Performance Characteristics
- Superior Palletizing: The brick-shape result after filling ensures high stability for sea container loading and warehouse stacking.
- Moisture Protection: Extrusion lamination provides a critical barrier against humidity, preserving the nutritional quality of the feed.
- Sift-Proof Bottom: Block bottom technology eliminates needle holes, making the bag effectively leak-proof for fine particles.
- Auto-Line Compatible: Engineered specifically to work seamlessly with high-speed automatic bag-feeding and filling machinery.
Industry FAQ
Q1: Is this bag compatible with high-speed automatic filling lines? A: Yes. The open mouth design and rigid block bottom ensure the bag remains upright and opens reliably on automatic bag-placers used in industrial feed mills.
Q2: How does the square bottom prevent powder leakage (sifting)? A: The block bottom is formed by high-strength bonding instead of sewing, eliminating the needle holes through which fine particles typically escape.
Q3: How effective is the lamination against humidity? A: The PE lamination layer acts as a physical barrier to water vapor, preventing hygroscopic feed ingredients from clumping during transit.
Q4: What is the drop-test performance for a 25kg load? A: These bags are designed to pass industry-standard drop tests (1.2m to 1.5m) due to the high-tenacity woven fabric and reinforced seal.
Q5: What is the advantage of a square bottom for palletizing? A: It creates a stable, box-like shape when filled, allowing for flat-top stacking which improves pallet stability and safety during storage.
