Fresh birch sap can be kept for 90 days but to extend the shelf life, the sap is lightly pasteurized for a few minutes at 60°c while still maintaining the quality of the product. Smurfit Kappa Bag-in-Box® was therefore able to create a perfect packaging solution for the drink that keeps it fresh for up to 24 months before opening and 8 weeks after opening. What's more, the pack is environmentally friendly and easy to use. To increase its production capacity, Fée Nature invested in a brand new BIB 700 automatic machine that was installed in February, just in time for this season's harvest.
