1 to 4 Layers PE Inner Pasted Multiwall Valve Bags with High Moisture Resistance for Bulk Packaging of Chemicals and Powders

The multi-layer valve bag is crafted using fully wood pulp bleached kraft paper as the core material. It undergoes a sophisticated multi-layer composite process, resulting in a high-quality sealed packaging container equipped with a professional valve structure.

This product combines the load-bearing and protective properties of multiple material layers with the convenient sealing advantages of the valve design. Compared to traditional open-mouth bags, it does not require additional sewing or tying. Once filled, the bag can automatically seal itself.

Such features not only enhance operational efficiency and material protection but also support customized printing. This allows for a triple improvement in practicality, airtightness, and brand presentation, making it a superior packaging solution.

• Efficient and Convenient Valve Seal
• Durable Multi-Layer Composite Construction
• Comprehensive Moisture-Proof Protection

The kraft paper substrate used is made from pure wood pulp stretched kraft paper, ensuring it is free from impurities, damage, and odors. This guarantees the structural stability and durability of the multi-layer composite, meeting the stress requirements for valve sealing.

Environmentally friendly water-based inks are used, free from odors and harmful heavy metals, complying with food-grade packaging standards. Printing accuracy ensures patterns and text are clear and legible without double images, missing prints, or errors.

Our packaging solutions cater to a diverse range of industries including building materials, chemicals, agriculture, food and feed production, industrial raw materials, and export markets.
