IBC Paper (or Paper IBC) is an Intermediate Bulk Container—a large industrial container designed to store and transport liquids or bulk materials (granules, powders) in medium volumes. Its main difference from conventional IBCs (made from a steel cage and rigid plastic) is its material, which is mostly made from heavy-duty corrugated cardboard. Paper IBCs are often one-way disposable products (single-use and disposed/recycled), which significantly saves on operational and return costs. The Main Components of a Paper IBC are a system consisting of several important elements:

• Outer Box (Sleeve/Body): This is the main structure made of multi-layer corrugated cardboard (often using Tri-Wall Pak or equivalent material) that provides exceptional compressive strength and stacking power.
• Liner Bag (Inner Bag): This is a crucial component. A large bag made of food-grade plastic (like PE, EVOH, or nylon) that serves to hold the liquid or bulk material. This bag ensures the product is protected from contamination and prevents leaks.
• Lid and Valve: Equipped with a top lid for filling (top-fill) and a flexible discharge valve (bottom-discharge).
• Base Pallet: Usually supported by an integrated wooden or paper pallet at the bottom.
