Tetra Pak: Hygienic efficiency under demanding conditions
Freudenberg ensures clean processes and safe products
Safe food processing starts with the right seal. For Tetra Pak’s newly developed tubular heat exchanger, Freudenberg Sealing Technologies has developed a customized sealing solution that meets the highest hygienic standards of the food industry.
Tailor-made solutions for the highest standards
As one of the three companies in the Tetra Laval Group, Tetra Pak develops and produces innovative processing and packaging equipment for foods and beverages – from liquid food products to ice cream, vegetables or even pet food. In doing so, they focus on the development of safe and hygienic processing and packaging for foods and beverages. The supply of complete systems for processing, packaging and distribution not only protects foods and beverages and their taste, but also prevents them from being wasted and minimizes the use of resources.
The requirements
- Hygienic Design
- Compliance with international legal regulations
- Resistance to varying temperatures and cleaning processes
- Long operating lifetime

Efficient development through digitalization and service
Thanks to Freudenberg’s digital modelling possibilities, the lifetime behaviour of the seal could be predicted early in the development process. With the help of Freudenberg Xpress® suitable prototypes could quickly, precisely, and resource-efficiently be produced to thoroughly test the products.
Durable under many conditions
The new seal combines advanced materials that effortlessly withstand both extreme temperatures and frequent cleaning processes. As a result, the system remains consistently safe and hygienic – an essential advantage in food processing.
