2021 kraft paper packaging industry market prospects and analysis

What Kraft Paper Is

Kraft paper is a strong paper made from softwood pulp using a Fourdrinier paper machine. It is typically yellowish brown in color and used for packaging, bags, and wrapping. It has high tensile strength, tear strength, and rupture work, with a fracture length generally above 6000 meters.

Common Uses of Kraft Paper

Kraft paper is used in cement bags, envelopes, glue sealing paper, asphalt paper, cable protection paper, insulation paper, and food packaging. Its strength makes it suitable for carrying heavy or bulky items without tearing.

Paper Weight and Physical Properties

Kraft paper typically ranges from 80 to 120 gsm. It is available as roll paper or flat paper. The material maintains its strength even when exposed to moisture, though moisture resistance varies based on treatment and application.

Color Variability in Kraft Paper Rolls

Color differences in kraft paper rolls are common due to raw material sources, production batches, seasons, and machines. Same batch rolls can maintain 98% color consistency. The base color is usually yellowish brown, but semi-bleached or fully bleached versions can be light brown, cream, or white.

Printing on Kraft Paper

Kraft paper can be printed using flexo, gravure, offset, or screen printing. Success depends on understanding ink printability, controlling equipment parameters, and selecting inks suitable for the paper's surface and intended use.

Kraft Paper in Food and Beverage Packaging

For food packaging, kraft paper’s tensile strength prevents bags from tearing during handling. Beverage packaging requires resistance to moisture and deformation. Frozen food packaging demands materials that retain integrity under low temperatures.
