Featuring an open-mouth design that eliminates complex valve structures, these bags allow for easy and efficient filling, making them perfectly suited for automated filling production lines.
Open bag mouth design eliminates precise alignment requirements, enabling swift material loading and perfect compatibility with high-speed automated packaging lines.
Multi-layer kraft paper lamination provides excellent tensile strength and tear resistance, supporting weights from 20kg to 50kg with options for higher capacities.
Optional PE inner membrane lamination or surface waterproof coating creates dual protective barriers against external moisture, dust, and impurities.
