Lined super sacks also known as jumbo bags with liner have an extra poly liner inside the outer PP bag made from PE plastic (polyethylene) to shield and separate the product from the outside environment. PE liners are tubular bags with open top and their bottom can be sealed or not depending on the bottom of the FIBC bag. For discharge bottom bulk bags, the poly liner will not be welded to facilitate the discharge of goods. You can follow this article to learn more about industrial bulk bags with liners used.
What is the role of lined super sacks?
Jumbo bags are mainly made from woven polypropylene (PP) and have many different sizes and loads to suit different types of goods. The safe working load of a large jumbo bag can be up to 5000kg. They are extremely suitable for storing granular materials such as cement, coal powder, chemicals, rice, flour, coffee, pepper and grains.

However, most of these goods need to have moisture resistance and isolation from the outside environment, therefore, just one layer of PP woven is not enough for good preservation. An extra layer of PE inner liner is required to completely separate the product inside from the outside environment. This PE bag is also necessary when storing ultra-fine grain products, preventing them from being spilled out through small weaving holes on the surface of the big bag.
Features of PE liners
Unlike Lined super sacks, Poly liner is made from LDPE (Low-Density polyethylene), a material with toughness, good strength and resistance to water, moisture and some chemical solvents. They are placed in bulk bags for many types of products, especially foodstuff and pharma. This type of inner liner is used for duffle top FIBC bags and spout top big bags to avoid dropping fine particles out and contaminating the container during transportation.

Lined super sacks both increase bearing capacity, load, and help prevent dropping and dampness of products inside during long-term transportation.
Uses of liner bags
The bags are nested in jumbo bags with thicknesses ranging from 50 -120 microns and manufactured from virgin PE plastic to ensure the best advantages of this material. In addition, when storing products with a risk of explosion, there will be special liner bags that are also resistant to static electricity by adding some additives during the production process.
PE liners will be wide and long depending on the size of the bulk bag. However, with the role of shielding and separating, the liner size must be absolutely larger than the size of the outer FIBCs. Moreover, this liner is also especially effective to store foodstuff such as rice flour, bran, protein or animal feed and avoid bacterial and mold contamination.

For export goods, the use of PE liners is almost mandatory because most foreign markets do not accept drops, dirt and mold during transportation.
