This packaging takes its name from the triangular sealed shape of the base where, with a bit of imagination, you can see a letter ‘K’. This base construction enables the packaged product to help support the stand-up pouch. This makes the K-seal stand-up pouch a stable, upright packaging with good presentation properties. That’s why the K-seal is often used to pack bulk material and for larger volumes of liquid products, such as screenwash.


The K-seal stand-up pouch is characterised by the special shape of its weld seams at the bottom. These form the shape of the letter "K", which is why it is also called a K-seal or K-bottom. Thanks to this base, it is very stable and can stand upright. It is manufactured either as a plastic pouch, which is usually made of polypropylene, polyethylene, or a combination of PET-PE (polyethylene terephthalate-polyethylene) and PET-PP (polyethylene terephthalate-polypropylene), or as a paper pouch. The weld seams only take up little space, which results in a large filling volume.

It is available in various designs, formats and materials. Different versions must be selected depending on the area of application. The K-Seal can be used for food products or non-food products.

Thanks to its material, the K-Seal stand-up pouch has high barrier properties against oxygen, carbon dioxide, aromas, flavours and water vapour.

All about packaging

K-seal stand-up pouch is also called corner and bottom stand-up pouch and used when the ingredient of the stand-up pouch is between 0,55 kg and 2,0 kg.

K-seal stand-up pouch has seals at the bottom corners as corner seal stand-up pouch plus seals at the bottom folds that resemble the letter “K”.

The bottom of K-seal pouches can be produced with smaller gussets so the same volume of the product seems to require a slightly taller or wider bag than the doyen style stand-up pouches.
