Can you add a print on the bags ?
Yes, your carrier bag can be custom printed with the design of your choice. But in order to ensure that they can be certified as biodegradable and compostable according to standard EN 13432, the print area should cover max. 30%.
In Switzerland, the Swiss Compost Association recommends in addition the traditional white lattice or honeycomb print so that the bag can be reliably recognized as compostable.
