WHY Valve Bags Are the Global Trend?
HOW It Works: The “Black Tech” Behind Functional Valve Bags?
01. High Venting & Moisture Resistance – A “Protective Armor” for Powders
Ailu’s valve bags feature a unique venting structure that rapidly releases air during filling while sealing out external moisture post-filling. Ideal for nano-grade carbon black, silica, and other sensitive powders, they ensure long-term physical & chemical stability—like an impenetrable shield for your materials.


02. Auto-Opening Tech – Faster Bag Loading
Traditional paper bags often fail due to poor mouth opening or deformation. Ailu’s self-opening valve design ensures perfect circular form and automatic clamping, eliminating manual adjustments and cutting setup time by 90%.
03. Smart Production – Slashing Labor Costs
Traditional lines require 4–5 workers (3–5 mins/bag). With Ailu’s robotic auto-loading system, filling speeds reach 15 seconds/bag—just 1 operator per line—reducing costs and dominating the competition.
04. Material Versatility – Your “Universal Packaging Vault”
Choose from paper-plastic composite, kraft paper, or PE valve bags, tailored for food, chemicals, construction, or pharmaceuticals. Ailu’s solutions adapt to any industry need.
