SP GROUP has managed to develop microwavable packaging that is apt for home-toasting several types of seeds and nuts (with and without hulls). The fresh packaged product has a longer shelf life (longer expiry date) than the toasted product, which meant this project had great potential.
The process required materials that were more resistant to high temperatures. The critical points were the fat content and the hulls, which reached temperatures that perforated conventional films. An exhaustive study of new materials was performed and finally a functional, attractive and low-cost packaging was designed that was able to safely withstand the toasting process and could be used with a wide range of our clients’ products.
The company did not need any new machinery to be able to work with this new film, which has been very successful since its launch.
