A PE inner liner is used inside a bulk bag when the packed product needs better protection than a standard woven PP FIBC can provide. It creates a clean barrier between the product and the outer bag, helping prevent direct contact with dust, moisture, stains and other outside contaminants.
The form-fit design follows the shape of the parent FIBC bag, including the top spout and bottom discharge outlet. This helps the liner sit neatly inside the bag, reduces trapped material in corners and improves product flow during filling and unloading.
Depending on the product requirement, the liner can be made from LDPE, HDPE, nylon co-extruded film, EVOH barrier film, conductive film or anti-static film. Thickness, size, spout dimensions and material structure can all be customized.

Why Choose a Form-Fit Bulk Bag Liner
Compared with a simple loose liner, a form-fit liner is made to match the shape of the outer FIBC bag. The shaped design helps reduce folds, pockets and dead corners inside the bag. This can improve usable capacity, reduce product residue and make filling or discharge more efficient.
For products that need stronger barrier performance, EVOH, nylon co-extruded or aluminum composite materials can be selected. For electrostatic-sensitive applications, anti-static or conductive liner options are also available.

FAQ
What is a bulk bag PE liner?
A bulk bag PE liner is a plastic inner bag placed inside a FIBC jumbo bag. It helps protect the product from moisture, dust, dirt and contamination.
What is a form-fit liner?
A form-fit liner is shaped to match the inner structure of the FIBC bag. It can include top and bottom spouts, helping the liner fit neatly and improve filling or discharge performance.
Which materials are available for liners?
Common materials include LDPE, HDPE, PE composite film, nylon co-extruded barrier film, EVOH barrier film, anti-static film and conductive film.
Can this liner be used for food packaging?
Yes, food-grade liner materials can be customized according to the packed product and buyer’s requirements.
Can the liner protect against oxygen and water vapor?
Yes. Standard PE liners provide moisture protection. For higher oxygen or vapor barrier requirements, EVOH, nylon or aluminum composite liners can be used.
