Abstract:
The present invention relates to new compounds particularly for preparing polyurethanes. From the chemical standpoint, the compounds having the formula (I) are derivatives of N-acylurea. Due to the many variations at the levels of the radicals R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12 , the person skilled in the art can modify advantageously their chemical and physical properties, so as to allow the use of the compounds having the formula (I) in the most diverse situations and in combination with the most disparate reagents, yet maintain chemical stability and activity of interest. The compounds have proved themselves particularly useful to produce surface-active polyolefin films for the catalysis of the polyurethane forming reaction, in view of the high chemical compatibility achieved with the polyolefins on which they are deposited.
Abstract:
Die Erfindung betrifft einen Behälter (10), insbesondere Schlauchbeutel, Standbeutel oder dosenförmiger Behälter, mit einer Behälteröffnung (20), die durch ein lösbares, insbesondere peelbares, Verschlusselement (30) verschließbar ist, wobei an dem Verschlusselement (30) ein Trennelement (40) angeordnet ist, das sich in geschlossenem Zustand des Behälters durch die Behälteröffnung (20) hindurch und über einen von einem Hauptvolumen (50) des Behälters (10) abgetrennten Aufnahmeraum (60) unter Versiegelung desselben erstreckt.
Abstract:
A high-barrier multilayer laminated film, comprising at least: a first layer (11) made of polypropylene; a second layer (12) made of polypropylene or polyethylene; a third central layer (13) made of polyethylene vinyl alcohol (EVOH) , which is interposed between the first layer (11) and the second layer (12) and is joined to them by means of an intercalated layer (14) made of adhesive material, the first (11), second (12) and third (13) layers of which are co-extruded and stretched. The multilayer laminated film is well-suited for the production of pouches and other similar enclosures for the packaging of precooked and ready-to-eat foods.
Abstract:
A multilayer laminated film for packages, constituted by a first layer (11, 111, 211, 311, 411, 511, 611, 711) made of plastic material and by at least one second layer (12, 112, 212, 312, 412, 512, 612, 712, 213, 313, 413, 513, 613, 713, 614, 714) made of material chosen among plastic material, metallic material, paper-like material or equivalent materials; each layer is coupled to the adjacent layer by means of an intercalated layer (15) of adhesive material. The multilayer laminated film (10, 110, 210, 310, 410, 510, 610, 710) according to the invention has, on at least one face (16, 216, 416, 616, 117, 317, 517, 717) of the more rigid layer of plastic material (11, 111, 211, 311, 412, 512, 613, 713), a plurality of continuous, parallel, side- by-side incisions (18, 18a, 18b, 18c, 18d, 18e, 118, 218, 318, 418, 518, 618, 718), which are suitable to facilitate a reduction of the breaking load at right angles to the direction of the incisions (18, 18a, 18b, 18c, 18d, 18e, 118, 218, 318, 418, 518, 618, 718). The incisions (18, 18a, 18b, 18c, 18d, 18e, 118, 218, 318, 418, 518, 618, 718) are obtained by removing material and affect only partially the thickness of the more rigid layer.

Abstract:
A multilayer laminated film whose use is particularly suitable for the packaging of food which must undergo a high-temperature thermal treatment after packaging has occurred at least partly, the film comprising at least two layers (11, 12, 13), of which at least one first layer (11) is made of plastic material and is intended for heat-sealing and at least one second outer layer (12) is made of a material selected among plastic material, metallic material, paper-like material or equivalents; each layer is coupled to the adjacent one by means of an interlayer made of adhesive material (14, 15). The first heat-sealing layer (11) is of the type with a low-density cavitated structure.
