FIBC bulk bag liners are required for certain products and applications. Liners serve multiple purposes including, but not limited to:
- Acting as an oxygen barrier
- Acting as a moisture barrier
- Acting as a chemical barrier
- Reducing static electricity
Let’s examine four common uses for this packaging option.

Common Use #1: Fine Powders
Flexible Intermediate Bulk Containers with coating or sift proof seams work well for a variety of powdered products. But when sift proofing is not enough to keep a fine powder from leaking through the sew lines, a polyethylene liner can be a great solution. Liners can be purchased separately and manually inserted into the bag, or manufactured with the liner already inserted to make the packing process more efficient. Liners also provide a moisture barrier keeping moisture in as well as keeping moisture out – which can be extremely important when working with fine powders.
Common Use #2: Food Grade Products
FIBCs are becoming increasingly popular for packing food or food related products. If the product being packed is an powdered, granular, or dry flow-able form, food grade liners can help keep product fresh and free from contamination. If the food product is in powdered form, liners can help with discharge of product so the end user gets all contents out of the bag.
Common use #3: Pharmaceutical Products
Pharmaceutical products are often held to the same, if not more, stringent standards as food grade products and often require liners. Additionally, many pharmaceutical products are sensitive to elements such as moisture and UV rays making liners essential when transporting these materials.

Common use #4: Over the Bag
Liners are commonly used inside bulk bags, but there are many applications where it makes sense to use polyethylene liners over the bag. An overbag liner is put under the bag before it is filled. After the bag has been filled, the poly liner is pulled over the bag and tied. When used properly, the overbag can serve as an extra barrier when product is shipped.
