Open Top / Flat Bottom FIBC Bags
A straightforward 1-ton bulk bag for dry flowable materials that need efficient filling and stable pallet handling.
FIBC Bulk Bags
Full Open Top / Flat Bottom FIBC Bags with Liner
Full open top flat bottom FIBC bags with liner offer the broadest fill access in the standard FIBC format range, with built-in liner compatibility for materials that need internal barrier protection. The full open top removes all obstructions from the fill area. The liner handles the containment, moisture exclusion, or contamination control requirement that the woven PP body alone does not provide.
Product Overview
About this bag configuration.
The full open top / flat bottom with liner configuration is a woven polypropylene bulk bag with a completely unobstructed top opening and a PE liner supplied for use inside the bag body. The flat sewn bottom provides stable pallet handling. This format is selected when filling systems require maximum top clearance - wide-mouth fill heads, cross-belt loading, or manual loading of materials that benefit from an internal barrier. Common applications include food ingredient handling, fine powders requiring moisture exclusion, and industrial compounds with contamination sensitivity. Liner configurations, closure methods, body fabric options, and print are confirmed at project review.
Typical Applications
Common uses for this bag format.
- Food ingredient operations - dry ingredients, blends, or powders that require an internal barrier between the material and the woven PP bag body
- Fine powders with moisture sensitivity - applications where the liner provides a seal against ambient humidity during storage and transport
- Industrial compounds with contamination requirements - materials that cannot risk contact with particulates from the bag weave
- Clean-fill programs - procurement-specified liner requirements for food, pharmaceutical-adjacent, or regulated material handling
- Wide-mouth filling systems - operations using fill heads or loading equipment that requires maximum top clearance

Why This Format
Why choose this bag style.
The full open top with liner format exists at the intersection of two common requirements: maximum fill access and internal material protection. A standard open top bag handles most dry material applications without a liner. The full open top with liner addresses applications where the liner is non-negotiable - food ingredients that cannot contact the woven PP body directly, fine powders that need moisture exclusion, or compounds that require a clean internal surface. If the liner is the deciding factor in your specification and your fill system needs unrestricted top access, this configuration resolves both requirements without compromise. It is the natural choice when the standard open top gets you to 90% of what you need but the liner pushes the specification over the line.

Product FAQ
Questions that come up during specification review.
What liner options are available for full open top bags?
PE liner options include form-fit liners that conform to the bag body and loose liners that sit inside without being attached. Liner thickness, closure method, and compatibility with your fill system are confirmed at project review. Liners are available with or without a spout at the bottom depending on how the bag will be emptied.
Are the liner options suitable for food ingredient applications?
Food-grade liner suitability is confirmed at project review based on the specific material, regulatory requirements, and handling environment. XTRX does not make blanket food-grade certifications - requirements are reviewed individually as part of the RFQ process.
How is a full open top bag different from a standard open top bag?
The full open top provides a wider, completely unobstructed top opening compared to a standard open top with a sewn top panel. This is useful for filling systems that require maximum clearance - wide-mouth fill heads, cross-belt loading, or manual loading of awkward materials. The liner compatibility built into this configuration addresses the barrier protection requirement that often comes with wider fill access.
What materials are typically handled in full open top bags with liner?
Common applications include dry food ingredients that cannot contact the woven PP body, fine powders requiring moisture exclusion, industrial compounds with contamination sensitivity, and clean-fill programs where an internal barrier is specified. The liner requirement is usually the deciding factor in selecting this format over a standard open top.
Can XTRX support custom bag sizing and specifications?
