| 20110154779 | PACKAGING AND FILLING MACHINE - To provide a packaging and filling apparatus for keeping pressure of filled liquid food in a tube at positive pressure, facilitating preformation by a forming flap, and preventing an external ambient substance from entering the tube even if the liquid food pressure lowers to negative pressure by a fluctuation of the liquid food pressure. The packaging and filling apparatus has a pressure flange provided below a liquid level in a tubular packaging material and along an outer periphery of a filling pipe. The pressure flange prevents the filled liquid food in the tube from freely flowing up from the lower part to keep the pressure of the liquid food positive in the tube below the pressure flange so as to facilitate the preformation by the forming flap. A covering means is provided, for closing a gap occurring on a seam serving as a vertical sealed part or a portion where the gap might occur. | 06-30-2011 |
| 20100112255 | PACKAGING LAMINATE, METHOD FOR MANUFACTURING OF THE PACKAGING LAMINATE AND PACKAGING CONTAINER PRODUCED THERE FROM - A barrier film for packaging food or beverage comprises a polymer base film, and a barrier layer comprising an inorganic oxide applied onto the base film by vapour deposition. The inorganic oxide layer is further coated with a healing layer of a crosslinked organopolysiloxane which is covalently bound to the inorganic layer. Other aspects disclosed here involve a multilayer packaging laminate comprised of the barrier film, and a method of manufacturing the barrier film and packaging containers manufactured from the film. | 05-06-2010 |
| 20100016137 | PROCESS OF MANUFACTURING SEALED PACKAGES CONTAINING A POURABLE FOOD PRODUCT AND PACKAGING EQUIPMENT FOR PERFORMING SUCH PROCESS - A process of manufacturing sealed packages containing a pourable food product from a web packaging material moving along a predetermined path involves providing a recurring pattern of printed register marks on the web packaging material, applying a recurring pattern of bend or fold lines on the web packaging material as a function of the detected position of the printed register marks, generating new references, distinct from the bend or fold lines, on the web packaging material in a synchronized way with the application of the recurring pattern of bend or fold lines; and performing one or more subsequent operations on the web packaging material based on a synchronization pulse created by detection of the new references. | 01-21-2010 |
| 20090071103 | Method in hot filling of foods in a packaging container, as well as an apparatus therefor - A method involving the hot fill of foods in packaging containers constructed from a paperboard laminate comprises the food being filled in the packaging container with at least one component at a temperature of at least 80° C., but below 100° C., whereafter the packaging containers are closed and sealed and the packaging containers with their food contents are thereafter held hot during a predetermined period of time by contact with a heat holding medium at a temperature of at least 80° C., but below 100° C. The heat holding medium is present substantially in gas and/or vapour phase. An apparatus involving the hot fill of foods Information Disclosure Statement also disclosed. | 03-19-2009 |
