Product Introduction

The Carbon Black Paper Bag is a high-performance, multi-layer industrial paper packaging solution specifically designed for storing and transporting carbon black powder and other fine chemical materials. Produced by Shenzhen Tongying Environmental Protection Packaging Technology Co., Ltd, a leading manufacturer of environmentally friendly industrial paper packaging, this product combines excellent strength, moisture resistance, and sealing performance with sustainable and eco-friendly materials.

Carbon black is a fine, lightweight, and highly dispersive powder used extensively in the rubber, plastic, ink, and coatings industries. Due to its powdery and easily airborne nature, packaging materials for carbon black require superior barrier properties, anti-leakage performance, and mechanical durability. Our Carbon Black Paper Bags are designed to meet these demanding requirements, ensuring that the material remains protected during filling, handling, transport, and storage.

Made from high-quality multi-layer kraft paper combined with optional PE or PP film liners, the bags provide both mechanical strength and moisture protection. They are compatible with various automated filling and sealing equipment, ensuring efficient and contamination-free packaging in industrial production environments.

Product Features

High-Strength Multi-Layer Structure
Each Carbon Black Paper Bag is constructed using 3–4 layers of high-strength kraft paper with optional inner PE coating. This structure provides superior tensile and burst strength, effectively preventing breakage or leakage during transportation and stacking.

Excellent Moisture and Dust Resistance
The inner layer of PE or PP film provides a strong moisture barrier that protects the carbon black powder from humidity. The tightly sealed structure minimizes dust generation and prevents product loss during handling.

Eco-Friendly and Recyclable Materials
All materials used in the paper bag are environmentally friendly and recyclable. The product meets international environmental standards and supports corporate sustainability goals for green packaging.

Precision Valve Mouth Design
The valve-type mouth allows for easy, fast, and clean filling of carbon black powder. It is compatible with various automatic filling machines, ensuring stable sealing and efficient packaging processes.

Customizable Printing and Specifications
The bag can be printed with up to 7 colors using flexographic printing for brand logos, handling instructions, or hazard warnings. Sizes, structures, and specifications can be customized based on the customer’s filling system, product density, and handling requirements.

High Compatibility with Automated Equipment
The Carbon Black Paper Bag is fully compatible with automatic filling and palletizing systems used in modern industrial plants, improving packaging efficiency and reducing labor costs.

Product Advantages

Safe and Clean Packaging for Fine Powders
Designed to handle lightweight, fine, and easily dispersed powders, the Carbon Black Paper Bag prevents powder leakage and environmental contamination. Its tight sealing system ensures safe transportation and storage.

Excellent Stacking and Transport Stability
Thanks to its durable multi-layer paper and precise folding design, the bag maintains a stable shape even under heavy loads, reducing the risk of deformation or bursting during long-distance shipment.

Cost-Effective and Sustainable
Compared to plastic or woven polypropylene bags, paper bags are more eco-friendly and cost-effective. They reduce carbon footprint while maintaining excellent performance in industrial packaging.

Supports Brand Visibility
High-quality flexographic printing allows customers to showcase their brand, product name, and safety warnings clearly, helping improve product recognition and marketing effectiveness.

Adaptable to Multiple Filling Systems
The product can be used with manual or fully automatic valve bag filling systems, suitable for high-speed industrial packaging operations.

Applications

The Carbon Black Paper Bag is specifically engineered for packaging carbon black powder, but it is also suitable for other fine powders and granular materials in various industries:

Chemical Industry: Carbon black, titanium dioxide, calcium carbonate, zinc oxide, pigments, dyes, and catalysts.

Rubber and Plastics Industry: Raw materials such as carbon black, silica, and masterbatches.

Construction Materials: Cement additives, waterproofing powders, dry mortars, and fillers.

Mineral Products: Limestone powder, quartz powder, bentonite, and talc.

Food and Feed Industry: Powdered additives, animal feed ingredients, and starch-based products (when using food-grade paper).

Each bag can be designed according to the specific density and flow characteristics of the material being packaged to ensure optimal filling efficiency and sealing integrity.
