4-Side Seal Bags
A four-side seal pouch has four seals on its four edges, a rectangular or square shape and a flat base, so it stands firmly on display. The KOVAA catalogue positions this pouch for products that need an attractive shelf presence, organic food and pharmaceuticals; the models on the website focus on coffee and tea.
The pouch is usually made from PET/PE, BOPP/CPP, PET/AL/PE, BOPP/PE or Nylon/PE laminates, or kraft paper with a silver barrier layer inside. For roasted coffee, a one-way valve can be fitted to release CO2; a zip and tear notch are optional. The four flat faces give a large print area for the logo and product information.

Frequently Asked Questions
- Can a four-side seal coffee pouch have a one-way valve?
- Yes. Many four-side seal coffee pouches have a one-way valve that lets CO2 from roasted coffee escape without letting outside air in. Four-side seal coffee pouches are usually made from PA/PE, PET/PE, PET/MPET/PE, PET/AL/PE or kraft paper with a silver inner layer.
- How does a four-side seal pouch differ from an eight-side seal pouch?
- A four-side seal pouch has four seals on its four edges and a flat base. An eight-side seal pouch has eight seals, four on the base and four on the sides, forming a wide square box-like base, and usually has a zip. The four flat faces of a four-side seal pouch are convenient for brand printing.
- What materials are used for four-side seal tea pouches?
- Four-side seal tea pouches use laminated film, kraft paper or silver foil film to keep the tea aroma and resist moisture. Tea that must keep for a long time should use a structure with an aluminium or MPET layer.
