 15-34% by weight of methyl methacrylate units 0.5-2% by weight of acrylic acid units 0.1-1% by weight of propyleneimine units.

Abstract: A multilayer adhesive tape having a backing based on an oriented thermoplastic film, whose upper face is coated, if desired, with a release coating and to whose lower face the following layers have been applied: a) a primer layer which is not applied over the full area and which anchors very well to the thermoplastic film, b) a first release layer which is applied over the full area of the applied primer layer, and the free thermoplastic film surface, the first release layer anchoring better to the primer layer than to the thermoplastic film, c) a second release layer which is applied over the full area of the first release layer and which is anchored better on the first release layer than the first release layer on the film surface and which has worse adhesion to the first release layer than adhesive composition to the adhesion substrate, d) a pressure-sensitive adhesive composition which is applied over the full area of the second release layer and which is anchored better on the second release layer th

Abstract: A multilayer plastic composition having (I) an outer layer of a thermoplastic molding composition and (II) an inner layer of an electrically conductive thermoplastic molding composition containing graphite fibrils, which are useful for the transport of (petro) chemical materials and also in the motor vehicle sector for conveying brake, cooling and hydraulic fluid and also fuel.

Abstract: A plastic pipe based on polyolefins is provided, which pipe, compared with single-layer pipes of polyolefins, has improved barrier action against (petro)chemical materials, in particular against methanol-containing fuels. This is achieved by a multilayer plastic pipe which comprises the following layers: I. at least one layer based on a polyolefin, II. at least one layer based on a thermoplastic polyester, bonded via III. a layer between them of a suitable coupling agent which contains reactive groups, with adjacent layers being cohesively bonded to one another. The invention makes it possible to obtain plastic pipes having the desired improved property profile.
