Excellent Stackability: The square block bottom design ensures the bags stand upright and stack perfectly, saving up to 20% of warehouse and shipping space.

Automatic Self-Closing Valve: Designed for high-speed automatic packing lines; the internal valve sleeve seals automatically by the pressure of the product.
