Definitions
- the invention relates to a method and a device for producing packaging paper, in particular sack kraft paper.
- Sack paper also called sack kraft paper
- Sack paper is made of pulp fibers and predominantly of long fiber pulp, since this brings a high strength and a high porosity of the paper with it.
- Sack paper becomes sacks .B. for the packaging of cement and powdered products.
- the main characteristics of the sack paper include high strength with sufficient elongation, high porosity and sufficient rigidity. Such properties are crucial only in terms of the load on the bags during transport, but also with regard to the loading of the bags during filling.
- the sack kraft paper grades are a niche product in the field of packaging papers. Unbleached varieties are produced with existing machines based on several different machine concepts. In this case, expandable sack kraft paper grades are also already using a so-called "Extensible Unit", known for example as a Clupak unit, manufactured as a compression device with an elastic band, is creped through the still moist fibrous web to improve their elongation properties in the web running direction.
- the invention has for its object to provide a method and an apparatus for the production of packaging paper, in particular sack kraft paper, with which the investment and operating costs are minimized while maintaining a high quality of the packaging paper produced.
- this object is achieved by a process for the production of packaging paper, in particular sack kraft paper, in which pulp suspension is thickened in a stock preparation to a solids concentration in the range of about 30% to about 35% before high consistency milling, the fibrous web after the high consistency milling of a low consistency grinding at a solids concentration in the range of about 1% to about 3%, the pulp suspension by means of a headbox with a consistency ⁇ 0.5%, in particular having a consistency in the range of about 0.15% to about 0.25%
- Dewatering and formation of a fibrous web is applied to the wire of a Fourdrinier or a hybrid former, the wire is stimulated in particular in the initial sheet forming area to shaking, and the formed fibrous web is further dewatered in a press section and dried in a dryer section.
- the thickening of the fibrous web preferably takes place by means of a screw press or by means of a twin-wire press.
- a Hybridfomer has a wire on which the fibrous web is dewatered in the initial area only to one side. After the initial region, the fibrous web is dewatered between a second dewatering wire and the longitudinal wire lying on both sides.
- Hybrid shapers are available at higher speeds of the paper machine advantageous. The drainage performance is thereby increased without affecting the quality of the fibrous web produced. With the thickening, the amount of water contained in the fibrous web is reduced, resulting in a correspondingly higher consistency of the fibrous suspension, which indicates the percentage of dry matter still present in the fibrous stock suspension. High-consistency milling at a solids concentration in the stated range increases the strength of the later-formed packaging paper web.
