Why can kraft paper be made grey?

Zeal X Gray Kraft Paper Bags are made from eco-friendly, high-quality kraft paper material. The premium kraft paper ensures the reliability and security of the packaging, while the elegant gray appearance and excellent texture add a refined touch. Kraft paper is known for its excellent tear resistance, high strength, and sturdiness, making it safer than traditional envelopes. Additionally, waterproof material customization is available, providing enhanced protection for your products.

1. Natural Color of the Raw Materials

Kraft paper is typically made from wood pulp or other plant fibers, such as straw or bagasse. These raw materials have a natural brown or yellowish tone. During the production process, kraft paper retains this natural color, resulting in the traditional "kraft" appearance.

2. Adding Gray Dyes

To create gray kraft paper bags, manufacturers can add gray dyes or pigments during the paper production process. These dyes are typically natural and meet environmental standards, ensuring that they do not affect the paper's biodegradability. This process allows the natural brownish tone of the kraft paper to be altered to gray or other shades.

3. Non-Bleached Processing

One of the key features of gray kraft paper is that it typically undergoes non-bleached processing, which is one reason for its environmental appeal. Bleached paper often involves chemical bleaching agents, whereas gray kraft paper is produced without bleaching, maintaining its natural look and environmentally friendly characteristics.

4. Ecological and Aesthetic Needs

Gray kraft paper bags are becoming more popular in the eco-friendly packaging market not only for their environmental benefits but also for their modern, minimalist, and premium appearance. The gray color has versatile applications and pairs well with various brand logos and designs, making it suitable for different packaging scenarios.

In conclusion, gray kraft paper bags maintain the natural eco-friendly properties of kraft paper, while the addition of gray dyes or pigments allows them to meet modern consumer demands for both aesthetics and sustainability.
