This paper needs a high tensile strength in the machine direction, which is the axial direction of the cartridges. Both white and brown grades are made. The raw material is normally softwood pulp from the kraft process. The paper is microcrepped to give porosity and elasticity.
The long fibers provide the paper its strength and wet strength chemicals are added to even further improve the strength.
Absorbent kraft paper is made with Brown kraft paper absorbency, i. This paper requires the best possible machine direction strength and cross machine elongation. The kraft process can use a wider range of fiber sources than most other pulping processes.
Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.
In the cross direction, the cartridge is supported by the gun-pipe, but a sufficient elongation is needed. Twisting paper is mostly opaque and often supercalendered.
It has high tensile strength. This is done by high fiber orientation on the papermachine. Qualities[ edit ] Normal kraft paper is strong and relatively coarse. Kraft paper is produced on paper machines with moderate machine speeds. Sack paper is then produced on a paper machine from the wood pulp.
All types of wood, including very resinous types like southern pine and non-wood species like bamboo and kenaf can be used in the kraft process.
Hunting cartridge paper is a kraft paper used in shotgun shells. Kraft process and Paper machine Wood pulp for sack paper is made from softwood by the kraft process. Microcrepping is done by drying with loose draws allowing it to shrink.
These papers require a good strength, with highly oriented fibers. It is made of clean low kappa hardwood kraft and has to have a good uniformity and formation.
A paper sack can be made of several layers of sack paper depending on the toughness needed.Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.
Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Uline stocks a wide selection of Kraft Paper Rolls. Order by 6 pm for same day shipping.
