Indentors Of Sack Kraft From Canada, Thailand And Europe

Kraft paper is paper produced from chemical pulp produced in the kraft process.The majority of all Kraft paper produced is used for cement packaging. This is our specialist field bringing the most suitable type of Kraft paper to that particular market. The invention of the Clupak process in papermaking allowed Kraft paper to be produced with additional stretch or extensibility, known as Extensible Sack Kraft. This grade is suited for cement packaging where optimal strength requirements are required. Further breakthroughs in paper technology such as high consistency refining and high porous papers contributed to reduction in number of plies and basis weight all leading to a more competitive and better performing product.

Fully Extensible or Semi Extensible

Semi Extensible Sack Kraft was a grade developed with the converting speeds in mind. A squarer sheet (meaning equal TEA in both CD and MD) results is more stability on the tuber thus higher productivity. Available in both Bleached and Unbleached.

High Porosity Sack Kraft

Applying peforation holes to cement sacks allows faster air escape during filling and therefore faster filling. The downside with this is an overally weaker sack (up to 15% weaker) and dusty cement packing station! High Porosity Sack Kraft was developed as a naturally porous paper making it not necessary to apply perforations to the cement sack. Immediately a stronger and cleaner sack was born!

Standard Sack Kraft

Produced without the clupak unit therefore non extensible. Can be used in non-intensive industries (Flour, Feed etc) such as open mouth sacks and lined sacks.
