What is Valvo Pack ?

A simple and easy way to cook and pasteurise food in a flexible packaging  (bag) or rigid (PP, CPET, metal,…) thanks to a steam treament (without opposite pressure) or micro-wave (industrial or at home).

How it works: The sticker valve is placed on the lid film after making a punching hole on the film thanks to automatic or selmi-automatic equipment.

Working principle: the valve opens at 70°C to allow gases to escape out of the pack during cooking and it close at the same temperature to allow closing the pack under positive. Nutripack is helping you in your process and can assist you on site.
