When it comes to packaging and transporting products, safety and reliability are always a
priority. Flexible Intermediate Bulk Containers (FIBCs), often known as bulk bags, already provide
strength and durability for handling a wide range of materials. But in many applications, these
bags perform even better when paired with liners. Adding a liner gives an extra layer of
protection, helping products stay secure and fresh throughout storage and transport.
Why Use FIBC Liners?
FIBC liners are designed to enhance the natural strengths of bulk bags. By creating a cleaner and
more secure inner surface, liners protect sensitive goods from outside contamination. Depending
on the need, liners can be loosely inserted, glued, or stitched into the seams of the bag.
At HPBL, all liners are produced on a five-layer co-extrusion plant and shaped using a fully
automated Gunter machine from Germany. This ensures precision, consistency, and reliable
performance.
Different Types of Liners
Form Fit Liner
Form-fit liners are shaped to match the body of the bulk bag, right down to its filling and
discharge spouts. This close fit improves bag stability, reduces twisting or tearing, and helps
maintain shape. They also enhance compatibility with filling equipment and provide better
protection from contamination during storage and handling.
Baffled Liner
Baffled liners keep a bulk bag in a square shape, preventing bulging that can reduce stability.
With better stack-ability, these liners help save space and improve handling. They can also hold
more product in the same area, while still protecting goods from contamination.
Gusseted Bottom Sealed Liner
Also known as lay-flat liners, these are the most popular and economical type. Simple in design,
they feature an open end and a heat-sealed end. They are available in rolls or pre-installed in
bags, easy to use, strong, and even reusable in some cases.
Suspended Liner
Used mainly in one-loop bags, suspended liners are attached to the outer bag where the lifting
loop is formed. With options like perforation for air release, they make high-speed filling easier
and are compatible with automatic filling systems.
Aluminium Liner
Aluminium or foil liners bring an added level of barrier protection. They guard against moisture,
oxygen, and UV light while also improving filling, discharge, and overall handling. These liners are
suitable for applications where extra protection and durability are required.
Customized Liners for Different Needs
Every product has unique requirements. That’s why HPBL offers liners in various sizes,
thicknesses, and even with customized printing for branding. Food-grade materials are also
used, making them suitable for sensitive products like food and pharmaceuticals.
