Brown kraft paper
Product Features
A packaging paper made primarily from high-quality unbleached softwood pulp, formed on a fourdrinier wire and processed with high-strength calendering.
Core Features
High strength: Excellent burst, tensile, and tear resistance; superior load-bearing and impact resistance.
Natural & Eco-Friendly: Made from unbleached pulp, free from fluorescent whitening agents, with a natural brown color. Fully biodegradable and recyclable.
Good stiffness: Crisp paper, resistant to deformation, withstands folding and pressure, good forming effect.
Printability: Stable ink absorption, suitable for single-color and two-color printing, as well as hot stamping and embossing processes.
Water & Moisture Resistance: Good resistance to water and moisture penetration.
Product Applications
Food packaging: packaging and bag making of clean food products such as baked goods, fast food, tea, nuts, and other similar applications.

What is the Difference between White and Brown Kraft Paper?
We all know that the clearest difference between them is their color, however, do you know why their color makes them so different?
Brown Kraft Paper
Made from unbleached sulfate pulp, retaining natural lignin and wood fibers. The characteristic brown color comes from the lignin content during the pulping process (kraft process), with minimal chemical treatment. Brown kraft paper generally has higher tensile and tear strength due to intact lignin bonds, making it ideal for heavy-duty packaging (e.g., industrial sacks, and shipping envelopes). Brown is preferred for non-food industrial uses (construction wraps, corrugated liners), eco-friendly bags, and applications where aesthetics are secondary to strength.
White Kraft Paper
Produced by bleaching brown pulp (e.g., using chlorine-free TCF/ECF methods) to remove lignin and impurities. This creates a bright, uniform appearance but slightly reduces fiber strength compared to unbleached kraft. White kraft paper, while still strong, may sacrifice minimal mechanical properties during bleaching but compensates with enhanced smoothness and printability. Dominates food-grade packaging (FDA-compliant variants), bakery wraps, medical packaging and consumer goods requiring a hygienic, visually appealing finish.
