Cardboard Color Paste

Updated: 2026-08-18

Overview

Cardboard pigment is a specialized coloring agent designed for dyeing cardboard and paper products. It is widely used in the packaging industry to produce vibrant and uniform colors on cardboard surfaces. The pigment can be water-based or solvent-based, depending on the manufacturing requirements and environmental considerations. Its formulation ensures excellent adhesion to cellulose fibers, providing long-lasting color even under mechanical stress. The pigment is favored for its cost-effectiveness and ability to meet stringent industry standards for color consistency and durability.

Physical and Chemical Properties

Cardboard pigments are typically available in liquid or paste forms, with densities ranging from 1.1 to 1.3 g/cm³. They exhibit high color strength and lightfastness, ensuring the colors remain vibrant even after prolonged exposure to light. The solubility varies between water-soluble and solvent-based formulations, catering to different production needs. Key properties include excellent adhesion to cellulose fibers, resistance to bleeding, and compatibility with various paper-coating processes. These pigments are engineered to withstand the mechanical stresses encountered during cardboard production, such as cutting, folding, and printing.

Main Applications

The primary application of cardboard pigment is in the paper and packaging industry, where it is used to color cardboard for boxes, cartons, and other packaging materials. It is also employed in the production of colored paper for artistic and decorative purposes. In addition to packaging, these pigments are used in specialty papers, such as gift wraps and greeting cards, where vibrant and consistent colors are essential. Their versatility makes them suitable for both large-scale industrial applications and smaller, custom projects.

Safety and Storage

Cardboard pigments should be handled with care to avoid skin and eye contact. Protective gloves and goggles are recommended during use. Ensure proper ventilation to prevent inhalation of fumes, especially with solvent-based formulations. Storage conditions are critical to maintaining the pigment's quality. Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep containers tightly sealed to prevent evaporation or contamination. Always follow the manufacturer's safety data sheets (SDS) for specific handling and disposal guidelines.

B2B Procurement Guide

When procuring cardboard pigments, B2B buyers should consider factors such as color consistency, adhesion properties, and environmental compliance. Verify the pigment's compatibility with existing production processes to avoid operational disruptions. Request samples for testing before placing bulk orders. Evaluate suppliers based on their ability to meet delivery timelines, quality assurance standards, and technical support. Price ranges vary, but bulk purchases often come with discounts. Always check for certifications like REACH or ISO to ensure the product meets regulatory requirements.
