Highly compressed filter tow bale and method for the production thereof

This invention description has a is packaging of high compression of by filter silk beam constitute of State square tied package, in the tied package of top surface and end of surface Shang no interference of uplift or shrink, which, by in tied package has a at least 300kg/m3 of packaging density; by in tied package through a machinery since hosted of, and elastic of packaging material full package, which this material has a or multiple convection of gas key connection; by in tied package of top surface and end of surface is such to flat, makes in will is not open of tied package layout in a level plane Shang Shi, A full cover tied package of flat can through a in Middle role of 100N law to force extrusion to tied package of top surface Shang; and in maximum of rectangle internal, is located in above of tied package surface of area of at least 90% away from flat has a most about 40mm of distance, by in maximum rectangle can within received Yu tied package of in is extrusion of Board Shang of vertical projection in the, by in tied package surface is located in within received of rectangle internal; by in tied package has at least for 900mm of height, and, in tied package in the, at least in packaging zhihou, There is a negative pressure relative to the environmental pressures of at least 0.01bar. This invention relates to producing method of this bundle. For this bundle, as far as possible avoid the package crack subjected to internal pressure. It renders a perfect cube, so exclude as much as possible interference in transport bundles of uplift or to prevent the contraction of output filter tow.
