Features: 1. High-quality material: The bag is made of HDPE material resistant to acid and solvents. Please check compatibility with the filler before use. 2. Usage tips: The inner bag is not designed for standalone use and must be used in conjunction with an IBC barrel. 3. Working temperature: The product operates within a temperature range of -40°C to 80°C. Ensure the filling temperature does not exceed this range. 4. Warm reminder: Before filling, confirm the product fits securely against the inner wall of the IBC barrel. If the seal is loose, remove the air valve cover and release any trapped air. 5. Easy to use: After filling, secure the barrel opening with a lid to prevent contact between the contents and the lid, avoiding contamination. Notice: 1. Actual color may vary slightly due to differences in monitor displays and lighting conditions. 2. Allow for a 1–3 cm measurement deviation due to manual measuring. 3. A valve wrench and blower are required for installation and must be provided separately.
