Product Introduction

Made using advanced multi-layer kraft paper and high-barrier film lamination, the WM130 paper bag ensures superior moisture resistance and tear strength. It is engineered to maintain product integrity during storage, handling, and transportation, even in humid or demanding environments. With precision bottom-gluing or valve-mouth sealing options, it offers compatibility with automated filling systems widely used in modern industrial packaging lines.

The WM130 waterproofing mortar paper bag reflects Tongying’s commitment to environmental sustainability, quality assurance, and innovative industrial paper packaging for powder-based materials.

Product Features

Multi-Layer Structure for Superior Strength
The bag is constructed with 2 to 4 layers of high-quality kraft paper, optionally laminated with a PE or PP film to provide enhanced tensile strength and durability. This design ensures that the packaging can withstand stacking, transportation, and mechanical filling without tearing.

Excellent Moisture-Proof Performance
The inner waterproof film effectively prevents moisture absorption, keeping the waterproofing mortar or cementitious materials dry and stable during storage. This feature significantly extends the product’s shelf life and maintains consistent quality.

High-Precision Valve or Bottom Gluing Design
The WM130 can be produced as a valve mouth paper bag or bottom-glued bag, supporting both manual and automatic filling lines. The valve design allows efficient filling and automatic sealing, reducing packaging time and labor costs.

Environmentally Friendly and Recyclable
Made from biodegradable kraft paper and non-toxic laminating films, this product aligns with international environmental protection standards. It is an excellent replacement for traditional plastic packaging in construction materials.

Customizable Printing and Branding
Advanced 4–7 color flexographic printing provides sharp, high-resolution brand logos, product information, and safety instructions. Customized printing enhances product recognition and brand image in the marketplace.

High Compatibility with Factory Automation
Fully compatible with modern automatic filling and palletizing systems. The bag’s dimensional stability ensures smooth operation and minimizes downtime.

Optional Anti-Slip and Easy-Open Design
Surface anti-slip coating ensures safe stacking and transport, while the optional easy-tear design allows end users to open the bag conveniently without tools.
