The Grande Prairie mill has access to spruce and pine, producing pulp with superior tensile strength, surface smoothness, cleanliness, and uniformity with low refining energy requirements. It is especially suited for premium tissue and towel applications, as well as premium paper and specialty applications.
Southern Bleached Softwood Kraft (SBSK)
Fully bleached Southern kraft pulp is manufactured at International Paper mills in Riegelwood, NC and Columbus, MS. These grades of Southern pine fibers have high brightness, have exceptional balance of tear and tensile strength, and provide bulk, making them suitable for a variety of tissue, paper, and packaging applications. They are FDA compliant for food contact.
Helix fiber starts with a bleached kraft feedstock from our Southern system of mills and is modified at plants in Columbus, Mississippi and Gdansk, Poland. These curly fibers are an excellent addition to a paper or board furnish to provide a tool to manage bulk, caliper and basis weight.
