The shelf life of fresh fruit and vegetables can be extended by several days thanks to the laser micro perforation of packaging film.
Perfon, a company of the Oerlemans Packaging Group - a Dutch manufacturer of flexible packaging films - produces laser micro perforated films. The perforation, which is not visible to the naked eye, creates the right balance between oxygen and carbon dioxide. Thanks to this solution, the product inside the packaging goes into a sort of "sleep". This ensures a longer shelf life which varies depending on the sensitivity of the product to dehydration or condensation. To understand the preservation requirements of a product, it is possible to measure perspiration and monitor fermentation, so as to get an even deeper insight into what is happening inside the package.
Ellen Schreur, product manager at Perfon, stated:
We can use flexographic printing up to 10 colours and the perforation pattern can be changed according to the requirements of the product inside the package. In addition, this technology is suitable for both flowpack packaging and top-seal bags, significantly improving the shelf life of products compared to traditional packaging.
In addition, as part of the search for 100% recyclable plastic solutions, Oerlemans Packaging Group has recently invested in machines incorporating new technologies to produce 100% recyclable barrier films. The added value of this packaging, given by a more efficient preservation of food as well as the prevention of food waste, is meeting with positive feedback from the fruit and vegetable market, which is increasingly oriented towards sustainability.
