Kraft Liners

Manufactured from softwood trees, Kraft paper consists of 70-80% “virgin” chemical pulp fiber, which results in a top paper grade that is very stiff and durable. Kraft paper is the most sustainable option out of all the types of paper available, but it is also the most costly.

Options for kraft liners include:

• Brown Kraft – Varying natural brown color depending on the different fibers used, the pulping process, and the location of the paper mill.
• White Top Kraft – very strong and affordable and offers excellent printing characteristics.
• Mottled Kraft – Also known as Oyster Kraft. It is similar to White Top Kraft but has a mottled appearance.
• Fully Bleached White – A white Kraft liner with a natural look. It is put through an additional bleaching process to create a white surface. This paper grade is not as environmentally friendly as unbleached Kraft.
