Santa Maria’s goal is to produce quality white Kraft papers

Kraft paper is a type of paper that has in its composition a mixture of short fibers and long fibers. The presence of long fibers give the paper greater mechanical strength and plasticity. These properties are of extreme importance for the applications that this paper is mainly used for, such as production bags and sacks. The presence of short fibers in the paper grants it characteristics such as softness and printability.

The Santa Maria Co. SaMa Kraft white paper is produced with the alkaline bonding process, which replaced the acidic bonding process, a technology that Santa Maria pioneered. Some characteristics this paper have been improved, such as:

  • Greater whiteness;
  • Greater brightness;
  • Greater durability (aging, reversal of whiteness and material degradation);
  • Greater dimensional stability.

This characteristic of greater whiteness and brightness has yielded many benefits, especially to clients who use SaMa Kraft white paper for printing and manufacturing of bags to package food, wheat flour, milk powder, seals, among others.

Santa Maria produces white Kraft paper in two types:

SaMa KRAFT MG: one of the sides are smoother and brighter, which provides greater printability and glossiness on the print, very important details for the packaging market, especially with bags.

SaMa KRAFT MF: both sides present a relatively rougher texture, an important characteristic mainly for the market of sacks for seeds, animal feed, and chemicals, among others. With greater roughness, the sacks can be stacked without displacement during transportation and storage.

Direction of Fiber on Paper

During the papermaking process, the fibers tend to be arranged in the direction of the pressure screen´s movement. Because of this, we can say that, in relation to the direction of the fibers, the paper can be distinguished by two directions: Longitudinal and Transversal. The cellulose fiber has hygroscopic characteristics, that is, it either absorbs […]

Acid-free paper, white for much longer…

Every line of Santa Maria paper is of acid-free paper. Do you know what the advantage of this is? To better understand this feature we need to first understand the definition of paper bonding. Paper bonding consists of reducing or retarding the water penetration in the paper without waterproofing it. Paper used for printing or […]
