Heat Sealed China Paper IBC Tote Liner Bag Square Form-Fit Design. Food-Grade LDPE Raw Material: This China IBC Liner Bag uses non-toxic virgin PE film, fully compliant with food contact standards for juice, edible oil and beverage concentrate bulk packing. Dual Inlet & Outlet Spout Design: Reinforced sealed spouts simplify filling and draining work, effectively avoiding liquid leakage during bulk liquid sea transport and storage. Perfect Form-Fit Square Shape: Custom sized liner fits standard 1000L metal IBC cage and paper IBC tank tightly, no loose wrinkles to affect liquid delivery efficiency. Disposable One-Time Use Structure: Single-use PE inner liner eliminates tedious IBC tank deep cleaning work, cuts labor cost for food factories and chemical processing plants. Strong Anti-Corrosion Film Performance: Resists mild solvent, acid and fertilizer liquid erosion, suitable for industrial raw liquid, pigment and agricultural liquid packaging. Optional EVOH Barrier Layer: Oxygen-block barrier liner slows oxidation of wine, syrup and edible oil, extending shelf life of bulk food liquids during long-distance shipment. Heat-Sealed Seam Construction: All seams are fully hot sealed without tiny gaps, greatly lowering liquid leak risk in cross-border container logistics. Lightweight Foldable Packaging: Flat folded liners take little warehouse space before use, saving storage expense compared with rigid plastic IBC inner containers. Custom Size & Printing Support: We produce tailor-made IBC liner bags for non-standard IBC tanks, and accept brand logo printing for wholesale bulk buyers. Wide Compatibility For Multi-Scenario Use: Works well with steel IBC frame, cardboard IBC tank and pallet liquid container, covering food, cosmetic, pharmaceutical and chemical industries.
