At our farm located near Brussels we grow asparagus, endives and Brussels Sprouts. The Brussels sprouts are grown for the Belgium market but also for export to other European countries, USA, Canada and Asia. We use a PerfoTec laser system on our packaging machines to adjust the amount of perforations in the packaging films. By measuring the respiration rate of the Brussels Sprouts daily and based on the specifications of the transport to the shop we can choose the correct transpiration rate of the bags to extend the shelf life of the product. Since we started using this technology we saw a significant increase in shelf life for the Brussels sprouts, we can now store or transport in bags for more than 2 weeks without any weight or quality loss.
