Four Common Uses For FIBC Bulk Bag Liners

Updated: 5-18-2022

When it comes to packaging and transporting a variety of goods, FIBC bulk bags are some of the most versatile options on the market. But what many people don't realize is that FIBC bulk bags with liners can also be extremely useful in a variety of situations. 

FIBC bulk bag liners are required for certain products and applications. Plastic liners can 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

In this blog post, we will discuss four common uses for FIBC bulk bag liners that you may not have considered before!

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.

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.

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.

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 over-bag 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 over-bag can serve as an extra barrier when product is shipped.

In summary, FIBC bulk bag liners can be extremely useful in a wide variety of situations. They provide a moisture barrier, keep products safe and fresh, and can serve as an extra barrier when product is shipped. Whether you are packing food, pharmaceuticals, or another type of product, using a liner is often the best way to ensure your goods arrive at their destination in perfect condition.
