What is a k-seal stand-up pouch?

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. With us, you can choose between different formats (100 ml, 250 ml, 500 ml, 750 ml, 1000 ml, 1500 ml) or tell us a custom format according to your wishes.

Possible uses of the K-Seal

The possibilities uses of the K-Seal are vast. It can be used to transport solid products, pastes, liquids, or also powders. It is often filled with foodstuffs, hygiene products or cleaning agents for the household.

Which variations of the K-Seal are there?

The K-Seal requires particular designs depending on the area of application. It is important to know exactly what it will be used for later. It is to be used once or more often? What is going to be packed in it?

Labelprint24 offers the K-Seal in different versions. You can choose whether your pouch packaging should have a tear tab, a hanging hole, a Euro hanging hole or no characteristics. Of course, you can also combine the tear tab with a hanging hole. You can see all possible combinations here:

without tear-off hole, with hole suspension

Environmental status of the K-Seal stand-up pouches made of PP and PE

When being disposed of, our composite materials made of the plastics PP (polypropylene) and PE (polyethylene) are first washed, after being sorted, in order to free them from any foreign matter. The material is then processed further. The film can thus be recycled without any further problems. This is not only efficient, but can also save around 60 percent on energy compared to new production.
We have made it our goal to be able to offer you 100% recyclable pouches.
