PE LINERS & Shrink Films & Pallet Hoods
BIG BAGS & LINERS
Big bags with inliner provide a suitable solution for materials that require a high degree of purity when packed.
The inliner covers the whole inner side of the big bags so the material does not come into contact with the fabric or seams. For very tiny powdery materials dustproof seams are usually not enough. In these cases inliners are used to prevent leakage and provide barrier property to the big bag.
FIBC bulk bag liners are required for certain products and applications. Liners serve multiple purposes including, but not limited to:
LINER TYPES
Standard Liners
Standard liners are like a PE hose covering the interior surfaces of the big bags , but they have some wrinkles to adjust to the big bag shape which may slow down product flow.
Formliner
Formliners are Inliners in the shape of a bottle which adjust to the form of the big bag at the spouts. This allows a smooth material flow within the jumbo bag and also provides easier spout handling during the filling operation.
Q-Liner / Gambo Liner / Baffle liner
Q-liners have baffles from PE inside the liner, which makes the big bag with inliner also a Q-bag at the same time. This is a very cost intensive premium big bag solution.

Liner Materials
The markings must be within a rectangular border with a vertical line separating the IPPC logo (on the left) from the identifying data. The border lines may be solid or broken; and the corners may be rounded.
- PE Blend: The most common and standard liner material. Usually made from LDPE . Available in conductive and antistatic versions. Normally transparent but other colors are also possible such as white , blue and black.
-
Aluminum Foil: High barrier property film available in most shapes. Form shaped aluminum liners, improve filling, discharging, handling and stability of the outside of the bag. Foil liners offer great moisture, oxygen, and UV protection and are compatible with a wide variety of bulk bags.
Very high gas and aroma barrier.

ALU – EVOH – PA
ALU – EVOH – PA liners are known as barrier liners, their main functions are as follows;
- Moisture and oxygen sensitive products storage
- Air, humidity and gas control
- Storage of products with a long shelf life
- Food and pharma products storage
- Storage of materials that need to be protected from external factors
- Storage of products that should not lose their special odor, gas, heat balance and aroma
- Please contact an ATEA expert for more details about liners.
BIG BAG LINER INSERTION OPTIONS
• Loose Inserted inliner : The inliner is simply put inside the big bag without attaching it to the body of the big bag. Preblowing recommended. Loose inserted inliners are mostly used for simple big bags and chosen by customers due to their cost-efficiency.
• Tabbed inliner : The liner is fixed with eight tabbings in the eight corners of the big bag. This prevents efficiently the movement of the liner within the jumbo bag which may otherwise create problems during filling and discharging.
• Sewn-in inliner :Inliner is fixed in the FIBC by sewing along the entire length of the big bag in all four side seams. Inliners that are sewn along the entire length are stronger fixed inside the FIBC than those that are fixed with tabbings. A movement of the liner is efficiently prevented.
• Glued inliner : The inliner is fixed to the walls of the big bag by hotmelt glue. This is an expensive option that provides the firmest attaching. ATEA’s recommendation.

Dimensions of PE inliners are usually determined based on the dimensions of a big bag for which it is used.
Depending on the type and purpose of the material, the thickness of the inliner can vary between 50 -200 microns (my), usually it is 70-80 my for most FIBCs.
For type B and type C big bags, there is a special type of inliner that is electro-conductive.
For big bags with one and two loops almost always a inliner is used. These inliners have a special shape (See suspended inliner).
Inliner can meet the needs for big bags in the food industry. FIBC can be made with special measures for cleanliness.
COMMON USES OF LINERS
#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.
#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.
#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.
#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.
