摘要： The invention discloses a method for producing a packaging material and a packaging material suitable for packaging of food and/or liquid. In the method of the invention a first barrier layer, and an optional second barrier layer, is applied on a first side of a paperboard web. The thereby formed barrier coated web is at least partly dried in a first drying step, whereupon an extruded layer is applied onto the partly dried barrier coated web in a second coating step. In accordance with the invention, the first and second coating steps are applied integrated within the same coating line. The application of a first barrier layer and an extrusion coated layer in the same coating line in accordance with the invention has shown to give rise to a packaging material with remarkably good barrier properties, especially gas-, liquid and/or grease barrier properties, for the packaging of food and/or liquid.

摘要： A metering rod assembly including a body for accommodating a metering rod insert and configured to clamp the metering rod and/or metering rod insert without the use of an auxiliary clamping device, such as a pressure tube or the like. A rod bed insert is supported in a tapered channel of a body whereby a clamping action is created during use. In another embodiment, the body includes a hinge portion that facilitates relative rotation between upper and lower jaws to create a clamping action during use.

摘要： An apparatus for distributing a hydrophobic material in a substrate includes a first roller, second roller that engages the first roller to form a nip, a heater operatively connected to the first roller and configured to heat the first roller to a first temperature that is greater than a second temperature of the second roller, and a substrate transport configured to move a substrate through the nip at a predetermined velocity. The first roller engages a first side of the substrate and the second roller engages a second side of the substrate to enable the hydrophobic material to penetrate into the substrate.

摘要： A method for enhancing the structural strength of a porous substrate having pores therein is disclosed. The method includes soaking the porous substrate in a solution having a first solvent and at least one polymer dissolved in the first solvent at a specific temperature and pressure, such that the solution is deposited within pores of the porous substrate, soaking the porous substrate in a second solvent, such that the first solvent diffuses into the second solvent, and such that the at least one polymer remains within the pores of the porous substrate, and flushing out the second solvent from the porous substrate.

摘要： The present invention describes methods of treating cellulosic materials with a composition that provides increased hydrophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for esterification of available hydroxyl groups on cellulosic materials, where such hydroxyl groups are “masked” by bulky organic chains, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.
