FIBC liners is a core topic on the National Bulk Bag blog. In fact, if you click here you can check out all of the great content we’ve written on liners. However, because we’ve covered the various types, uses, constructions and material types over a long period, a lot of our content is scattered through many blogs.
For an industrial product that seems so simple at first glance, it’s truly amazing how many combinations and variations of bulk bags there are. After all, how much different can one bag be from another? The answer: quite a bit, and it’s no different for bulk bag liners. Sure, a bag liner is simply a polyethylene plastic bag* that is placed into an existing bag – but they aren’t all the same. That brings us to today’s discussion regarding tubular liners. What is a tubular liner? How does it differ from a standard FIBC liner? Let’s explore.
The use of FIBC liners has significantly increased as bulk bags are used with increasing frequency in the food, pharmaceutical, and chemical industries. This has created the need for better information on what liner to use with what products and applications.
For many different products and applications specialty bags like coated FIBCs and FIBCs with pre-installed liners are required for safe bulk bag use. However, how do you know when to use a lined bag? Or when to use a coated bag? We get asked this question a lot at National Bulk Bag so we attempt to answer that question in this blog post.
Polyethylene liners, commonly referred to as poly liners, are flexible plastic liners specifically designed to line the inside of a flexible intermediate bulk container (FIBC or bulk bag).
FIBC bulk bag liners are required for certain products and applications. Liners serve multiple purposes including, but not limited to:
FIBCs (flexible intermediate bulk containers) are fantastic for transporting and storing large quantities of product safely and efficiently. They are commonly used in numerous industries including but not limited to agriculture, chemical, pharmaceutical, pet food, and metals & mining. In many of these industries, a bag is not enough and needs to be paired with a bag poly liner.
