Flat Bottom Bag Kraft Paper Brown with Pocket Zipper
The flat bottom bag kraft paper brown with pocket zipper is built for semi- and fully automated filling. The pocket zipper keeps the fill opening fully intact, enabling especially efficient filling – a clear advantage over standard zipper versions with a reduced opening.
The aluminium-free multi-layer structure with a high-barrier BOPA layer reliably protects the contents from moisture, oxygen and outside influences – ideal for aroma-sensitive or dense, heavy products. Once filled, the bag remains resealable as often as needed via the pressure closure, for portion-by-portion use without any loss of quality.

Processing & Handling
The pocket zipper is purpose-built for use on filling lines: the opening remains fully usable throughout the process, which reduces cycle times and makes filling easier – both semi- and fully automated.
For the end customer, the built-in tear tab allows an easy first opening with no extra tools. After that, the pressure closure remains reusable as often as needed, and the bag can be additionally heat-sealed with standard sealing equipment if required – for example with a tabletop sealer like the Wusing 405 H.

Frequently Asked Questions
What makes a pocket zipper better suited than a standard zipper?
The pocket zipper keeps the fill opening fully intact, making it especially suitable for semi- and fully automated filling lines with high throughput. For smaller, manually filled volumes, a standard zipper is usually sufficient.
Is the bag aluminium-free?
Yes. The barrier performance comes from a high-barrier BOPA layer instead of aluminium.
Can the bag be resealed after filling?
Yes, after first opening the pocket zipper works like a normal pressure closure and can be resealed as often as needed.
What sizes are available?
Seven sizes from 100 g to 5000 g fill weight, each with matching dimensions – see the size table above.
Is the bag suitable for heavy contents like pet food?
Yes, the exceptional tear resistance makes the bag suitable for heavy, dense contents such as protein powder or pet food.
