    摘要： The tape comprises a substrate in the form of an olefinic polymer film, a pressure-sensitive adhesive layer on one face of the substrate, and a printable, non-stick layer on the other face of the substrate. The non-stick layer is formed by a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin may vary from 4:1 to 1:4. The composition also includes from 0.1 to 2 parts by weight of a non-stick agent per 100 parts by weight of the sum of the first two components, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a reactive silicon compound.

    摘要： A multilayer, polyolefin, bi-axially oriented film comprises at least one base layer, a first intermediate layer, a first cover layer and a second cover layer disposed on the opposite side from the first cover layer and the first intermediate layer with respect to the base layer. Antifog additive is contained at least in the base layer and in the first cover layer. In the film the ratio between the thickness of the first cover layer and the thickness of the first intermediate layer is greater than 1 and lies between 1 and 2 and the surface tension of the face of the film belonging to the first cover layer is greater than the surface tension of the other face of the film belonging to the second cover layer.

    摘要： A pressure-sensitive and printable self-adhesive tape of the type including a substrate in the form of a polyolefin film has a release layer deposited on one face of the substrate, including from 50 to 62 parts by weight of polyamide resin produced by the condensation of fatty acid dimers and/or trimers with diamines and/or triamines, from 30 to 42 parts by weight of ketone resin, and from 5 to 10 parts by weight of a release agent constituted by a polyvinyl carbamate obtained from stearyl isocyanate and a polyvinyl alcohol having a Brookfield viscosity of between 5 and 45 cPs (20-45 10⁻³ Pascal seconds). In order to prevent set-off phenomena, particularly for self-adhesive tapes in which the adhesive layer is of the type with a solvent, a commercially-available type of polyamide ink is used with a polyvinyl carbamate additive produced from a polyvinyl alcohol having a preferred viscosity of between 4 and 6 cPs (4-6 10⁻³ Pascal seconds).
