Abstract: A single or multilayered film is presented having at least one layer that contains at least one thermoplastic olefin homo or copolymer, modified if need be. The layer contains additionally, at least one polyester. Such film is used as a sliding film or preliner in trenchless pipe renovation using the tube lining technique in which the film is layed on the inner wall of an underground sewer pipe laid that will be renovated. An insertion pipe with a curable carrier material can be pulled in sliding fashion over the sliding film laid on the pipe.

Abstract: A tubular film with one or more layers is provided, wherein at least one of the two external sides of the tubular film has a coating at least in sections with at least one polysiloxane and/or a coating and/or covering with at least one migrating compound.

Abstract: A polymeric multilayer film having at least one polyamide layer as well as at least one further layer of a different polymeric material, the multilayer film having high elasticity and good flexibility.

Abstract: A multilayered film is provided, especially in form of a tubular film for use as preliner in trenchless sewage pipe renovation that uses the pipe lining process. The multilayered film has at least one layer (a), which contains at least a homo- or co-polyamide with a proportional weight expressed in percent of more than 25% by weight, preferably as external layer, as well as by at least one layer (b) containing at least one thermoplastic, if need be modified, olefin homo- or copolymer and/or by at least one layer (c) containing at least one thermoplastic elastomer (TPE). Various uses of the multilayered film according to the invention are suggested as well.

Abstract: A film suitable for permanent, firm bonding with resin after hardening of the resin is provided with at least one layer containing at least one polyolefin plastomer (POP) or one polyolefin elastomer (POE) capable of bringing about a permanent, direct adhesion of the resin to this layer during the course of resin hardening. The invention likewise refers to an arrangement with at least one such film and a resin on one side of the film. The invention also refers to a tube liner for non-disruptive sewage pipe renovation and various applications of the film according to the invention or the arrangement according to the invention in non-disruptive sewage pipe renovation.

Abstract: The invention refers to a multilayered film, especially in form of a tubular film for use as preliner in trenchless sewage pipe renovation that uses the pipe lining process. The multilayered film according to the invention is characterized by at least one layer (a), which contains at least a homo- or copolyamide with a proportional weight expressed in percent of more than 25% by weight, preferably as external layer, as well as by at least one layer (b) containing at least one thermoplastic, if need be modified, olefin homo- or copolymer and/or by at least one layer (c) containing at least one thermoplastic elastomer (TPE). Various uses of the multilayered film according to the invention are suggested as well.

Abstract: The invention refers to a multilayered film, preferably in form of a tubular film, with a layer sequence made up of at least the following layers: At least one layer (1) containing at least one homo- and/or copolyamide, preferably as one of the external layers, at least one adhesive promoter layer (2), (4), and at least one additional layer (3), (5), preferably as one of the external layers. The multilayered film according to the invention is characterized by the fact that it contains in the at least one adhesive promoter layer (2), (4) and/or the at least one additional layer (3), (5) at least one ethylene(meth)acrylate copolymer, in functionalized or non-functionalized form. In addition, uses of such a multilayered film are presented as well as an insertion tube for trenchless sewage pipe renovation that includes such a multilayered film.

Abstract: A one- or multilayered film is presented, in which case the film comprises at least one layer that contains at least one thermoplastic olefin homo or copolymer, modified if need be. According to the invention, said layer contains additionally, at least, one polyester. In addition, the use of such film as sliding film or preliner in pipe renovation using the so-called tube lining technique is presented, in which case the film is used for laying it on the inner wall of a pipe laid underground that will be renovated, preferably a sewer pipe, so an insertion pipe with a curable carrier material can be pulled in sliding fashion over the sliding film laid on the pipe. The film according to the invention can also be used as packaging material for food or for the so-called non-food sector.
