Product Introduction

Made with high-strength kraft paper, reinforced adhesive lamination, and optional PE or PP film liners, this paper bag ensures exceptional protection against moisture, leakage, and contamination during storage, handling, and transportation. The bag is compatible with automatic filling machines and high-speed sealing lines, helping manufacturers in the construction and chemical industries achieve efficient, dust-free, and environmentally sustainable packaging operations.

Our paper bags are widely used for cementitious waterproofing powders, crystalline waterproofing materials, dry mortars, tile adhesives, and building chemicals. Designed to meet the requirements of modern construction packaging standards, this product guarantees strength, reliability, and compliance with green packaging trends.

Product Features

Multi-layer Kraft Paper Construction
The bag is composed of 2–4 layers of high-quality kraft paper, optionally combined with PE or PP liners. This layered structure provides outstanding tensile strength and puncture resistance, ideal for heavy-duty cement-based products.

Excellent Moisture and Water Resistance
The paper bag features an internal barrier coating or laminated plastic film to prevent moisture absorption, keeping the cementitious materials dry and maintaining their chemical activity.

High Sealing Performance
Available in valve-type or bottom-gluing bag structures, our waterproofing material bags ensure secure sealing, preventing powder leakage during transport or stacking.

Eco-Friendly and Recyclable Materials
Manufactured using environmentally friendly raw materials, this paper bag meets sustainable development standards. It is 100% recyclable and biodegradable, contributing to eco-conscious industrial packaging.

Customizable Design Options

Printing: 4–7 color flexographic printing available for branding and product information.

Size and structure: customizable according to product weight (10kg–50kg).

Options: PE lining, anti-slip surface, M-shaped folded sides for improved stability.

Compatibility with Automatic Equipment
The bags are suitable for automatic filling and sealing machines, ensuring consistent efficiency and reduced labor costs in industrial packaging lines.

Strong Load-Bearing Capacity
High bursting strength and tear resistance make the bag suitable for heavy materials, including crystalline waterproofing compounds, cement additives, and mineral-based products.

Key Advantages

Superior Protection for Sensitive Materials
Cementitious waterproofing materials are prone to moisture damage. Our paper bag provides a stable micro-environment that preserves powder quality, enhances shelf life, and reduces wastage.

Reduced Powder Leakage and Dust Emission
The sealed construction and optional valve mouth design effectively minimize dust escape, improving workplace cleanliness and operator safety.

Sustainable Packaging Solution
Unlike traditional plastic bags, Tongying’s paper bags reduce environmental impact by replacing non-degradable packaging materials with green, recyclable paper solutions.

Enhanced Brand Presentation
With high-definition flexographic printing, your logo, product details, and safety information can be clearly displayed, improving brand visibility and market recognition.

Global Export Quality
The bag meets international packaging standards, making it suitable for global export markets including Europe, Southeast Asia, the Middle East, and South America.

Custom Engineering for Product Compatibility
Tongying engineers analyze each customer’s material characteristics, filling methods, and transport conditions to recommend optimal paper bag types—whether bottom-glued, seam-sealed, or valve-mouth packaging.
