In certain embodiments, a hose includes an inner tube, a filler material, and an outer cover. The inner tube has a cross-sectional shape and includes a cavity for transporting a substance. The filler material is provided around an outer periphery of the inner tube. The filler material includes a self-sealing material or a self-healing material. The outer cover is provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube. The outer cover has a D-shaped cross-sectional shape.

The invention relates to a method (100) for controlling a film production in which at least one film is produced depending on at least one specific recipe information (R), where the following steps are performed: providing different fingerprints (F), the fingerprints (F) characterizing different method executions (210) for producing a film, providing in each case at least one result information (E) for the respective fingerprint (F), the result information (E) being specific for at least one product property (D) of the produced film, storing the fingerprints (F) and result information (E) as data in a data system (200) so that the data is provided as a basis for evaluation for controlling at least one subsequent method execution (210).

Methods and systems of measurement for blown film lines are provided. The sensing system includes a terahertz (THz) sensor positioned adjacent to a film bubble extruded from a blown film die, and a sensor support configured to guide the THz sensor around the circumference of the film bubble to measure its film thickness.

A transparent thermoformed high barrier plastic bottle is provided for use in storing food and beverages, personal care products, health care products, and other applications that require excellent transparency and barrier properties. The transparent thermoformed high barrier plastic bottle includes first and second outer layers formed using a transparent polyester or polyester copolymer; an inner nanolayer sequence including a plurality of nanolayers a) including ethylene vinyl alcohol, alternating with nanolayers b) including at least one of ethylene ethyl acrylate, low density polyethylene and linear low density polyethylene, each of the nanolayers b) having a degree of crystallinity less than about 45%; and adhesive layers between each of the two outer layers and the inner nanolayer sequence. A method for producing a transparent thermoformed high barrier plastic bottle is also provided.

The invention relates to an apparatus and to a method for film production and/or film processing, characterized by a device for determining the flatness and/or evenness of the film and for further processing and/or outputting the determined results.

A method of manufacturing a blown film (F) comprising extruding it through a die (D), flattening the film with a folding angle that varies, measuring a transverse profile of a characteristic property of the blown film, which property is summed over two juxtaposed portions of a wall of the flattened film, and estimating a polar profile on the basis of said transverse profile, the method further comprising determining polar positions of the periphery of the flattened blown film that correspond to a transverse position of the film, determining discretized angle values flanking each of the polar positions, and, on the basis of said discretized angle values, computing interpolation coefficients that associate the polar profile of the film with a discretized polar profile of the film, and, based on said interpolation coefficients, updating the estimation of the discretized polar profile of the film by applying a Kalman filter.

The invention describes a blown foil system for producing a foil web with at least one extruder for providing a melt-like plastic, a blowing head with a circumferential die gap, with which the melt-like plastic can be transformed into a foil bubble emerging from the die gap, with at least one liquid cooling device for cooling the foil bubble, wherein a liquid can be supplied to the outer periphery and/or to the inner periphery of the foil bubble by means of the liquid cooling device, with a flat laying device by means of which the foil bubble can be formed into a double-layer foil web, wherein the two layers are in contact at least partially and in particular substantially over the full surface, and with at least one stretch unit for stretching the foil web in the longitudinal direction.
