Tetra Pak Aptiva sterile paper bottles can be produced on the newly designed Tetra Pak A5 filling machine, which can be manufactured in both personal and family sizes. Both models can be used to package juice drinks, non-carbonated drinks and liquid dairy products. Individual models can produce 12,000 bags per hour, while family models can produce 10,000 bags per hour.

The Tetra Pak A5 uses an innovative filling and forming system that uses familiar rolls of paper-based packaging materials and prefabricated plastic top components. The first step in the bottle forming and filling process is to seal the paper around the axis of the paper-based packaging material so as to form a very precise bottle body and then fuse it with the prefabricated top crown. In this system, the plastic double crowns were placed in two halves and placed on the mandrel wheel respectively, and the paper bottle body was placed on top crown and mandrel wheels. The induction sealing process firmly fuses the two parts together.

The disinfection process is carried out by Tetra Pak's unique hydrogen peroxide-based process. After filling, nitrogen is sprayed inside the package with the goal of minimizing the oxygen content before the final package. Finally, the finalization procedure, which is when the packaging is completed, is to fold out the unique shape and bottom of the Tetra Aptiva sterile paper bottle.

Tetra Aptiva sterile paper bottles have excellent carton barrier properties, ensuring that the oxygen-sensitive products such as fruit juices have a long shelf life (minimum six months). The transparent polypropylene crown allows consumers to see what's inside. It contains a layer of oxygen barrier. The paper bottles used to hold liquid dairy products use translucent polyethylene crowns to block the entrance of light.

Tetra Pak will provide all Tetra Aptiva sterile paper bottle customers with a full range of services as part of their one-stop solution. Tetra Pak also provides a complete packaging line for Aptiva sterile paper bottles, including the previous design, the final installation of the production line, as well as plastic crowns and packaging materials.
