Description
High Moisture Resistance Paper Valve Bags
Using natural brown or white kraft paper with valve closure designed for automatic filling
Product Overview
The kraft paper valve bag is a specialized packaging solution designed specifically for ultra-fine powders, chemical powders, and building material granules. This fully automatic filling packaging system ensures efficient and precise packaging, catering to the demanding needs of these industries.
Manufactured using a multilayer high-strength virgin kraft paper composite inner film process, the bag provides excellent durability and protection. The valve bag features a square bottom valve structure, which effectively replaces traditional open-mouth bags, offering enhanced convenience and improved sealing performance.
Currently, this type of packaging has become the mainstream standardized choice across several industries, including carbon black, white carbon black, titanium dioxide, pigments, additives, and building material powders.

Key Features
  • Valve Mouth Self-Sealing and Zero Dust Leakage: Inner and outer valves are precisely compatible with fully automatic filling equipment. After filling, air pressure automatically seals the valve, eliminating manual sealing and preventing powder dust, leakage, and contamination.
  • Stable Stackable Three-Dimensional Square Bottom: Integrally formed square bottom maintains firm, upright shape. Even load distribution prevents tilting or collapsing, ideal for high-level warehouse storage and container sea transportation.
  • Multi-layer Thickened Material with Strong Impact Resistance: Made from 2 to 4 layers of full wood pulp stretch kraft paper with high tensile strength and toughness. Resists tearing and punctures during long-distance transport and handling.
  • Moisture-Proof Lining to Prevent Caking and Deterioration: Food-grade PE moisture-proof inner membrane isolates air, water vapor, and humidity. Prevents ultrafine powders from absorbing moisture, caking, discoloring, or losing performance.
  • Compatible with High-Speed Automated Production: Uniform shape and hardness with precisely fitting valve mouth compatible with various domestic and international powder automatic filling machines.
  • Clear Printing and High Brand Recognition: Supports high-definition flexographic and full-page printing for company logos, product models, net weight, standards, and export labels.
