There are more and more fresh foods that are packaged to preserve their shelf life, among which we find products such as meat, fish, fruit and vegetables. They are products that produce water vapour due to their own natural perspiration and high water content. That is why fresh food packaging is complex since it needs specific qualities to guarantee that the product will be preserved without losing any quality, but also that the water vapour it can generate does not hinder the product visibility.
That is why it is very important to take into account the characteristics of the product and to provide the final material with the necessary qualities. In the case of fresh foods, an essential feature in addition to water vapour and oxygen barriers is the anti-fog quality.
In packaging for fresh meat and fish, priority must be given to safety, closely linked to good conservation. It is very important that the packaging should have the necessary characteristics to preserve the product and allow its visibility on the shelf.
The packaging of fruit and vegetables is becoming more common on supermarket shelves and is exemplified by the prepared salads or pre-cut fruit. Both products have a high water content, which means avoiding the concentration of mist inside the packaging with the application of anti-mist qualities.
Due to the wide variety of fresh foods, there are a large number of packaging options. Each type of product has specific packaging. With regard to meat and fish, the use of trays is common, so at Rotor Print we ensure the strong-barrier multilayer complexes for the film coating. The other formats used for fresh food packaging are the Flowpack or the Pillow bag.
