What type of carton is used in Tetra Pak?
The cardboard used in Tetra Pak packages is made from virgin wood pulp sourced from sustainably managed forests. This is a special type of board known as ‘liquid board’, which is capable of withstanding moisture and liquids for a long period of time without losing its shape or strength.
The liquid carton used in Tetra Pak consists of several layers of intertwined and pressed cellulose fiberswhich give it high mechanical resistance and an excellent capacity to support the weight of the content and mechanical stress during transport and handling.
Tetra Pak uses advanced carton processing and treatment techniques to ensure its quality and food safety. For example, cardboard is subjected to high temperature heat treatment to eliminate any microorganism that may be present in the raw material and to sterilize the cardboard before its use in the manufacture of packaging.

The recycling of Tetra Pak packages is a process that takes into account sustainability and efficiency in the use of resources. The Tetra Pak recycling process is divided into three main stages:
- Separation and collection: Tetra Pak packages are collected at authorized collection points, where they are classified and separated from other types of waste. The packaging is compressed and transported to recycling plants.
- Disintegration: At the recycling plant, Tetra Pak packages are disintegrated into a fiber paste called ‘pulp’. The pulp is subjected to a separation process to eliminate aluminum and plastic from the inner layers of the container. The resulting pulp is then sent to a papermaking plant for reuse in the production of new paper products.
- material recovery: Recovered materials, such as aluminum and plastic, are sent to plants specialized in their recycling and reuse in the production of new products.
